Intercensal Estimate
In demographics, an intercensal estimate is an estimate of population between official census dates with both of the census counts being known. Some nations produce regular intercensal estimates while others do not. Intercensal estimates can be less or more informative than official census figures, depending on methodology, completeness, accuracy (as they can have significant undercounts or overestimates) and date of data, and can be released by nations, subnational entities, or other organizations including those not affiliated with governments. They differ from population projections as they are from past dates, although intercensal estimates can be used to form population projections. Postcensal estimate Intercensal estimates are one of the two types of population estimates, the other being ''postcensal estimates''. Intercensal estimates are considered to be more accurate than postcensal estimates, because they approximated between two dates with the ''exact'' figure (accou ...

Demography
Demography () 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 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 the population. Demographic analysis estima ...

Census
A census (from Latin ''censere'', 'to assess') is the procedure of systematically acquiring, recording, and calculating population information about the members of a given Statistical population, population, usually displayed in the form of statistics. This term is used mostly in connection with Population and housing censuses by country, national population and housing censuses; other common censuses include Census of agriculture, censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications, and other useful information to coordinate international practices. The United Nations, UN's Food ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methodology
In its most common sense, methodology is the study of research methods. However, the term can also refer to the methods themselves or to the philosophical discussion of associated background assumptions. A method is a structured procedure for bringing about a certain goal, like acquiring knowledge or verifying knowledge claims. This normally involves various steps, like choosing a Sample (statistics), sample, Data collection, collecting data from this sample, and interpreting the data. The study of methods concerns a detailed description and analysis of these processes. It includes evaluative aspects by comparing different methods. This way, it is assessed what advantages and disadvantages they have and for what research goals they may be used. These descriptions and evaluations depend on philosophical background assumptions. Examples are how to conceptualize the studied phenomena and what constitutes evidence for or against them. When understood in the widest sense, methodology al ...

Nations
A nation is a type of social organization where a collective identity, a national identity, has emerged from a combination of shared features across a given population, such as language, history, ethnicity, culture, territory, or society. Some nations are constructed around ethnicity (see ethnic nationalism) while others are bound by political constitutions (see civic nationalism). A nation is generally more overtly political than an ethnic group. Benedict Anderson defines a nation as "an imagined political community �� imagined because the members of even the smallest nation will never know most of their fellow-members, meet them, or even hear of them, yet in the minds of each lives the image of their communion", while Anthony D. Smith defines nations as cultural-political communities that have become conscious of their autonomy, unity and particular interests. '' Black's Law Dictionary'' also defines nation as a community of people inhabiting a defined territo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subnational Entities
Administrative divisions (also administrative units, administrative regions, subnational entities, or constituent states, as well as many similar generic terms) are geographical areas into which a particular independent sovereign state is divided. Such a unit usually has an administrative authority with the power to take administrative or policy decisions for its area. Administrative divisions are often used as polygons in geospatial analysis. Description Usually, sovereign states have several levels of administrative division. Common names for the principal (largest) administrative divisions include: states (subnational states, rather than sovereign states), provinces, lands, oblasts and regions. These in turn are often subdivided into smaller administrative units known by names such as comarcas, raions or districts, which are further subdivided into municipalities, communes or communities constituting the smallest units of subdivision (the local governments). Some admini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Projection
A population projection, in the field of demography, is an estimate of a future population. It is usually based on current population estimates derived from the most recent census plus a projection of possible changes based on assumptions of future births, deaths, and any migration into or out of the region being studied. Population projections are used by businesses, governments, and other program planners to assess future demand for consumer products, basic resources such as energy, water, and food, as well as services such as childcare, education, and care for the elderly. Governments and organizations make population projections for their own countries. In addition, organizations like the Population Division of the United Nations Department of Economic and Social Affairs, the US Census Bureau, and The Population Reference Bureau, develop their own projections. To make these projections they make assumptions about future values of fertility, mortality, and migration. Differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Margin Of Error
The margin of error is a statistic expressing the amount of random sampling error in the results of a Statistical survey, survey. The larger the margin of error, the less confidence one should have that a poll result would reflect the result of a simultaneous census of the entire Statistical population, population. The margin of error will be positive whenever a population is incompletely sampled and the outcome measure has positive variance, which is to say, whenever the measure ''varies''. The term ''margin of error'' is often used in non-survey contexts to indicate observational error in reporting measured quantities. Concept Consider a simple ''yes/no'' poll P as a sample of n respondents drawn from a population N \text(n \ll N) reporting the percentage p of ''yes'' responses. We would like to know how close p is to the true result of a survey of the entire population N, without having to conduct one. If, hypothetically, we were to conduct a poll P over subsequent sample ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
