Census Transformation Programme

Looking ahead to 2021 and beyond, the ONS has established a Census Transformation Programme. Its aim is to make the best use of all available data in England and Wales to enhance the provision of population statistics. It will:-

• provide an online census in 2021,
• seek to increase the use of administrative data to enhance population statistics,
• form plans for the provision of population statistics after 2021.

Updates on progress are published from time to time on the Census Transformation Programme website.

For example, the ONS have carried out extensive research into the use of administrative data (such as those held by the DWP, NHS Patient Registers and School Census) to generate unofficial estimates of local population sizes.

In November 2016, this methodology provided retrospective estimates for Somerset which are higher than the 2011 Census and 2015 mid-year estimates. More work is being done to understand the differences. However, there is evidence that higher estimates are often found in areas, such as Somerset, with relatively high numbers of seasonal workers, residential schools and people contacting administrative services (eg health and social care).
