82-642: The National Vital Statistics System includes the following data sets and publications: All data is accessible online on the NVSS website. The following programs are related to the National Vital Statistics System: Data from the National Vital Statistics System has been cited in academic research on many topics, including births and homicides. A 1995 paper by Weed for Population Index described

164-428: A sample survey is an investigation about the characteristics of a phenomenon by means of collecting data from a sample of the population and estimating their characteristics through the systematic use of statistical methodology. The main advantages are the direct control over data collection and the possibility to ask for data according to statistical definitions. Disadvantages include the high cost of data collection and

246-468: A significant comparison, numbers must be altered for the size of the population that is under study. For example, the fertility rate is calculated as the ratio of the number of births to women of childbearing age to the total number of women in this age range. If these adjustments were not made, we would not know if a nation with a higher rate of births or deaths has a population with more women of childbearing age or more births per eligible woman. Within

328-727: A common basis like the two standards of the International Monetary Fund , SDDS for Special Data Dissemination Standard (SDDS) and General Data Dissemination System (GDDS). Their aim is to guide countries in the dissemination of their economic and financial data to the public. Once approved, these standards have to be observed by all producers of official statistics and not only by the NSO. Demography Demography (from Ancient Greek δῆμος ( dêmos )  'people, society' and -γραφία ( -graphía )  'writing, drawing, description')

410-401: A country (or other entity) contains Population t persons at time t . What is the size of the population at time t + 1 ? Natural increase from time t to t + 1: Net migration from time t to t + 1: These basic equations can also be applied to subpopulations. For example, the population size of ethnic groups or nationalities within a given society or country is subject to

492-484: A field of sociology , though there are a number of independent demography departments. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration . In the context of human biological populations, demographic analysis uses administrative records to develop an independent estimate of

574-453: A general interest include the media, schools and the general public. They use official statistics in order to be informed on a particular topic, to observe trends within the society of a local area, country, region of the world. Users with a business interest include decision makers and users with a particular interest for which they want more detailed information. For them, official statistics are an important reference, providing information on

656-460: A new product, and to analyze certain dynamics of a company's workforce. Choosing a new location for a branch of a bank, choosing the area in which to start a new supermarket, consulting a bank loan officer that a particular location would be a beneficial site to start a car wash, and determining what shopping area would be best to buy and be redeveloped in metropolis area are types of problems in which demographers can be called upon. Standardization

738-666: A particular topic or geographical area, make comparisons between countries or understand changes over time. Official statistics make information on economic and social development accessible to the public, allowing the impact of government policies to be assessed, thus improving accountability. Official statistics provide a picture of a country or different phenomena through data, and images such as graph and maps . Statistical information covers different subject areas ( economic , demographic , social etc.). It provides basic information for decision making , evaluations and assessments at different levels. The goal of statistical organizations

820-498: A period of transition where in demography emerged from statistics as a separate field of interest. This period included a panoply of international 'great demographers' like Adolphe Quetelet (1796–1874), William Farr (1807–1883), Louis-Adolphe Bertillon (1821–1883) and his son Jacques (1851–1922), Joseph Körösi (1844–1906), Anders Nicolas Kaier (1838–1919), Richard Böckh (1824–1907), Émile Durkheim (1858–1917), Wilhelm Lexis (1837–1914), and Luigi Bodio (1840–1920) contributed to

902-470: A presentation. Sometimes a picture is worth a thousand words. Graphs and charts usually have a heading describing the topic. There are different types of graphic but usually the data determine the type that is going to be used. Official statistics are part of our everyday life. They are everywhere: in newspapers, on television and radio, in presentations and discussions. For most citizens, the media provide their only exposure to official statistics. Television

984-457: A research interest are universities, consultants and government agencies . They generally understand something about statistical methodology and want to dig deeper into the facts and the statistical observations; they have an analytical purpose in inventing or explaining interrelations of causes and effects of different phenomena. In this field, official statistics are also used to assess a government's policies. One common point for all these users

1066-426: A standardized mortality rate (SMR) or standardized incidence rate (SIR). Population change is analyzed by measuring the change between one population size to another. Global population continues to rise, which makes population change an essential component to demographics. This is calculated by taking one population size minus the population size in an earlier census . The best way of measuring population change

