This document discusses the Scottish Index of Multiple Deprivation (SIMD), which is used to identify relatively deprived areas in Scotland. The SIMD ranks small areas from most to least deprived based on indicators like income, employment, health, education, crime, and housing. It is a relative measure that compares deprivation between areas but does not measure absolute deprivation levels or change over time. While SIMD helps identify issues in deprived areas, not all individuals in those areas are deprived and some deprived people live outside of deprived areas.
