There’s little reliable data on local incomes in developing countries, which hampers efforts to tackle the problem.

A team from Stanford University were able to train a computer system to identify impoverished areas from satellite and survey data in five African countries.

“We traditionally collect poverty data through household surveys… we send survey enumerators around to houses and we ask lots of questions about income, consumption – what they’ve bought in the last year – and we use that data to construct our poverty measures.”

However, surveys are costly, infrequent and sometimes impossible to carry out in particular regions of countries because of, for example, armed conflict.

So there is a need for other accurate measures of household consumption and income in the developing world
