You asked

I wanted to know if I could have any latest 16+ population estimates that you may have, or are currently working on, for the current electoral wards, as proposed by the LGBCE in England, and the Local Democracy and Boundary Commission for Wales in Wales.

Some of the existing Census 2021 data that can be queried on the Nomis website has old, out-of-date electoral wards, and also does not give any information on the ward's corresponding local authority area, ITL1 Region, or Ceremonial County.

We said

Thank you for your freedom of information request. 

The most up-to-date population by age (16+) data, at ward level, is from Census 2021 and is available here

Our ONS Geography Portal contains look-ups, including Ward to Local Authority District to County to Region to Country (May 2023) Lookup in United Kingdom 

A list of the latest (2023) wards is also available in the associated download. 

Population estimates by output areas, electoral, health and other geographies, England and Wales: mid-2021 and mid-2022, which includes wards, was published on 19 March.   

You may be interested in our data for Westminster parliamentary constituencies. Data is available for as they currently stand, which uses the 2010 boundaries. Also, we released some census data for the new boundaries on 28 November 2023.
