Coefficients of variation of measurement errors of Education, Life Expectancy, and Gross Domestic Product, over HDI

NOTES: Coefficients of variation (CV) for an index for country i: σi/μi, where σ is the standard error of the country‐specific measurement error, and μ is the country‐specific mean. Countries are ordered according to their Human Development Index (HDI). Measurement errors are from Wolff, Chong, and Auffhammer (2011). The graph shows that measurement errors generally decrease for countries with higher HDI, and that life expectancy is associated with lower measurement errors, especially for high HDI countries.
