Topic summaries

A topic summary is a set of data and supporting information, grouped by a similar theme. The majority of the datasets that we have released as part of each topic summary contain data about just one variable.

Topic summaries in publication order are:

Each of these datasets contain information about the usual resident population of England and Wales. These datasets do not contain totals or subtotals. 

The topic summary datasets are available down to Output Area (OA) level, where statistical disclosure control allows. Where possible, datasets are available for other geographies, using the OA best-fit approach.  Output Areas are the smallest geography for which we will make the standard outputs available. These are generally around 100 households in size.

Area profiles

Area profiles allow users to view statistics from across different topics for a particular area. These also allow users to compare local statistics for an area against national statistics.

We have created these dynamic area profiles using data from the topic summaries.

Area profiles are available for a range of area types over time. You can view area profiles on the Nomis website.

The variables and classifications to be included

We have detailed the variables and classifications included in the topic summaries in the corresponding tabs of the Topic summaries specifications spreadsheet (259kB, xlsx)

Where to find the data

We have published the topic summary datasets on the ONS website. Topic summary datasets are also available from the Nomis website.
