Household income quartiles

census-message-logo

This topic has been updated with 2016 Census data for all areas. What's this?

In the National Growth Areas Alliance (NGAA), the 'medium highest' quartile was the largest group in 2016, comprising 28% of households with income.

Households form the common 'economic unit' in our society. Household Income is one of the most important indicators of socio-economic status. With other data sources, such as Qualifications and Occupation, it helps to reveal the National Growth Areas Alliance (NGAA)'s socio-economic status and economic opportunities. Household income levels are not comparable over time because of the influences of economic change such as wage level fluctuations and inflation. The income quartile method is a powerful and objective way of looking at income data and in particular, how it is changing.

A detailed explanation of how Household Income quartiles are calculated and interpreted is available in specific data notes.

Derived from the Census question:

'What is the total of all wages/salaries, government benefits, pensions, allowances and other income the person usually receives?'
