Census 2021 took place during the coronavirus (COVID-19) pandemic, a period of rapid change which will have affected where people worked and studied. For example, it is possible that some people on furlough may have identified as economically inactive, instead of temporarily away from work. To ensure that students were counted fully in Census 2021, a post-collection process to address any overcount/duplication was carried out. Read our Census 2021 student information paper for more information.
