To collect data that are representative of the British general population, Natsal uses the Postcode Address File as its sampling framework. This is where postcodes, then households, are selected at random. An interviewer from NatCen Social Research then calls at the selected household and invites one person in the eligible age-range to take part. For Natsal-4, that’s people aged between 16-59.
Whilst you can't just sign up to take part in Natsal, there are other ways to engage with the study. For example, as part of the development work for Natsal-4 we held an open consultation so people from all walks of life could have their say on the questions that the Natsal-4 survey should ask.
