Constituency data: Social Mobility Index by Constituency (SMIC)

This page provides the Social Mobility Index by Constituency (SMIC) data. The SMIC provides local level estimates for Westminster Parliamentary constituencies in England. It is based on the indicators and methodology used in the social mobility index by local authority published by the Social Mobility Commission.

The House of Commons Library’s SMIC provides constituency level comparisons and rankings of 14 variables representing four life stages from early years to adulthood. This index addresses the question:

How do the chances of disadvantaged children doing well later in life vary between constituencies?”

Information about SMIC variables, methodology and data sources is available in the House of Commons Library briefing paper – Social Mobility Index by Constituency, England.

Notes and sources

Information about SMIC variables, methodology and data sources is available in the House of Commons Library briefing paper Social Mobility Index by Constituency, England.

The first part of this Briefing Paper provides background information about the SMIC (Section 1); analysis and maps of the overall SMIC rankings (Section 2) including the interactive SMIC dashboard (Section 3) which is available to download for each constituency in England; shows how the SMIC rankings differ in each of the four life stages, from Early years through to Adulthood (Section 4), between and within each English region (Section 5) and with regards to large cities or small towns based on the ‘city/town classification’ of constituencies published by the HC Library (Section 6).

The SMIC rankings for each of the 533 constituencies in England (overall, within each region and for each of the four life stages) are given in Appendix 1. Appendix 2 provides technical details about how we constructed the SMIC, its methodology and variables, including: information about each variable; the data coverage and limitations; and how outliers, which can skew an analysis, are dealt with.
