Abstract copyright UK Data Service and data collection copyright owner.

The aggregate statistics produced as outputs from UK censuses provide information on a wide range of demographic and socio-economic characteristics of the population of the United Kingdom. They are predominantly a collection of aggregated, or summary counts of the numbers of people, families or households resident in specific geographical areas or 'zones' possessing particular characteristics, or combinations of characteristics drawn from the themes of population, people and places, families, ethnicity and religion, health, work, and housing.

Aggregate statistics are available for the full range of geographies employed within the census, from the smallest (output areas with an average of 150 persons in England and Wales), to national level. For further information about the geographies used in the output of census aggregate statistics, see the section on census geography in the Office for National Statistics' Beginner's Guide to UK Geography.
