Common use of MEPS Panel 1 Weight Clause in Contracts

MEPS Panel 1 Weight. The person level weight for MEPS Panel 1 was developed using the 1996 full year weight for an individual as a “base” weight for survey participants present in 1996. For key, in-scope respondents who joined an RU some time in 1997 after being out-of-scope in 1996, the 1996 family weight associated with the family the person joined served as a “base” weight. The weighting process included an adjustment for nonresponse over Rounds 4 and 5 as well as poststratification to population control figures for December, 1997. These control figures were derived by scaling back the population totals obtained from the March 1998 CPS to reflect the December, 1997 CPS estimated population distribution across age and sex categories as of December, 1997. Variables used in the establishment of person level poststratification control figures included: census region (Northeast, Midwest, South, West); MSA status (MSA, non-MSA); race/ethnicity (Hispanic, black but non- Hispanic, and other); sex, and age. Overall, the weighted population estimate for the civilian, noninstitutionalized population on December 31, 1997 is 267,704,802. Key, responding persons not in-scope on December 31, 1997 but in-scope earlier in the year retained, as their final Panel 1 weight, the weight after the nonresponse adjustment.
