Northern Ireland Labour Force Survey: Urban-Rural Statistics

The sample for each quarter consists of around 3,250 addresses, made up of five 'waves', each containing approximately 650 private households. Every sampled address is interviewed in five successive quarters, such that in any one quarter one wave will be receiving their first interview, one wave their second and so on. This results in an 80% sample overlap between quarters. Due to the cumulative effect of refusals and ineligible addresses, the number of 'active' addresses is approximately 2,700 each quarter.

More information on the survey is available from the DfE website, and from the Central Survey Unit.
