ONS considers 'radical census shake-up'

The Office for National Statistics is consulting on changes to the census.
In the future, they suggest, it could become a mostly online exercise or ditched in its current form completely.
One option could be to take its information from the records of other government departments and agencies, such as the NHS or HMRC.
Glen Watson, director of the ONS, told the Today programme's Evan Davis that they want to come up with "the best results for the future".
