84-465: Demographic features of the population of Zimbabwe include population density , ethnicity , education level, health of the populace, economic status, religious affiliations and other aspects of the population. The population of Zimbabwe has grown during the 20th century. This is in accordance with the model of a developing country with high birth rates and falling death rates, resulting in relatively high population growth rate (around 3% or above in

168-468: 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

252-685: A Malawian slave, known by the Swahili name Salimini, who had been captured in Malawi some ten years earlier. Salimini, who came from a place called Mphande apparently in the Lilongwe region, also noted some differences between his own dialect, which he called Kikamtunda , the "language of the plateau", and the Kimaravi dialect spoken further south; for example, the Maravi gave the name mombo to

336-401: 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

420-484: 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

504-460: 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

588-509: A pause in the middle of a sentence the speaker's voice tends to rise up; this rise is referred to as a boundary tone . Other intonational tones are sometimes heard, for example a rising or falling tone at the end of a yes-no question. Chewa nouns are divided for convenience into a number of classes, which are referred to by the Malawians themselves by names such as "Mu-A-", but by Bantu specialists by numbers such as "1/2", corresponding to

672-498: 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

756-509: A result, Tumbuka was removed from the school curriculum, the national radio, and the print media. With the advent of multi-party democracy in 1994, Tumbuka programmes were started again on the radio, but the number of books and other publications in Tumbuka remains low. Chewa is the most widely known language of Malawi , spoken mostly in the Central and Southern Regions of that country. It

840-426: 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

924-515: A substantial influx of emigrants from the United Kingdom—a handful previously resided in other colonies such as India, Pakistan and Kenya . Also represented on a much smaller scale were individuals of Afrikaner , Greek , and Portuguese origin. After Rhodesia's Unilateral Declaration of Independence in 1965, Ian Smith 's administration removed technical obstacles to immigration from southern Europe . A heavily urbanised Coloured population

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 ,

1092-448: A word like bambo 'father', even though it is singular, will take plural concords (e.g. bambo a nga akuyenda, ndiku wa ona 'my father is walking, I see him'); they note that to use the singular object-marker -mu- would be 'grossly impolite'. The various prefixes are shown on the table below: There are 17 different noun classes, but because some of them share concords there are in fact only 12 distinct sets of prefixes. In

1176-441: Is a useful demographic technique used in the analysis of a business. It can be used as an interpretive and analytic tool for the comparison of different markets. These organizations have interests about the number and characteristics of their clients so they can maximize the sale of their products, their outlook on their influence, or the ends of their power, services, and beneficial works. Chewa language Chewa belongs to

1260-777: Is also spoken in Eastern Province of Zambia , as well as in Mozambique , especially in the provinces of Tete and Niassa . It was one of the 55 languages featured on the Voyager spacecraft . The Chewa were a branch of the Maravi people who lived in the Eastern Province of Zambia and in northern Mozambique as far south as the River Zambezi from the 16th century or earlier. The name "Chewa" (in

1344-417: 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

Many, however, can also trace their ancestry to the Dutch/Khoisan mulatto clans of the Cape . With the exception of a select few who were brought to Zimbabwe as railroad workers, most Asians in Zimbabwe arrived from India pursuing employment or entrepreneurship . An educated class, they have traditionally engaged in retail trade or manufacturing. Zimbabwe has 16 official languages: Chewa , Chibarwe , English, Kalanga , Koisan , Nambya , Ndau , Ndebele , Shangani , Shona , sign language , Sotho , Tonga , Tswana , Venda , and Xhosa . English

1512-431: 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

1596-670: Is no prefix, or where the prefix is ambiguous, the concords (see below) are used as a guide to the noun class. For example, katúndu 'possessions' is put in class 1, since it takes the class 1 demonstrative uyu 'this'. Some nouns belong to one class only, e.g. tomáto 'tomato(es)' (class 1), mowa 'beer' (class 3), malayá 'shirt(s)' (class 6), udzudzú 'mosquito(es)' (class 14), and do not change between singular and plural. Despite this, such words can still be counted if appropriate: tomáto muwíri 'two tomatoes', mowa uwíri 'two beers', malayá amódzi 'one shirt', udzudzú umódzi 'one mosquito'. Class 11 (Lu-)

1680-476: Is not complete. The Population Department of the United Nations prepared the following estimates. Total Fertility Rate (TFR) (Wanted Fertility Rate) and Crude Birth Rate (CBR): Fertility data as of 2010-2011 (DHS Program): Life expectancy from 1950 to 2021 ( UN World Population Prospects ): According to 2012 Census report, 99.6% of the population is of African origin. Of the rest of the population,

