  Quality information: There are quality considerations about higher education qualifications, including those at Level 4+, responses from older people and international migrants, and comparability with 2011 Census data. 

  Comparability with 2011: Broadly comparable The categories for this variable are the same as the ones in the 2011 Census. However, in Census 2021 the question was revised and split up to group together different qualifications. This means that the way people answered the question in Census 2021 cannot be fully compared with the answers from the 2011 Census. For example, some people who hold an older or non-UK qualification when answering the question in Census 2021 may have chosen a higher qualification level than they did in the 2011 Census, although they hold the same qualifications.
