The data for this map was downloaded in R, using code based on Alex Singleton's Open Atlas Project script.

The Open Atlas Project provides a book of maps for each local authority area in England and Wales, at a much finer level of geographical detail than the map on this page.

Data: Adapted from data from the Office for National Statistics licensed under the Open Government Licence v.1.0. The data was downloaded from the Key Statistics tables on Nomis. The boundaries are from a generalised (simplified) file from the ONS Open Geography Portal. The map was simplified further to reduce the file size.

The map is rendered using D3 and Leaflet. The code is largely based on tutorials by Mike Bostock and d3noob. The legend is based on a map by Ford Fessenden.

To prepare the data, I used an R script similar to the script for regional maps. The ward polygons were simplified using mapshaper.