1148-499: A variety of demographic methods for modelling population processes. They include models of mortality (including the life table , Gompertz models , hazards models , Cox proportional hazards models , multiple decrement life tables , Brass relational logits), fertility (Hermes model, Coale -Trussell models, parity progression ratios ), marriage (Singulate Mean at Marriage, Page model), disability ( Sullivan's method , multistate life tables), population projections ( Lee-Carter model ,

1230-542: A way that facilitates proper interpretation and meaningful comparisons. To reach the general public and non-expert users when disseminating, NSOs have to add explanatory comments to explain the significance of the results released and make analytical comments when necessary. There is a need to identify clearly what the preliminary, final and revised results are, in order to avoid confusion for users. All results of official statistics have to be publicly accessible. There are no results that should be characterized as official and for

1312-611: Is a database that is updated continuously for a specific purpose and from which statistics can be collected and produced. It contains information on a complete group of units. An advantage is the total coverage even if collecting and processing represent low cost . It allows producing more detailed statistics than using surveys. Different registers can be combined and linked together on the basis of defined keys (personal identification codes, business identification codes, address codes etc.). Moreover, individual administrative registers are usually of high quality and very detailed. A disadvantage

1394-417: Is because developed countries have proportionally more older people, who are more likely to die in a given year, so that the overall mortality rate can be higher even if the mortality rate at any given age is lower. A more complete picture of mortality is given by a life table , which summarizes mortality separately at each age. A life table is necessary to give a good estimate of life expectancy. Suppose that

1476-431: Is likely to continue to rise. Populations can change through three processes: fertility, mortality, and migration. Fertility involves the number of children that women have and is to be contrasted with fecundity (a woman's childbearing potential). Mortality is the study of the causes, consequences, and measurement of processes affecting death to members of the population. Demographers most commonly study mortality using

1558-550: Is seen as the intellectual father of ideas of overpopulation and the limits to growth. Later, more sophisticated and realistic models were presented by Benjamin Gompertz and Verhulst . In 1855, a Belgian scholar Achille Guillard defined demography as the natural and social history of human species or the mathematical knowledge of populations, of their general changes, and of their physical, civil, intellectual, and moral condition. The period 1860–1910 can be characterized as

1640-419: Is the possible under-coverage that can be the case if the incentive or the cultural tradition of registering events and changes are weak, if the classification principles of the register are not clearly defined or if the classifications do not correspond to the needs of statistical production to be derived from them. There are different types of registers: Even though different types of data collection exist,

1722-473: Is the statistical study of human populations : their size, composition (e.g., ethnic group, age), and how they change through the interplay of fertility (births), mortality (deaths), and migration. Demographic analysis examines and measures the dimensions and dynamics of populations; it can cover whole societies or groups defined by criteria such as education , nationality , religion , and ethnicity . Educational institutions usually treat demography as

1804-554: Is the case in much of the developing world, and most of historical demography . One of these techniques in contemporary demography is the sister method, where survey researchers ask women how many of their sisters have died or had children and at what age. With these surveys, researchers can then indirectly estimate birth or death rates for the entire population. Other indirect methods in contemporary demography include asking people about siblings, parents, and children. Other indirect methods are necessary in historical demography. There are

1886-602: Is the first and most important principles to be respected for national statistical offices. When releasing information, data and official statistics should be relevant in order to fulfil the needs of users as well as both public and private sector decision makers. Production of official statistics is relevant if it corresponds to different user needs like public, governments, businesses, research community, educational institutions, non-governmental organizations (NGOs) and international organizations or if it satisfies basic information in each area and citizen's right to information. Once

1968-435: Is the primary news source for citizens in industrialized countries, even if radio and newspapers still play an important role in the dissemination of statistical information. On the other hand, newspapers and specialized economic and social magazines can provide more detailed coverage of statistical releases as the information on a specific theme can be quite extensive. Official statistics provides us with important information on

2050-447: Is their need to be able to trust the official information. They need to be confident that the results published are authoritative and unbiased. Producers of official statistics must maintain a reputation of professionalism and independence. The statistical system must be free from interference that could influence decisions on the choice of sources, methods used for data collection, the selection of results to be released as official, and

2132-630: Is to produce relevant, objective and accurate statistics to keep users well informed and assist good policy and decision-making. The Fundamental Principles of Official Statistics were adopted in 1992 by the United Nations Economic Commission for Europe , and subsequently endorsed as a global standard by the United Nations Statistical Commission. According to the first Principle "Official statistics provide an indispensable element in

