82-501: Demographic features of the population of Uganda include population density , ethnicity , education level, health of the populace, economic status, religious affiliations and others. According to the 2022 revision of the World Population Prospects the total population was 45,853,778 in 2021, compared to only 5,158,000 in 1950. The proportion of children below the age of 15 in 2015 was 48.1 percent, 49.4 percent

164-468: 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

246-421: A V- syllable at the start). In other words, a strong claim for this language family is that almost all words end in a vowel, precisely because closed syllables (CVC) are not permissible in most of the documented languages, as far as is understood. This tendency to avoid consonant clusters in some positions is important when words are imported from English or other non-Bantu languages. An example from Chewa :

328-401: 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

410-668: A designation referring indiscriminately to language, culture, society, and race"." The Bantu languages descend from a common Proto-Bantu language , which is believed to have been spoken in what is now Cameroon in Central Africa . An estimated 2,500–3,000 years ago (1000 BC to 500 BC), speakers of the Proto-Bantu language began a series of migrations eastward and southward, carrying agriculture with them. This Bantu expansion came to dominate Sub-Saharan Africa east of Cameroon, an area where Bantu peoples now constitute nearly

492-414: A distant third place with 8.2 million speakers ( South Africa and Zimbabwe ), and Shona with less than 10 million speakers (if Manyika and Ndau are included), while Sotho-Tswana languages ( Sotho , Tswana and Pedi ) have more than 15 million speakers (across Botswana , Lesotho , South Africa, and Zambia ). Zimbabwe has Kalanga, Matebele, Nambiya, and Xhosa speakers. Ethnologue separates

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

656-498: 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

738-426: 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

820-405: 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 the population. Demographic analysis estimates are often considered a reliable standard for judging

902-499: 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 ,

Most native speakers of Swahili live in Tanzania , where it is a national language, while as a second language, it is taught as a mandatory subject in many schools in East Africa, and is a lingua franca of the East African Community . Other major Bantu languages include Lingala with more than 20 million speakers ( Congo , DRC ), followed by Zulu with 13.56 million speakers ( South Africa ), Xhosa at

1066-460: 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. Bantu languages The total number of Bantu languages

1148-417: 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

1230-497: Is estimated at between 440 and 680 distinct languages, depending on the definition of "language" versus "dialect" . Many Bantu languages borrow words from each other, and some are mutually intelligible . Some of the languages are spoken by a very small number of people, for example the Kabwa language was estimated in 2007 to be spoken by only 8500 people but was assessed to be a distinct language. The total number of Bantu speakers

1312-564: Is estimated to be around 350 million in 2015 (roughly 30% of the population of Africa or 5% of the world population ). Bantu languages are largely spoken southeast of Cameroon , and throughout Central , Southern , Eastern , and Southeast Africa . About one-sixth of Bantu speakers , and one-third of Bantu languages, are found in the Democratic Republic of the Congo . The most widely spoken Bantu language by number of speakers

Simplified phylogeny of northwestern branches of Bantu by Grollemund (2012): A40-50-60-70: Basaa languages , Bafia languages , Mbam languages , Beti language A10-20-30: Sawabantu languages , Manenguba languages A80-90: Makaa–Njem languages B20: Kele languages B10: Myene language B30: Tsogo languages C10-20-30: Ngondi–Ngiri languages , Mboshi languages , Bangi–Ntomba languages C40-D20-D32: Bati–Angba languages , Lega–Binja languages , Bira language B80-C60-70-80: Boma–Dzing languages , Soko languages , Tetela languages , Bushoong languages B40-H10-30-B50-60-70: Sira languages , Kongo languages , Yaka languages , Nzebi languages , Mbete languages , Teke languages L10-H40: Pende languages , Hungana language C50-D10: Soko languages , Lengola language D10-20-30-40-JD50: Mbole–Enya languages , Komo–Bira languages , Shi–Havu languages Other computational phylogenetic analyses of Bantu include Currie et al. (2013), Grollemund et al. (2015), Rexova et al. 2006, Holden et al., 2016, and Whiteley et al. 2018. Glottolog ( 2021 ) does not consider

1476-666: Is likely the innovative line cladistically . Northwest Bantu is not a coherent family, but even for Central Bantu the evidence is lexical, with little evidence that it is a historically valid group. Another attempt at a detailed genetic classification to replace the Guthrie system is the 1999 "Tervuren" proposal of Bastin, Coupez, and Mann. However, it relies on lexicostatistics , which, because of its reliance on overall similarity rather than shared innovations , may predict spurious groups of conservative languages that are not closely related . Meanwhile, Ethnologue has added languages to

1558-431: 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

1640-548: Is mainly geographic. The term "narrow Bantu" was coined by the Benue–Congo Working Group to distinguish Bantu as recognized by Guthrie, from the Bantoid languages not recognized as Bantu by Guthrie. In recent times, the distinctiveness of Narrow Bantu as opposed to the other Southern Bantoid languages has been called into doubt, but the term is still widely used. There is no true genealogical classification of

