Census Day is 21st March 2021. Ever wondered why we do a Census? The Census is a survey about all the households in England and Wales and occurs every 10 years. In this podcast, Jo speaks to Professor David Martin, a Professor of Geography at the University of Southampton. David has been heavily involved in the nationwide survey for nearly 40 years and is quite the celebrity within the Census world. Listen as Jo and David discuss how Covid and Brexit will effect this years data as well as how your answers determine what's in your local corner shop.
