Do you hold data on the average household income within each parish on the Island?

I would like the map of Multiple Deprivation Index for the whole of Jersey please together with accompanying data. This extends to the Multiple Deprivation Index for each parish and also each ward within St. Helier.


Statistics Jersey hold information from the 2014 / 15 Household Income survey and have been able to analyse the data by parish, to give average (mean) household income by parish.

It should be noted that the data source is a random sample survey of around 1,000 households across Jersey: therefore for particular parishes, the average is based on a small number of households and conclusions should be drawn with care.

The count of households contributing to each parish average is given (rounded to the nearest 5) to guide the interpretation of the average household income (which has been rounded to the nearest £100). Household income has been provided as net income before housing costs, and net income after housing costs. It has been provided in unequivalised form – that is the actual household amount, which will vary according to the size and makeup of the household. For example households in St. Helier on average have smaller household size than those outside of St. Helier. For more information on the components included in these definitions of household income, see report at the following link:

The “Index of Multiple Deprivation” is a UK specific study which does not extend to Jersey. Statistics Jersey would be happy to discuss whether any other datasets that they hold would be helpful. For example, the visual census report provides information at vingtaine level.
