Morten Jerven of Simon Fraser University, author of Poor Numbers, talks with EconTalk host Russ Roberts about the quality of data coming out of Africa on income, growth, and population. Jerven argues that the inconsistency of the numbers and methodology both across countries and within a country across time, makes many empirical studies of African progress meaningless. The conversation closes with a discussion of what might be done to improve data collection in poor countries.
