The Office for National Statistics’ deputy national statistician Pete Benton said: “Ultimately, the full suite of census results, based on the information we all gave, will ensure decisions about how the billions of pounds we spend each year as a nation are made using the best possible evidence.
"This includes planning our emergency services, mental health care, school places, hospital beds, houses, roads, buses, trains, trams, GPs and dentists’ services."
Data from the 2021 census for England and Wales will be published in stages over the next two years, the ONS said.
