A survey has revealed the wealthiest and poorest areas in the East Midlands.
There are big variations in earning power
The St Matthews area of Leicester was shown to have an average income per household of £13,000, the second lowest in the United Kingdom.
The same area also had the second largest number of households, 40.1%, earning less than £10,000.
The most affluent postcode is the Littleover area of Derby, which has an average income of £43,033, against a national average of £29,374.
Taking into account investments and social security as well as directly earned income, the "Wealth of the Nation" survey, by marketing company CACI, pinpointed wealth and hardship by postcode.
While part of Leicester did badly, it was only area of the city to make it into the national top 10 of low incomes.
The Dunton area of Lutterworth in Leicestershire, was the second highest earning in the region, at £42, 451.
In Nottinghamshire, the highest placed postcode was NG15 in Ravenshead, with an income of £42, 082.
For Lincolnshire it was PE9, Fineshade in Stamford, which averaged at £35,215.
While the figures are estimates, such surveys are used by businesses in their decision about where to put shops and factories and even by local authorities to help inform funding decisions.
