Transforming how we count the population

Statistically Speaking podcast

For the past 200 years the once-a-decade census has been the benchmark for measuring the number of people in the country, but do improvements in technology and greater availability of data now mean that change is on the horizon?  

In the latest episode of Statistically Speaking we discuss how the ONS has been working to transform the way we count the population, using new datasets to give more accurate, timely, and detailed measurements. We also look ahead to a major consultation exercise starting on June 29.
