Household income: model-based estimates

ONS small area estimates of average weekly household income (2011-12)

In October 2015, the Office for National Statistics (ONS) released a set of model-based estimates of average (mean) weekly total household income at a Middle Super Output Area (MSOA) level.  The estimates were compiled using Family Resources Survey (FRS) data together with 2011 Census and administrative data.

A PDF Document briefing note (PDF, 688KB)Opens new window has been prepared which outlines the basis of the estimates and provides maps and figures for all MSOAs in Swansea. 

MSOAs are a statistical geography generated using Census data from groups of LSOAs (Lower Super Output Areas). They have a minimum size of 5,000 people and 3,000 households, with an average population of 7,500. There are 31 MSOAs in the City and County of Swansea.

The estimates indicate a difference of almost £600 between the highest and lowest average MSOA figures for total household weekly income in Swansea, from £883 to £297.

Model-based estimates have been produced for the following income measures:

  • Total household weekly income
  • Net household weekly income
  • Net household weekly income before housing costs (equivalised*)
  • Net household weekly income after housing costs (equivalised).

Further information and the detailed figures are available in the briefing note.


* Equivalised income is where household income values have been adjusted to take into consideration the number and type of people in the household.
