Over time, our aim is to produce information on a range of topics such as property size (number of rooms and floor space), property type and overcrowding. Each year we aim to expand the breadth, depth and accuracy of our Research Outputs. This is dependent on the availability of the data and its statistical quality.

An Administrative Data Census could also bring additional benefits. We’re looking at the potential for combining administrative, survey and big data to produce new outputs such as housing affordability or fuel poverty, which are not currently provided by a 10-yearly census.
