The census was a kind of therapy to lift us out of our lockdown gloom, according to one of the country's most prominent sociologists.Dr Liz Allen of the Australian National University said she thought that the collective act of filling in the forms and revealing a bit about ourselves helped answer that need in a time when we are isolated and locked down.This week, Alex Crowe and Steve Evans talk with Dr Allen and the Centre for Public Christianity's Dr Mark Stephens about what we could learn from this year's census.
