The Scottish Indices of Multiple Deprivation (SIMD) 2004, 2006 and 2009 identify small area concentrations of multiple deprivation across Scotland. Small areas, called datazones, are ranked from 1 (most deprived) to least deprived. The ranking is based on information covering a number of different types or 'domains' of deprivation; income, employment, health, education, access to services, housing and crime (not 2004). Further information is available from the Scottish Government’s SIMD web pages.
