Using Census 2021 data, some changes were made to 2011 OAs as a result of population and household changes since 2011. Additionally, around 200 OA boundaries were selectively realigned to ward boundaries.</p><p>2011 OAs that were still made up of between 40 and 250 households and had a usually resident population between 100 and 625 persons did not change. Otherwise, new 2021 OAs were created by merging or splitting 2011 OAs to make sure they fitted within the population and household thresholds of the unchanged 2011 OAs.</p><p>There are some exceptions where OAs may have more than 625 people, for example, where there is a large prison.</p><p>Outputs from Census 2021 are for 2021 OAs and are made up of unchanged 2011 OAs and new 2021 OAs.</p><h2 class="">Note</h2><p>The map view is limited to 1,000 datapoints and if unfiltered may not show all points.</p><p>Contains both Ordnance Survey and ONS Intellectual Property Rights.</p><h2 class="">TopoJSON Shapefile for Power BI</h2><p>On the <b><i aria-hidden="true" class="fa fa-download"></i> Export</b> tab you will find a file under the <b>Alternative exports</b>.
