9. The base population by ethnicity for 2011-12 is drawn from the 2011 Census (see footnote 8). For subsequent years, ethnic group sizes are drawn from the pooled sample of Scottish Surveys Core Questions (SSCQ) and therefore have an associated margin of error provided in the "range" column of Table 2.

Using SSCQ data makes it possible to control for the increasing age (into adulthood) of those youngest minority ethnic populations when the census was taken in 2011.

In both cases, population rates are based only on populations aged 16 or over, due to the SSCQ's methodology:
