Which small area geographies are used within Active Places Power?

Active Places Power uses small area geographies designed by the Office of National Statistics (ONS) to improve the reporting of small area statistics in England and Wales. They are known as Super Output Areas (SOAs) and were developed as an alternative to Wards for calculating small area statistics. Unlike Wards and Postcode geographies, all SOA represent a similar number of people allowing for comparability across smaller geographic areas. The SOA layers form a hierarchy based on aggregations of Output Areas (OAs), as below:

There are three levels:

• OA | Minimum Population: 100 | Mean Population: 300 | Households: 80 | Constrained by: LSOA | Number of records in England and Wales: ~ 175,000

• Lower SOA | Minimum Population: 1000 | Mean Population: 1500 | Households: 400 | Constrained by: Local Authority Wards | Number of records in England and Wales: 32,482 in England, 1896 in Wales

• Middle SOA | Minimum Population: 5000 | Mean Population: 7200 | Households: 2000 | Constrained by: Local Authority Boundaries | Number of records in England and Wales: 6780 in England, 413 in Wales

The above figure refer to the 2001 output area geographies.  Further information can be found on http://www.ons.gov.uk/ons/guide-method/geography/beginner-s-guide/census/super-output-areas--soas-/index.html
