'Deprivation Decile' is the Index of Multiple Deprivation (SIMD in Scotland and IMD for the rest of the UK) of the area in which the modelled house is located. It is a measure of the socio-economic characteristics of an area. '1' represents the most deprived areas and '10' the least deprived. For Scotland, an interactive SIMD map is available at simd.scot and for England, at dclgapps.communities.gov.uk/imd/idmap.html. 

SIMD/IMD influences household characteristics, in particular those related to employment and, therefore, daytime occupancy.