2214-432: Is today widely taught in many universities across the world, attracting students with initial training in social sciences, statistics or health studies. Being at the crossroads of several disciplines such as sociology , economics , epidemiology , geography , anthropology and history , demography offers tools to approach a large range of population issues by combining a more technical quantitative approach that represents

2296-510: Is used in a wide variety of contexts. For example, it is often used in business plans, to describe the population connected to the geographic location of the business. Demographic analysis is usually abbreviated as DA. For the 2010 U.S. Census, The U.S. Census Bureau has expanded its DA categories. Also as part of the 2010 U.S. Census, DA now also includes comparative analysis between independent housing estimates, and census address lists at different key time points. Patient demographics form

2378-421: Is using the intercensal percentage change. The intercensal percentage change is the absolute change in population between the censuses divided by the population size in the earlier census. Next, multiply this a hundredfold to receive a percentage . When this statistic is achieved, the population growth between two or more nations that differ in size, can be accurately measured and examined. For there to be

Population composition is the description of population defined by characteristics such as age, race , sex or marital status . These descriptions can be necessary for understanding

2542-666: The Leslie Matrix ), and population momentum ( Keyfitz ). The United Kingdom has a series of four national birth cohort studies, the first three spaced apart by 12 years: the 1946 National Survey of Health and Development , the 1958 National Child Development Study , the 1970 British Cohort Study , and the Millennium Cohort Study , begun much more recently in 2000. These have followed the lives of samples of people (typically beginning with around 17,000 in each study) for many years, and are still continuing. As

2624-516: The Middle Ages , Christian thinkers devoted much time in refuting the Classical ideas on demography. Important contributors to the field were William of Conches , Bartholomew of Lucca , William of Auvergne , William of Pagula , and Muslim sociologists like Ibn Khaldun . One of the earliest demographic studies in the modern period was Natural and Political Observations Made upon

2706-572: The United States and much of Europe ), registry statistics are the best method for estimating the number of births and deaths. A census is the other common direct method of collecting demographic data. A census is usually conducted by a national government and attempts to enumerate every person in a country. In contrast to vital statistics data, which are typically collected continuously and summarized on an annual basis, censuses typically occur only every 10 years or so, and thus are not usually

2788-453: The energy field: Official statistics are intended for a wide range of users including governments (central and local), research institutions, professional statisticians, journalists and the media, businesses, educational institutions and the general public. There are three types of users: those with a general interest, business interest or research interest. Each of these user groups has different needs for statistical information. Users with

2870-666: The life table , a statistical device that provides information about the mortality conditions (most notably the life expectancy) in the population. Migration refers to the movement of persons from a locality of origin to a destination place across some predefined, political boundary. Migration researchers do not designate movements 'migrations' unless they are somewhat permanent. Thus, demographers do not consider tourists and travellers to be migrating. While demographers who study migration typically do so through census data on place of residence, indirect sources of data including tax forms and labour force surveys are also important. Demography

2952-433: The social dynamics from historical and comparative research. This data is often compared using a population pyramid . Population composition is also a very important part of historical research. Information ranging back hundreds of years is not always worthwhile, because the numbers of people for which data are available may not provide the information that is important (such as population size ). Lack of information on

3034-751: The Application of Probabilities to Life Contingencies (1838). In 1755, Benjamin Franklin published his essay Observations Concerning the Increase of Mankind, Peopling of Countries, etc. , projecting exponential growth in British colonies . His work influenced Thomas Robert Malthus , who, writing at the end of the 18th century, feared that, if unchecked, population growth would tend to outstrip growth in food production, leading to ever-increasing famine and poverty (see Malthusian catastrophe ). Malthus

3116-564: The Bills of Mortality (1662) by John Graunt , which contains a primitive form of life table . Among the study's findings were that one-third of the children in London died before their sixteenth birthday. Mathematicians, such as Edmond Halley , developed the life table as the basis for life insurance mathematics. Richard Price was credited with the first textbook on life contingencies published in 1771, followed later by Augustus De Morgan , On

3198-485: The Internet, or completed by an enumerator visiting respondents, or contacting them by telephone. An advantage is that censuses provide better data than surveys for small geographic areas or sub-groups of the population. Census data can also provide a basis for sampling frames used in subsequent surveys. The major disadvantage of censuses is usually the high cost associated with planning and conducting them, and processing

