ONS have confirmed that the first small-area census outputs will be published on 2nd November at 9:30am.

What data will be released?

The first topic for release will be ‘Demography and Migration’.

A number of indicators will be published as part of 10 datasets on:

  • Usual residents
  • Legal partnership status
  • Country of birth (detailed and aggregate)
  • Passports held (detailed and aggregate)
  • Length of residence
  • Age of arrival in the UK
  • Migrants (from within and outside the UK)
  • Household composition
  • Households by deprivation dimensions
  • Living arrangements

In June, ONS published Local Authority level population figures. This release will also include small-area data and revised, non-rounded figures for Local Authority level data for:

  • Usual resident population by sex
  • Usual resident population by single year age group (previously released as 5 year age groups in June)
  • Usual resident population density
  • Number of households.

Based on the draft specification for Census 2021, we don’t think that small-area data for usual resident population by sex and single year age group combined will be published as part of this release. Multivariate data is due to be published early next year.

Which indicators are new for Census 2021?

Some indicators relate to new questions on the census form. In some cases, this means a slightly rephrased question to previous iterations. However, in all cases, it means there is not any directly comparable data for previous timepoints.

New indicators are likely to include:

  • Indicators on legal partnership status
  • Indicators on passports held for some aggregate regions
  • People that are not usual residents
  • Indicators on migrants
  • Indicators on multiple-family households.

When will this data be available in Local Insight?

We have been busy preparing for the small-area data release, including ensuring that the underlying geographies in Local Insight allow for new 2021 statistical geographies.

We aim to have the data in the system within three working days of release – and we are hopeful it will be sooner (the June release for local authority level data was available for use on the same day of publication).
