Derived variables: environment

One of the strengths of the ONS Longitudinal Study (LS) is the ability to add geographical and environmental data to the database. These data can be combined with individual level data in order to describe the characteristics of where people live or to estimate their potential exposure to a given factor. Environmental variables are usually measured around census time points and merged into the database using geographical identifiers for the place of usual residence of LS sample members.

Some notes on environmental indicators which have been used with the LS can be found in the Geography Training Module and the Socio-Economic Status Training Module.

Applied to cases from:
1971 Census (selected urban areas only) Air and water quality
