Round 1 – Number of RUs eligible for interviewing 11,556 8,710 E. Round 1 – Number of RUs with completed interviews 9,377 7,008 F. Round 2 – Number of RUs eligible for interviewing 9,666 G. Round 2 – Number of RUs with completed interviews 9,222 H. Round 3 – Number of RUs eligible for interviewing 9,380 I. Round 3 – Number of RUs with completed interviews 9,001 Overall response rates through the Spring of 2002 P6: A x (E/D) x (G/F) x (I/H) P7: A x (E/D) Combined: .55 x P6 +.45 x P7 66.8% (Panel 6 through round 3) 72.2% (Panel 7 through round 1) 69.2% When an RU is visited for a round of data collection, changes in RU membership are identified. Such changes include RU members who have moved to another location in the U.S., thus creating a new RU to be interviewed for MEPS, as well as student RUs. Thus, the number of RUs eligible for MEPS interviewing in a given round can only be determined after data collection is fully completed. The ratio of the number of RUs completing the MEPS interview in a given round to the number of RUs characterized as eligible to complete the interview for that round represents the "conditional" response rate for that round. It is "conditional" in that it pertains to the set of RUs characterized as eligible for MEPS for that round, and thus is "conditioned" on prior participation rather than representing the overall response rate through that round. For example, in Table 3.1, for Panel 7, Round 1 the ratio of 7,008 (Row E) to 8,710 (Row D) multiplied by 100 represents the percentage response rate for the round (80.5 percent), conditioned on the set of RUs characterized as eligible for MEPS for that round. Taking the product of the percentage of the NHIS sample eligible for MEPS (row A) with the product of the ratios for a consecutive set of MEPS rounds beginning with round one produces the overall response rate through the last MEPS round specified. The overall response rate for the combined sample of Panel 7, Round 1 and Panel 6, Round 3 has been obtained by taking the sum of the products of the relative sample sizes and the corresponding overall panel response rates. Panel 6, Round 3 represents about 55 perc...

The MEPS Sampling Process and Response Rates. An Overview‌ For most MEPS panels, a sample representing about three-eighths of the NHIS responding households is made available for use in MEPS. This was the case for MEPS Panel 23, Panel 24, and Panel 25. For Panel 26, the sample made available for use in MEPS represented about five- eighths of the NHIS responding households for the reasons discussed in Section 3.1.4. Because the MEPS subsampling has to be done soon after NHIS responding households are identified, a small percentage of the NHIS households initially characterized as NHIS respondents are later classified as nonrespondents for the purposes of NHIS data analysis. This actually serves to increase the overall MEPS response rate slightly since the percentage of NHIS households designated for use in MEPS (all those characterized initially as respondents from the NHIS panels and quarters used by MEPS for a given year) is slightly larger than the final NHIS household-level response rate and some NHIS nonresponding households do participate in MEPS. However, as a result, these NHIS nonrespondents who are MEPS participants have no NHIS data available to link with MEPS data. Once the MEPS sample is selected from among the NHIS households characterized as NHIS respondents, RUs consisting entirely of military personnel are deleted from the sample. Military personnel not living in the same RU as civilians are ineligible for MEPS. After these exclusions, all RUs associated with households selected from among those identified as NHIS responding households are then fielded in the first round of MEPS. Table 3.1 shows in Rows A, B, and C the three informational components just discussed. Row A indicates the percentage of NHIS households eligible for MEPS. Row B indicates the number of NHIS households sampled for MEPS. Row C indicates the number of sampled households actually fielded for MEPS (after dropping the military members discussed above and a small number of NHIS households sampled in error). Note that all response rates discussed here are unweighted. Table 3.1.
