This cross-sectional survey investigates political attitudes and voting behaviour in the 2022 Northern Ireland Assembly Election. It provides evidence on vote choice and people's attitudes towards a range of topics, including the Ireland/Northern Ireland Protocol, a possible referendum on Northern Ireland staying in the UK versus joining a united Ireland, and Northern Ireland's devolved institutions. The main post-election survey is based on a representative sample of 2,000 adults living in Northern Ireland who were interviewed face-to-face between May and September 2022. A supplementary online survey of 797 adults conducted between May and June asked people about how they would vote in a referendum on Northern Ireland's constitutional future and to explain, in their own words, the main reasons for their stated intention. The study builds on a survey conducted after the 2016 Northern Ireland Assembly election (held under SN 8293) and complements similar studies of devolved elections in Scotland and Wales.
