Fear of stigmatisation might lead to hiding of behaviours and actions. This column presents evidence that stigma concerns can play a role in health seeking behaviour in the case of mental health. In particular, survey respondents under-report mental health conditions 36% of the time when asked about mental health conditions, and about 20% of the time when asked about prescription drug use. Conditions such as diabetes and cardiovascular diseases are less likely to be under-reported.

How many people are poor worldwide? This column explains that the answer depends on whether one uses survey of national-accounts data to anchor country distributions of income. It then argues that night-time lights suggest that national accounts offer a better estimate. Developing world poverty may be as low as 4.5% in 2010, much lower than the path constructed by surveys.

Whereas the Millennium Development Goal of reducing extreme poverty by half was achieved by 2010, the global hunger rate has only fallen by a third since 1990. Differences in survey design may account for part of this discrepancy. This column presents the results of a recent experiment in which households were randomly assigned to different survey designs. These different designs yield vastly different hunger estimates, ranging from 19% to 68% of the population being hungry.
