Calderdale district has 27 medium layer super output areas (MSOAs). MSOAs are geospatial statistical terms developed by the [Office for National Statistics](https://www.ons.gov.uk/methodology/geography/ukgeographies/censusgeography) (ONS) for the reporting of statistics of similar population sizes.
The ONS has assigned each MSOA with a code (eg E0200224) and a label (eg Calderdale 001).
The [House of Commons Library MSOA names project](https://visual.parliament.uk/msoanames) has given each MSOA a recognisable name that reflects any towns, villages and neighbourhoods in the area represented.
This data set includes demographic profiles for each MSOA in Calderdale using the [LG Inform plus app](https://about.esd.org.uk/about).
