# Estimate - As a HH may contain more than one SHG member, we do not know how many HHs are among the SHG members who did not answer surveys. Estimate = [Counted number of households]+[(No of SHG members not answering a survey)*(1-proportion of households containing more than 1 SHG member among HH survey respondents)]
## Estimate - Number of SHG members is known, but not all SHG members answered a HH survey, so size of all households is not known. Estimate = [(No. of SHG members who did not answer HH survey) × (average HH size at site)] + [No. people in HHs of SHG members who answered HH survey]