1722-550: 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

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

1886-459: Is the extensive use of affixes (see Sotho grammar and Ganda noun classes for detailed discussions of these affixes). Each noun belongs to a class , and each language may have several numbered classes, somewhat like grammatical gender in European languages. The class is indicated by a prefix that is part of the noun, as well as agreement markers on verb and qualificative roots connected with

1968-432: 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

2050-510: 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

2132-421: 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

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

2624-589: The Uganda Protectorate period, the British colonialists used South Asian immigrants as intermediaries. Following independence they constituted the largest non-indigenous ethnic group in Uganda, at around 80,000 people, and they dominated trade, industry, and the professions. This caused resentment among the native African majority, which was exploited by post-Independence leaders. After Idi Amin came to power in 1971 , he declared "economic war" on

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

2788-666: 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

2870-433: 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

Until recently most attempted classifications only considered languages that happen to fall within traditional Narrow Bantu, but there seems to be a continuum with the related languages of South Bantoid. At a broader level, the family is commonly split in two depending on the reflexes of proto-Bantu tone patterns: many Bantuists group together parts of zones A through D (the extent depending 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

This has been criticized for sowing confusion in one of the few unambiguous ways to distinguish Bantu languages. Nurse & Philippson (2006) evaluate many proposals for low-level groups of Bantu languages, but

3444-425: 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

The two groups have been described as having mirror-image tone systems: where Northwest Bantu has a high tone in a cognate, Central Bantu languages generally have a low tone, and vice versa. Northwest Bantu is more divergent internally than Central Bantu, and perhaps less conservative due to contact with non-Bantu Niger–Congo languages; Central Bantu

3690-467: 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

3772-609: The beginning of a syllable can be readily observed in such languages as Shona, and the Makua languages . With few exceptions, such as Kiswahili and Rutooro , Bantu languages are tonal and have two to four register tones. Reduplication is a common morphological phenomenon in Bantu languages and is usually used to indicate frequency or intensity of the action signalled by the (unreduplicated) verb stem. Well-known words and names that have reduplication include: Repetition emphasizes

3854-696: 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

3936-518: 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

4018-483: The concept of "language". In addition, delegates at the African Languages Association of Southern Africa conference in 1984 reported that, in some places, the term Kintu has a derogatory significance. This is because kintu refers to "things" and is used as a dehumanizing term for people who have lost their dignity. In addition, Kintu is a figure in some mythologies. In the 1990s,

4100-553: 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

4182-498: 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

4264-528: 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

4346-649: 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

4428-498: The entire population. Some other sources estimate the Bantu Expansion started closer to 3000 BC. The technical term Bantu, meaning "human beings" or simply "people", was first used by Wilhelm Bleek (1827–1875), as the concept is reflected in many of the languages of this group. A common characteristic of Bantu languages is that they use words such as muntu or mutu for "human being" or in simplistic terms "person", and

4510-408: 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.

4674-525: 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 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

4756-426: The largely mutually intelligible Kinyarwanda and Kirundi , which together have 20 million speakers. The similarity among dispersed Bantu languages had been observed as early as the 17th century. The term Bantu as a name for the group was not coined but "noticed" or "identified" (as Bâ-ntu ) by Wilhelm Bleek as the first European in 1857 or 1858, and popularized in his Comparative Grammar of 1862. He noticed

4838-445: The larger ethnolinguistic phylum named by 19th-century European linguists. Bleek's identification was inspired by the anthropological observation of groups frequently self-identifying as "people" or "the true people" (as is the case, for example, with the term Khoikhoi , but this is a kare "praise address" and not an ethnic name). The term narrow Bantu , excluding those languages classified as Bantoid by Malcolm Guthrie (1948),

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 verb has a number of prefixes, though in the western languages these are often treated as independent words. In Swahili , for example, Kitoto kidogo kimekisoma (for comparison, Kamwana kadoko karikuverenga in Shona language ) means 'The small child has read it [a book]'. kitoto 'child' governs

Guthrie reconstructed both the phonemic inventory and the vocabulary of Proto-Bantu. The most prominent grammatical characteristic of Bantu languages

5330-458: 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

5412-407: The plural prefix for human nouns starting with mu- (class 1) in most languages is ba- (class 2), thus giving bantu for "people". Bleek, and later Carl Meinhof , pursued extensive studies comparing the grammatical structures of Bantu languages. The most widely used classification is an alphanumeric coding system developed by Malcolm Guthrie in his 1948 classification of the Bantu languages. It

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

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

For instance, "Mwenda pole hajikwai," means "He who goes slowly doesn't trip," while, "Pole pole ndio mwendo," means "A slow but steady pace wins the race." The latter repeats "pole" to emphasize the consistency of slowness of the pace. As another example, "Haraka haraka" would mean "hurrying just for the sake of hurrying" (reckless hurry), as in "Njoo! Haraka haraka" [come here! Hurry, hurry]. In contrast, there are some words in some of
