This is a summary of main topics covered by the results of the 2001 Census. There are also many figures which relate one topic to another.

They are listed as topics covered directly by questions on the Census forms and by topics derived during processing. There is also brief guidance on who or what is counted.

The topics are based on the questions on the Census form and by the categories to tick. Further categories are created by coding 'write in' responses when the forms are processed. There are results on the subject of each question, and on a number of further topics which are derived in processing from the direct responses to two or more questions.

All figures relate to 'population bases' - the units counted in a table. The most common unit is a person, but there are also bases of people grouped into households. The Census is also about housing, and there are further bases such as dwellings or communal establishments. Some questions and figures apply only to part of the population, for example questions about employment to those aged sixteen or over.

The 2001 Census counted people where they were usually resident, with very few exceptions. The vast majority of results are on this usual residence base, although there are figures about people where they work and where they lived a year before the Census (migration).
