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 Local Authority District (LAD) estimates of the median straight-line distances of all known residential moves to, from and within each LAD 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 LADs extend what is available from decennial census data. Median annual LAD residential move data are provided for adult individuals moving out of, moving into, or moving within each UK LAD. Estimates are triangulated with census estimates and can be used to update them during intercensal periods.

Note: The unit of DORM is in kilometres, and '*' means the figures were suppressed to avoid disclosing issues (i.e., lower count). For further info about how this was constructed, data source details etc, please see the data profile PDFs in the LSOA version here DoRM index (LSOA)
