Regionally disaggregated estimates of poverty within India's states are typically not computed because of inadequate sample sizes available for geographic or administrative units below the state level. This paper attempts to ameliorate the sample size problem by pooling the 1999-00 NSS 55th round central and state sample data. We use the pooled data to examine regional variation in poverty within Karnataka. The poverty estimates reveal significant geographic imbalances, with much higher levels and concentration of poverty in the northern districts. Regional patterns are found to be reasonably consistent with independent correlates of poverty, including agricultural wages, employment shares, and district domestic products. However, one important inconsistency is that the rural-urban differentials in poverty rates are not credible and warrant further attention.
