There is growing interest in alternative measures of national wellbeing, such as happiness or life satisfaction. This column argues that a small number of survey questions are unlikely to capture all the aspects of wellbeing that matter to people. Using a stated-preference survey, the authors find several aspects of wellbeing to be important that are not commonly included in wellbeing surveys, such as those related to family, values, and security. This approach could be used to provide weights for wellbeing indices.

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.
