This study uses Mexico's 2008 National Household Survey of Income and Expenditure to I construct an easy-to-use scorecard that estimates the likelihood that a household has income below a given poverty line. The scorecard uses ten simple indicators that field workers can quickly collect and verify. Poverty scores can be computed on paper in the field in about five to ten minutes. The scorecard's accuracy and precision are reported for a range of poverty lMes. The poverty scorecard is a practical way for local pro-poor programs in Mexico to monitor poverty rates, track changes in poverty rates over time, and target services.
