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 (account ...

Demography
Demography () is the statistics, statistical study of populations, especially human beings. Demographic analysis examines and measures the dimensions and Population dynamics, 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 actions, social actors can change across time through processes of birth, death, and Human migration, migration. In the context of human biological populations, demographic analysis uses Public records, administrative records to develop an independent Approximation, estimate of the population. Demographic analysis estimates are often considered a reliable stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include 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 co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

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. In the context of research, this goal is usually to discover new knowledge or to verify pre-existing knowledge claims. This normally involves various steps, like choosing a sample, collecting data from this sample, and interpreting this data. The study of methods involves a detailed description and analysis of these processes. It includes evaluative aspects by comparing different methods to assess their advantages and disadvantages relative to different research goals and situations. This way, a methodology can help make the research process efficient and reliable by guiding researchers on which method to employ at each step. These descriptions and evaluations of methods often depend on philosophical background ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nations
A nation is a community of people formed on the basis of a combination of shared features such as language, history, ethnicity, culture and/or society. A nation is thus the collective identity of a group of people understood as defined by those features. Some nations are equated with ethnic groups (see ethnic nationalism) and some are equated with affiliation to a social and political constitution (see civic nationalism and multiculturalism). A nation is generally more overtly political than an ethnic group. A nation has also been defined as a cultural-political community that has become conscious of its autonomy, unity and particular interests. The consensus among scholars is that nations are socially constructed and historically contingent. Throughout history, people have had an attachment to their kin group and traditions, territorial authorities and their homeland, but nationalism – the belief that state and nation should align as a nation state – did not become a promine ...

Subnational Entities
Administrative division, administrative unit,Article 3(1). country subdivision, administrative region, subnational entity, constituent state, as well as many similar terms, are generic names for geographical areas into which a particular, independent sovereign state (country) is divided. Such a unit usually has an administrative authority with the power to take administrative or policy decisions for its area. Usually, the countries have several levels of administrative divisions. The common names for the principal (largest) administrative divisions are: states (i.e. "subnational states", rather than sovereign states), provinces, lands, oblasts, governorates, cantons, prefectures, counties, regions, departments, and emirates. These, in turn, are often subdivided into smaller administrative units known by names such as circuits, counties, ''comarcas'', raions, '' județe'', or districts, which are further subdivided into the municipalities, communes or communities constitu ...

Population Projection
Population projection, in the field of demography, is an estimate of a future population. In contrast with intercensal estimates and censuses, which usually involve some sort of field data gathering, projections usually involve mathematical models based only on pre-existing data may be made by a governmental organization, or by those unaffiliated with a government.

Margin Of Error
The margin of error is a statistic expressing the amount of random sampling error in the results of a survey. The larger the margin of error, the less confidence one should have that a poll result would reflect the result of a census of the entire 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, 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 poll P over subsequent samples of n respondents (newly drawn from N), we would expect those subs ...

American Community Survey
The American Community Survey (ACS) is a demographics survey program conducted by the U.S. Census Bureau. It regularly gathers information previously contained only in the long form of the decennial census, such as ancestry, citizenship, educational attainment, income, language proficiency, migration, disability, employment, and housing characteristics. These data are used by many public-sector, private-sector, and not-for-profit stakeholders to allocate funding, track shifting demographics, plan for emergencies, and learn about local communities. Sent to approximately 295,000 addresses monthly (or 3.5 million per year), it is the largest household survey that the Census Bureau administers. The American Community Survey gathers information annually in the 50 U.S. states, the District of Columbia, and Puerto Rico — however it does not gather information in four major U.S. territories (American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands).http://www3. ...
