Background: Following the global financial crisis in 2007/08, the UK implemented an austerity programme which may impact on services. Scotland comprises both densely populated urban conurbations and highly dispersed remote rural and island communities. Method: Expenditure data were extracted from Scottish Government statistics. Per capita expenditure was calculated using adjusted Scotland's 2011 census data. Results: There was a 3.41% decrease in real term expenditure on adult intellectual disabilities services between 2012/13 and 2014/15 (>£32 million). In 2014/15, per capita expenditure on adult intellectual disabilities health care ranged from £1,211 to £17,595; social care from £21,147 to £83,831; and combined health and social care expenditures from £37,703 to £85,929. Per capita expenditure on combined health and social care was greater in rural areas, with more on intellectual disabilities social care, though less on health care. Conclusions: Scottish expenditure on adult intellectual disabilities services has not kept abreast of rising living costs. It varies considerably across the country: a postcode lottery.
