SURVEY OPTIONS

Address Register and Survey

Data from an address register is combined with a survey to estimate the population and its characteristics.  In its simplest form, the average number of people living at each address included in the survey is multiplied by the number of addresses in an area to give an estimate of the population in that area.  Estimates could be updated on an annual basis, but a longer time period may be required to produce estimates for smaller geographic areas.  Careful stratification can be used to increase the quality of estimates but this approach is very sensitive to the quality and consistency of the address register and local variations in household size.  Administrative sources or a specific coverage survey would be used for quality assurance, or to supplement survey data to produce small area estimates.