3280-431: The NSO but to all producers of official statistics. Therefore, not every figure reported by a public body should be considered as official statistics, but those produced and disseminated according to the principles. Adherence to these principles will enhance the credibility of the NSO and other official statistical producers and build public trust in the reliability of the information and results that are produced. Relevance

A similar dataset for Europe has been developed by the Euro-Area Business Cycle Network. There are two sources of data for statistics. Primary, or "statistical" sources are data that are collected primarily for creating official statistics, and include statistical surveys and censuses. Secondary, or "non-statistical" sources, are data that have been primarily collected for some other purpose (administrative data, private sector data etc.). A statistical survey or

3444-555: The advanced agencies provide the information on their websites in an understandable way, often categorized for different groups of users. Several glossaries have been set up by different organizations or statistical offices to provide more information and definitions in the field of statistics and consequently official statistics. The quality criteria of a national statistical office are the following: relevance, impartiality, dissemination, independence, transparency, confidentiality, international standards . There principles apply not only to

3526-467: The basic demographic equation holds true by definition, in practice the recording and counting of events (births, deaths, immigration, emigration) and the enumeration of the total population size are subject to error. So allowance needs to be made for error in the underlying statistics when any accounting of population size or change is made. The figure in this section shows the latest (2004) UN ( United Nations ) WHO projections of world population out to

3608-413: The best estimates are based on a combination of different sources providing the strengths and reducing the weakness of each individual source. Official statistics can be presented in different ways. Analytical texts and tables are the most traditional ways. Graphs and charts summarize data highlighting information content visually. They can be extremely effective in expressing key results, or illustrating

3690-696: The best source of data on births and deaths. Analyses are conducted after a census to estimate how much over or undercounting took place. These compare the sex ratios from the census data to those estimated from natural values and mortality data. Censuses do more than just count people. They typically collect information about families or households in addition to individual characteristics such as age, sex, marital status, literacy/education, employment status, and occupation, and geographical location. They may also collect data on migration (or place of birth or of previous residence), language, religion, nationality (or ethnicity or race), and citizenship. In countries in which

3772-518: The category of standardization , there are two major approaches: direct standardization and indirect standardization. A stable population does not necessarily remain fixed in size. It can be expanding or shrinking. The crude death rate as defined above and applied to a whole population can give a misleading impression. For example, the number of deaths per 1,000 people can be higher in developed nations than in less-developed countries, despite standards of health being better in developed countries. This

3854-553: The core of the data for any medical institution, such as patient and emergency contact information and patient medical record data. They allow for the identification of a patient and their categorization into categories for the purpose of statistical analysis. Patient demographics include: date of birth , gender , date of death , postal code, ethnicity, blood type , emergency contact information, family doctor, insurance provider data, allergies , major diagnoses and major medical history. Formal demography limits its object of study to

3936-498: The core of the discipline with many other methods borrowed from social or other sciences. Demographic research is conducted in universities, in research institutes, as well as in statistical departments and in several international agencies. Population institutions are part of the CICRED (International Committee for Coordination of Demographic Research) network while most individual scientists engaged in demographic research are members of

4018-528: The development of demography and to the toolkit of methods and techniques of demographic analysis. Demography is the statistical and mathematical study of the size, composition, and spatial distribution of human populations and how these features change over time. Data are obtained from a census of the population and from registries: records of events like birth , deaths , migrations, marriages, divorces , diseases, and employment . To do this, there needs to be an understanding of how they are calculated and

4100-649: The distribution and abundance of organisms. As it relates to organizations and demography, organizations go through various liabilities to their continued survival. Hospitals, like all other large and complex organizations are impacted in the environment they work. For example, a study was done on the closure of acute care hospitals in Florida between a particular time. The study examined effect size, age, and niche density of these particular hospitals. A population theory says that organizational outcomes are mostly determined by environmental factors . Among several factors of

4182-518: The environment. During the 15th and 16th centuries, statistics were a method for counting and listing populations and State resources. The term statistics comes from the Neo-Latin statisticum collegium (council of state) and refers to science of the state . According to the Organisation for Economic Co-operation and Development (OECD), official statistics are statistics disseminated by

