The small area model-based income estimates are the official estimates of average (mean) household income at the middle layer super output area (MSOA) level in England and Wales for 2011/12, 2013/14 and 2015/16.
For 2015-16 the figures are average annual income. For 2013/14 and 2011/12 the figures are average weekly income.
They are calculated using a model based method to produce the following four estimates of income using a combination of survey data from the Family Resources Survey, and previously published data from the 2011 Census and a number of administrative data sources. The four different measures of income are:
- Total household income
- Net household income
- Net household income (equivalised) before housing costs
- Net household income (equivalised) after housing costs
Total annual household income is the sum of the gross income of every member of the household plus any income from benefits such as Working Families Tax Credit.
Net annual household income is the sum of the net income of every member of the household. It is calculated using the same components as total income but income is net of:
- income tax payments;
- national insurance contributions;
- domestic rates/council tax;
- contributions to occupational pension schemes;
- all maintenance and child support payments, which are deducted from the income of the person making the payments; and
- parental contribution to students living away from home.
Net annual household income before housing costs (equivalised) is composed of the same elements as net household weekly income but is subject to the OECD’s equivalisation scale.
Net annual household income after housing costs (equivalised) is composed of the same elements of net household weekly income but is subject to the following deductions prior to the OECD’s equivalisation scale being applied:
- rent (gross of housing benefit);
- water rates, community water charges and council water charges;
- mortgage interest payments (net of any tax relief);
- structural insurance premiums (for owner occupiers); and
- ground rent and service charges.
