Final sample of Individuals

Individuals interviewed in both rounds -- 150,995
Individuals interviewed only in IHDS-II -- 53,582
Individuals interviewed only in IHDS-I -- 64,753

Reminder: The term "individuals interviewed" is a euphemism. Much of the information about individuals is collected through interview with adult male and female respondents in the household.

Selection information for new households in IHDS-II: In urban blocks and rural areas of northeastern states where 5 or more IHDS households were lost to attrition, the interviewers were asked to notify NCAER monitors of this loss. Once the loss was verified via physical check, a replacement household was randomly selected in the same neighborhood to refresh the sample. This has led to 2134 new households being included in the IHDS-II sample.
