1988 IFSS_WEIGHT adjustmentIn the 1988 NSFG, the weight variable is scaled differently than in other years. To estimate population counts or make comparisons using other surveys, the variable IFSS_WEIGHT needs to be divided by 100 in the 1988 NSFG. The weight variable will be modified in future releases of the data. In the current version of the data the weight can be adjusted using the following code:
In SAS: IFS IFSS_SOURCE=1988 THEN IFSS_WEIGHT=IFSS_WEIGHT/100;
In Stata: replace IFSS_WEIGHT=IFSS_WEIGHT/100 if IFSS_SOURCE==1988
