What are different weight variables?
WT — Sample weight for the household, most useful and usually used in almost all analyses
FWT — Integer weight (truncated from WT) for STATA routines that require integer weight
INDWT — WT * NPERSONS — this represents number of individuals in the household for analyses that require individual specific weights (e.g. Head Count Ratio for Poverty) when using the household-level file
INDFWT - integer value of INDWT.
