MEPS Panel 14 Weight. The person-level weight for MEPS Panel 14 was developed using the MEPS Round 1 person- level weight as a “base” weight. For key, in-scope RU members who joined an RU after Round 1, the Round 1 family weight served as a “base” weight. The weighting process included an adjustment for nonresponse over Round 2 and the 2009 portion of Round 3 as well as raking to the same population control figures for December 2009 used for the MEPS Panel 13 weights. The same five variables employed for Panel 13 raking (census region, MSA status, race/ethnicity, sex, and age) were used for Panel 14 raking. Similarly, for Panel 14, key, responding persons not in-scope on December 31, 2009 but in-scope earlier in the year retained, as their final Panel 14 weight, the weight after the nonresponse adjustment. Note that the MEPS Round 1 weights incorporated the following components: the original household probability of selection for the NHIS; ratio-adjustment to NHIS-based national population estimates at the household (occupied dwelling unit) level; adjustment for nonresponse at the dwelling unit level for Round 1; and poststratification to figures at the family and person level obtained from the March CPS data base of the corresponding year (i.e., 2008 for Panel 13 and 2009 for Panel 14).
MEPS Panel 14 Weight. The person-level weight for MEPS Panel 14 was developed using the 2009 full year weight for an individual as a “base” weight for survey participants present in 2009. For key, in-scope members who joined an RU some time in 2010 after being out-of-scope in 2009, the initially assigned person-level weight was the corresponding 2009 family weight. The weighting process included an adjustment for nonresponse over Rounds 4 and 5 as well as raking to population control figures for December 2010. These control figures were derived by scaling back the population totals obtained from the March 2011 CPS to correspond to a national estimate for the civilian noninstitutionalized population provided by the Census Bureau for December 2010. Variables used in the establishment of person-level control figures included: census region (Northeast, Midwest, South, West); MSA status (MSA, non-MSA); race/ethnicity (Hispanic, black but non-Hispanic, Asian but non-Hispanic, and other); sex; and age. The final weight for key, responding persons who were not in-scope on December 31, 2010 but were in-scope earlier in the year was the person weight after the nonresponse adjustment.

These control figures were derived by scaling back the population distribution obtained from the March 2010 CPS to reflect the December 31, 2010 estimated population total (estimated based on Census projections for January 1, 2010). Variables used for person-level raking included: census region (Northeast, Midwest, South, West); MSA status (MSA, non- MSA); race/ethnicity (Hispanic, Black but non-Hispanic, Asian but non-Hispanic, and other); sex; and age. The final weight for key, responding persons who were not in-scope on December 31, 2010 but were in-scope earlier in the year was the person weight after the nonresponse adjustment.
