词条 | Intercensal estimate |
释义 |
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.[1] Postcensal estimateIntercensal 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 (accounting for errors) being known and being considered factual.[2] Additionally, postcensal estimates can be based on the prior census. (e.g. a 2011 postcensal estimate can be based on a 2000 census, due to time and complexity of producing estimates from 2010 census data.). Intercensal surveyAll counts are estimates, including censuses (in reality every survey has a margin of error, even most census counts are corrected for data omission, duplication, cheating, miscounts) but some counts include random sampling (door to door and/or by calling) of actual residents rather than just producing figures based on mathematical models. These counts are called intercensal surveys. American Community Survey is one of these in the USA, where a percentage of residents are called and asked to participate in a census-like questionnaire. The topics covered may differ from the census forms, even if population figures are produced for both. By country{{section incomplete|date=August 2017}}
