One of the biggest challenges in fighting poverty is to know where it is. This column describes a new way to measure poverty by using satellites to count people who live in darkness at night. This shows that the economic benefits of oil booms don’t trickle down to the very poor.

The proportion of the population in the developing world that lives below the poverty line has been decreasing. This column argues, however, that such a counting approach is not the only way to assess whether the poorest have been reached. An alternative is to use the success in raising the consumption floor as an indicator of social progress. When applying such an approach, the author finds little progress for the poorest.
