Out-of-pocket payments are the principal source of healthcare finance in most Asian countries, and India is no exception. This fact has important consequences for household living standards. In this paper the author explores significant changes in the 1990s and early 2000s that appear to have occurred as a result of out-of-pocket spending on healthcare in 16 Indian states. Using data from the National Sample Survey on consumption expenditure undertaken in 1993-94 and 2004-05, the author measures catastrophic payments and impoverishment due to out-of-pocket payments for healthcare.