1764-556: Is not found in Chewa. Words like lumo 'razor' and lusó 'skill' are considered to belong to class 5/6 (Li-Ma-) and take the concords of that class. Infinitive class: Locative classes: Pronouns, adjectives, and verbs have to show agreement with nouns in Chichewa. This is done by means of prefixes, for example: Class 2 (the plural of class 1) is often used for respect when referring to elders. According to Corbett and Mtenje,

1848-567: Is not obligatory in Chewa (for example, ndagula means 'I have bought (them)'). If used, it comes immediately before the verb root, and agrees with the object: The object infix of classes 16, 17, and 18 is usually replaced by a suffix: ndaonámo 'I have seen inside it'. The same infix with verbs with the applicative suffix -ira represents the indirect object, e.g. ndamúlembera 'I have written to him'. Numeral concords are used with numbers -módzi 'one', -wíri 'two', -tátu 'three', -náyi 'four', -sanu 'five', and

Besides Christianity, ancestral worship (Amadlozi) is the most practised non-Christian religion which involves ancestor worship and spiritual intercession. Under 1% of the population is Muslim , although many Zimbabweans are influenced by Abrahamic food laws. According to the United Nations World Health Organization , the average life expectancy for men in 2006

2016-403: Is only one high tone in a word (generally on one of the last three syllables), or none. However, in compound words there can be more than one high tone, for example: A second important use of tone is in the verb. Each tense of the verb has its own characteristic tonal pattern (negative tenses usually have a different pattern from positive ones). For example, the present habitual has high tones on

2100-550: 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

2184-404: Is that they are clusters. The consonant inventory under a cluster analysis is as follows: Consonants in parentheses are marginal or found mainly in loanwords. The lateral is an approximant [l] word-initially and a flap [𝼈] medially. If the more complex syllable onsets are analyzed as single consonants, the inventory is as follows: The spelling used here is that introduced in 1973, which

2268-473: 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

2352-554: 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

2436-503: Is the one generally in use in the Malawi at the present time, replacing the Chinyanja Orthography Rules of 1931. Notes on the consonants Like most other Bantu languages, Chewa is a tonal language; that is to say, the pitch of the syllables (high or low) plays an important role in it. Tone is used in various ways in the language. First of all, each word has its own tonal pattern, for example: Usually there

2520-432: 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

2604-510: 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

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

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

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

3276-666: 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

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

Since 1991, however, there has been a jump in death rates from a low of 10 per 1000 in 1985 to a high of 25 per 1000 in 2002/2003. It has since subsided to just under 22 per 1000 (estimate for 2007) a little below the birth rate of around 27 per 1000.

3528-544: The 2022 revision of the World Population Prospects, the population of Zimbabwe was estimated by the United Nations at 15,993,524 in 2021. About 38.9% comprised youths under 15, while another 56.9% grouped persons aged between 15 and 65 years. Only around 4.2% of citizens were apparently over 65.

The most straightforward analysis

3948-467: 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

4032-696: 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

4116-518: 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

English, Ndebele and Shona are given far more airtime. Christians comprise 85% of the Zimbabwean population. Of that number, 61% regularly attend Christian churches . The largest Christian churches are Anglican, Roman Catholic, Seventh Day Adventist and Methodist. However, like most former European colonies , Christianity

However, irregular pairings are also possible, especially with loanwords; for example, bánki 'bank', which takes the concords of class 9 in the singular, has a plural mabánki (class 6). When assigning nouns to a particular class, initially the prefix of the noun is used. Where there

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

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

4620-649: 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

4704-596: The examples below, the concords are illustrated mainly with nouns of classes 1 and 2. The shortened forms are more common. Prefixed by a supporting vowel, or by ná 'with' or ndi 'it is', these make the pronouns 'he/she' and 'they': For classes other than classes 1 and 2, a demonstrative is used instead of a freestanding pronoun, for example in class 6 ichi or icho . But forms prefixed by ná- and ndi- such as nácho and ndichó are found. The three pronominal adjectives yénse 'all', yékha 'alone', yémwe 'that same' (or 'who') have

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

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

Vowels are generally lengthened in the penultimate syllable of a prosodic phrase. Chewa consonants can be simple (directly preceding a vowel) or may be followed by w or y : In the orthography, the place of by is taken by

5544-528: 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
