Since its inception in 2004, there have been five revisions to the Scottish Index of Multiple Deprivation (SIMD), in 2006, 2009, 2012, 2016 and 2020. Analysis of changes in the overall ranking of data zones between revisions highlight changing patterns in the distribution of relative deprivation in Scotland. 

Despite Glasgow having the highest concentrations of deprivation in Scotland, in successive revisions, Glasgow’s position relative to other areas has improved. The proportion of Glasgow’s population who live in the most deprived decile nationally had dropped from 46% (in SIMD 2004) to 29% (in SIMD 2020).


SIMD – Scottish Index of Multiple Deprivation provides a relative measure of deprivation based on indicators from 7 domains – income, employment, health, education, access, housing, crime. The index identifies multiple deprivation for 6505 small areas (data zones) across Scotland.  There have been six versions of SIMD to date. The initial index of 2004 (SIMD 2004) has been revised five times in 2006 (SIMD 2006), 2009 (SIMD 2009), 2012 (SIMD 2012), 2016 (SIMD 2016) and 2020 (SIMD 2020).

Deprivation deciles - the term ‘deprivation decile’ is used to represent 10% of a population with a particular level of deprivation. Thus, the most deprived decile equates to the most deprived 10% within a population, while the least deprived decile represents the 10% of a population living in the least deprived circumstances.
