The Final Weight for 2013. The final raking of those in-scope at the end of the year has been described above. In addition, the composite weights of two groups of persons who were out-of-scope on December 31, 2013 were poststratified. Specifically, the weights of those who were in-scope some time during the year, out-of-scope on December 31, and entered a nursing home during the year were poststratified to a corresponding control total obtained from the 1996 MEPS Nursing Home Component. Those who died while in-scope during 2013 were poststratified to corresponding estimates derived using data obtained from the Medicare Current Beneficiary Survey (MCBS) and Vital Statistics information provided by the National Center for Health Statistics (NCHS). Separate decedent control totals were developed for the “65 and older” and “under 65” civilian noninstitutionalized populations. In developing the final person-level weight for 2013 (PERWT13F), an additional raking dimension was included to adjust the proportion of persons under age 65 with at least one inpatient discharge based on independent sources of data reviewed by AHRQ. The table below shows ratios of weighted numbers of non-elderly persons that resulted from including this additional raking dimension to that of corresponding estimates without the additional dimension. Ratio of Adjusted to Unadjusted Weights Number of Inpatient Discharges (IPDIS13) Non-elderly (AGE13X < 65) 0 0.98938 1+ 1.21587 Overall, the weighted population estimate for the civilian noninstitutionalized population for December 31, 2013 is 312,098,312 (PERWT13F>0 and INSC1231=1). The sum of person-level weights across all persons assigned a positive person-level weight is 315,721,982.