4264-478: The exclusive use of the government. Moreover, they should be disseminated simultaneously. Users can be consulted by NSOs but the decisions should be made by statistical bodies. Information and activities of producers of official statistics should be independent of political control. Moreover, NSOs have to be free of any political interference that could influence their work and thus, the results. They should not make any political advice or policy-perspective comments on

4346-408: The family. The causes of turnover can be split into two separate factors, one linked with the culture of the organization, and the other relating to all other factors. People who do not fully accept a culture might leave voluntarily. Or, some individuals might leave because they fail to fit in and fail to change within a particular organization. A basic definition of population ecology is a study of

4428-520: The general public and the research community with a continuing flow of information (...). This bulk of data is usually called official statistics. Official statistics should be objective and easily accessible and produced on a continuing basis so that measurement of change is possible. Official statistics result from the collection and processing of data into statistical information by a government institution or international organization. They are then disseminated to help users develop their knowledge about

4510-579: The history of NVSS and how to prepare it for the next century. Libraries and other link collections have pointed to the NVSS as an official data source for the vital statistics of the United States . Official statistics Official statistics are statistics published by government agencies or other public bodies such as international organizations as a public good . They provide quantitative or qualitative information on all major areas of citizens' lives, such as economic and social development, living conditions, health , education , and

4592-565: The information system of a democratic society, serving the government, the economy and the public with data about the economic, demographic, social and environmental situation". The categorization of the domains of official statistics has been further developed in the Classification of Statistical Activities, endorsed by the Conference of European Statisticians and various other bodies. Statistical indicators provide an overview of

4674-418: The measurement of population processes, while the broader field of social demography or population studies also analyses the relationships between economic, social, institutional, cultural, and biological processes influencing a population. Demographic thoughts traced back to antiquity, and were present in many civilisations and cultures, like Ancient Greece , Ancient Rome , China and India . Made up of

4756-413: The nation will become a nation of immigrants. This influx is projected to rise over the next century as new immigrants and their children will account for over half the U.S. population. These demographic shifts could ignite major adjustments in the economy, more specifically, in labor markets. People decide to exit organizations for many reasons, such as, better jobs, dissatisfaction, and concerns within

4838-612: The national and at international levels. The production process of official statistics comprises 8 phases, as documented in the Generic Statistical Business Process Model (GSBPM): Even after they have been published, some official statistics may be revised. Policy-makers may need preliminary statistics quickly for decision-making purposes, but eventually it is important to publish the best available information, so official statistics are often published in several vignettes. In order to understand

4920-533: The national statistical office must protect the privacy of individual respondents, whether persons or businesses. But on the contrary, government units such as institutions cannot invoke statistical confidentiality. All respondents have to be informed about the purpose and legal basis of the survey and especially about the confidentiality measures. The statistical office should not release any information that could identify an individual or group without prior consent. After data collection, replies should go back directly to

5002-624: The national statistical system in countries where statistical production is de-centralized. These organizations are responsible for producing and disseminating official statistical information, providing the highest quality data. Quality in the context of official statistics is a multi-faceted concept, consisting of components such as relevance, completeness, timeliness, accuracy, accessibility, clarity, cost-efficiency, transparency, comparability and coherence. The core tasks of NSOs, for both centralized and decentralized systems, are determining user needs and filtering these for relevance. Then they transform

5084-470: The national statistical system, excepting those that are explicitly not to be official". Governmental agencies at all levels, including municipal, county , and state administrations, may generate and disseminate official statistics. This broader possibility is accommodated by later definitions. For example: Almost every country in the world has one or more government agencies (usually national institutes) that supply decision-makers and other users including

5166-458: The original data-collection procedures may prevent accurate evaluation of data quality. The demographic analysis of labor markets can be used to show slow population growth, population aging , and the increased importance of immigration. The U.S. Census Bureau projects that in the next 100 years, the United States will face some dramatic demographic changes. The population is expected to grow more slowly and age more rapidly than ever before and

5248-429: The phenomena or circumstances their own work is focusing on. For instance, those users will take some official statistics into consideration before launching a product, or deciding on a specific policy or on a marketing strategy . As with the general interest users, this group does not usually have a good understanding of statistical methodologies, but they need more detailed information than the general users. Users with

