Scores are calculated by area across seven domains: income; employment; health; education, skills and training; barriers to housing and services; crime; living environment. Each small area of the country (called a Lower layer Super Output Area) is given a score in each of these areas, which creates an overall multiple deprivation score.
The data is accompanied by a document providing an explanation of the methodology, a written narrative around the trends for that yet, and explanation of other relevant data sets (https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/6871/1871208.pdf).
