Assignment of Weights. If all key, in-scope members of a family responded to MEPS for their entire period of eligibility for Panel 12, Round 3 or for Panel 13, Round 1 and if the family had a key reference person, then that family received a family-level weight (WGTRU13>0). Reporting units consisting of an individual respondent who was both key and in-scope also received a family-level weight. These single person “family” units can be included or excluded from family-level analyses at the analyst’s discretion. Family-level weights were poststratified to figures obtained from the March 2008 CPS. The family-level poststratification reflects population distributions across family type (reference person married, spouse present; male reference person, no spouse present; female reference person, no spouse present), size of family, age of reference person, location of family (census region and MSA status), and race/ethnicity of the family’s reference person. Table 3-3 shows the number of families with family-level weights for each of the two panels separately, as well as the combined total and the total population estimate represented by the weighted total for all families with family-level weights. Included as families in these counts are individuals living in one person RUs. There are 5,136 such families for Panel 12, Round 3 and 7,821 for Panel 13, Round 1. Thus, in total, there are 12,957 sample families in the file with positive family-level weights (WGTRU13>0). The population estimate of the number of these “family” units (families plus single person “family” units) with family-level weights containing at least one member of the U.S. civilian, non-institutionalized population is 130,610,298 based on summing the family level weights across all 12,957 MEPS families where WGTRU13 is positive. Table 3-3. Families with a family weight for the 2008 Point-in-Time file Panel 12 Panel 13 Combined Population estimate (weighted total of combined sample) Number 5,136 7,821 12,957 130,610,298 It should be noted that CPS and MEPS definitions of family units are slightly different. In particular, CPS does not include xxxxxx children in families or consider unmarried persons who live together as family units. Adjustments were made in the poststratification process to help compensate for some of these differences. Again, note that MEPS population estimates have undergone some “discontinuities” due to an adjustment in the 2003 CPS estimates.
Assignment of Weights. The weight assigned to a logic tree branch should represent the likelihood of that branch being the true model. In most cases, however, weights will be assigned by the experts deriving the input data for the logic tree, based on their judgement of the likelihood of the competing models. Weights can also be derived from e.g. a Bayesian scheme as suggested by

Assignment of Weights. If all key in-scope members of a family responded to MEPS for their entire period of eligibility in 2001 Panel 5 Round 3, or for Panel 6 Round 1, and the family had a key reference person, then that family received a family level weight (WGTRU13>0). Reporting units consisting of an individual respondent who was both key and in-scope also received a family level weight. These individual person units can be included or excluded from family level analyses at the analyst’s discretion. Family level weights were poststratified to figures obtained from the March 2001 CPS. The family level poststratification reflected population distributions across family type (reference person married, spouse present; male reference person, no spouse present; female reference person, no spouse present), size of family, age of reference person, location of family (census region and MSA status), and race/ethnicity of the family’s reference person. The weighted estimate of the number of units (families plus individual person units) with family level weights containing at least one member of the U.S. civilian non-institutionalized population is 118,594,062 based on 13,393 families with WGTRU13>0. It should be noted that CPS and MEPS definitions of family units are slightly different. In particular, CPS does not include xxxxxx children in families or consider unmarried persons who live together as family units. Adjustments were made in the poststratification process to help compensate for some of these differences.
