^*L: Low, LM: Lower middle, UM: Upper middle; Classifications are for the survey year.

^**Population size is from the United Nations World Population Prospects, 2019 revision, data for the nearest year to the survey year.

^***Sample size after excluding individuals with missing data.

^****These estimates are unweighted.

^†This is an approximate estimate of the share missing as we were not able to exactly determine which individuals in the survey were eligible for the blood pressure measurements.

^‡The Indian data were collected as two separate surveys; this response rate is for the District Level Household Survey 4, which covered the majority of the Indian states. The second survey, the Annual Health Survey, did not publish a response rate.