5330-528: The population. Demographic analysis estimates are often considered a reliable standard for judging the accuracy of the census information gathered at any time. In the labor force , demographic analysis is used to estimate sizes and flows of populations of workers; in population ecology the focus is on the birth, death, migration and immigration of individuals in a population of living organisms, alternatively, in social human sciences could involve movement of firms and institutional forms. Demographic analysis

5412-516: The prefix demo- and the suffix -graphy , the term demography refers to the overall study of population. In ancient Greece, this can be found in the writings of Herodotus , Thucydides , Hippocrates , Epicurus , Protagoras , Polus , Plato and Aristotle . In Rome, writers and philosophers like Cicero , Seneca , Pliny the Elder , Marcus Aurelius , Epictetus , Cato , and Columella also expressed important ideas on this ground. In

5494-627: The quality issues relating to non-response and survey errors. There are various survey methods that can be used such as direct interviewing, telephone, mail, online surveys. A census is a complete enumeration of a population or groups at a point in time with respect to well-defined characteristics (population, production). Data are collected for a specific reference period. A census should be taken at regular intervals in order to have comparable information available, therefore, most statistical censuses are conducted every 5 or 10 years. Data are usually collected through questionnaires mailed to respondents, via

5576-417: The quality of the accurate and timely results must be assessed prior to release. But if errors in the results occur before or after the data revision, they should be directly corrected and information should be disseminated to the users at the earliest possible time. Producers of official statistics have to set analytical systems in order to change or improve their activities and methods. All data collected by

5658-566: The questions they answer which are included in these four concepts: population change , standardization of population numbers, the demographic bookkeeping equation, and population composition. There are two types of data collection —direct and indirect—with several methods of each type. Direct data comes from vital statistics registries that track all births and deaths as well as certain changes in legal status such as marriage, divorce, and migration (registration of place of residence). In developed countries with good registration systems (such as

The NSO is in charge of the coordination between statistical producers and of ensuring the coherence and compliance of the statistical system to agreed standards. The NSO has a coordination responsibility as its President/Director General represents the entire national system of official statistics, both at

5822-713: The resulting data. In 2005, the United Nations Economic and Social Council adopted a resolution urging: "Member States to carry out a population and housing census and to disseminate census results as an essential source of information for small area, national, regional and international planning and development; and to provide census results to national stakeholders as well as the United Nations and other appropriate intergovernmental organizations to assist in studies on population, environment, and socio-economic development issues and programs". A register

5904-500: The results released at any time, even at press conferences or in interviews with the media. The need for transparency is essential for NSOs to gain the trust of the public. They have to expose to the public the methods they use to produce official statistics, and be accountable for all the decisions they take and the results they publish. Also, statistical producers should warn users of certain interpretations and false conclusions even if they try to be as precise as possible. Furthermore,

5986-417: The same sources of change. When dealing with ethnic groups, however, "net migration" might have to be subdivided into physical migration and ethnic reidentification ( assimilation ). Individuals who change their ethnic self-labels or whose ethnic classification in government statistics changes over time may be thought of as migrating or moving from one population subcategory to another. More generally, while

6068-447: The samples have been drawn in a nationally representative way, inferences can be drawn from these studies about the differences between four distinct generations of British people in terms of their health, education, attitudes, childbearing and employment patterns. Indirect standardization is used when a population is small enough that the number of events (births, deaths, etc.) are also small. In this case, methods must be used to produce

6150-701: The situation and the development trends in our society. Users can gather information making use of the services of the National Statistical Offices. They can easily find it on the agency's website. The development of computing technologies and the Internet has enabled users - businesses, educational institutions and households among others- to have access to statistical information. The Internet has become an important tool for statistical producers to disseminate their data and information. People are able to access information online. The supply of information from statistical agencies has increased. Today

6232-417: The social, demographic and economic structure of the society. Moreover, these indicators facilitate comparisons between countries and regions. For population , the main indicators concern demographics , such as: The gender statistics include: In the employment category: There are various indicators for the economy such as: For trade indicators we find: Environment indicators include: For

6314-611: The statistical producer, without involving any intermediary. Data processing implies that filled-in paper and electronic form with full names should be destroyed. The use of international standards at the national level aims to improve international comparability for national users and facilitate decision-making, especially when controversial. Moreover, the overall structure, including concepts and definitions, should follow internationally accepted standards, guidelines or good practices. International recommendations and standards for statistical methods approved by many countries provide them with
