The index data are compiled from CDRC Secure data Linked Consumer Registers, which contain annual updates of the names and addresses for adults in the UK from 1997 onwards. These data are used to provide yearly Lower layer Super Output Area (LSOA) estimates of the median straight-line distances of all known residential moves to, from and within each LSOA in the UK.
These data allow researchers to explore locality scale changes in residential mobility and migration patterns over an extended time period. The annual estimates and attribution of origins and destinations to specific LSOAs extend what is available from decennial census data. Median annual LSOA residential move data are provided for adult individuals moving out of, moving into, or moving within each UK LSOA. Estimates are triangulated with census estimates and can be used to update them during intercensal periods.
