                 (c) stands for census results, and 

                (m) stands for official mid-year estimates.

**Figures for Ireland up to 1920 include Northern Ireland, after 1920 they are only for Southern Ireland. 

***Ireland figures for 2010, 2020, 2030, 2040, 2050

N.B. All UK figures collected from 1981 are those which have been recalculated in line with the results of the 2001 Census, therefore there may be some slight discrepancy between the figures for 1971 and 1981.

This version of the table produced July 2003, further details to be supplied.
