We evaluate the effectiveness of targeting for Brazil's Bolsa Alimentação, a nutrition-oriented cash transfer program conditioned on beneficiary participation in health activities. Geographic targeting of program funds relied on adjusted estimates of municipality child stunting prevalence, or a malnutrition map. This evaluation provides new estimates of municipality child stunting prevalence for Brazil. The improved estimates indicate moderate budgetary misallocation from geographic targeting. However, when geographic targeting errors are combined with those arising from an inconsistency between geographic and household targeting objectives, undercoverage of children at greatest risk of stunting is potentially large.
