How were the new households in IHDS II selected?

Selection information: 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.
