A topic summary is a set of data and supporting commentary, grouped by a similar theme. The majority of the datasets that we will release as part of each topic summary will contain data about just one variable.
From autumn to winter 2022, we plan to release topic summaries in a staggered approach, every two to three weeks, in the following order:
demography and migration
ethnic group, national identity, language, and religion
health, disability, and unpaid care
labour market and travel to work
sexual orientation and gender identity
UK armed forces veterans
Each of these datasets will contain information about the usual resident population of England and Wales. These datasets will not contain totals or subtotals.
Initially, we aim to make the topic summary datasets available down to Output Area (OA) level. As soon as it is practical, we plan to provide these datasets 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 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 will create these dynamic area profiles using data from the topic summaries. As we release more data from the topic summaries over time, the area profiles will develop to allow users to view more statistics for a particular area.
We aim to make area profiles available for a range of area types over time, starting initially with local authorities and wards. These area profiles are similar in concept to those available within Nomis area reports.
The variables and classifications to be included
We have detailed the variables and classifications we plan to include in the topic summaries and area profiles in the corresponding tabs of the Topic summaries and area profile specifications spreadsheet.
We are in the process of finalising these specifications. This spreadsheet represents our plans as of March 2022 and we will update it in summer 2022, as more information is confirmed.
Where to find the data
We will publish topic summary datasets and area profiles on the ONS website. Topic summary datasets will also be available from the Nomis website.
