Sample Design and Response Rates Sample Clauses
The 'Sample Design and Response Rates' clause defines the requirements and standards for how samples are selected and how response rates are measured in a research or survey context. It typically outlines the methodology for choosing participants, such as random sampling or stratified sampling, and sets expectations for acceptable response rates to ensure data reliability. By establishing clear guidelines for both sample selection and response measurement, this clause helps ensure the validity of the research findings and addresses potential biases or inaccuracies in the data collection process.
Sample Design and Response Rates. The MEPS HC is designed to produce estimates at the national and regional levels over time for the civilian, non-institutionalized population of the United States and some subpopulations of interest. The MEPS HC uses an overlapping panel design in which data for two calendar years are obtained through five rounds of data collection. A new sample (new Panel) of households for MEPS is selected each year from among household respondents to the previous year’s National Health Interview Survey (NHIS) conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. (The NHIS is an ongoing general health survey of the U.S. civilian non-institutionalized population.) MEPS Panel 15 spans the two calendar years 2010 and 2011 while MEPS Panel 16 spans 2011 and 2012. This file consists of the subset of data from the fifteenth and sixteenth MEPS panels covering from January 1 through, roughly, the spring of calendar year 2011. More specifically, data from the 2011 portion of the third Round of data collection for the MEPS Panel 15 sample are pooled with data from the first Round of data collection for the MEPS Panel 16 sample (see illustration below).

From 1995 to 2005 the NHIS used the same sample design, and thus the MEPS, which began in 1996, has been based on a single NHIS design through MEPS Panel 11 initiated in 2006. Since, in the NHIS, the same PSUs and second stage sampling units are used each year, the MEPS sample from its inception has likewise been clustered within these same sampling units. However, a new sample design for the NHIS was implemented in 2006. The fundamental structure of the new 2006 NHIS sample design is very similar to the previous 1995-2005 NHIS sample design although the sample PSUs and second stage sampling units for the new NHIS design were selected independent of the sample selection process under the previous design. Of course, there is some overlap between the area populations covered by the sampled PSUs selected under the two designs, mostly the larger ones selected with certainty. As households selected for MEPS participation are selected from among the previous year’s NHIS respondents, the MEPS Panel 12, fielded in 2007, was the first MEPS Panel based on the new NHIS sample design. As a result, the 2007 PIT file consisted of two independent sampl...

This file consists of the subset of data from the seventh and eighth MEPS panels covering from January 1 through, roughly, the spring of calendar year 2003. More specifically, data from the 2003 portion of the third Round of data collection for the MEPS Panel 7 sample are pooled with data from the first Round of data collection for the MEPS Panel 8 sample (see illustration below).

Sample Design and Response Rates. The MEPS is designed to produce estimates at the national and regional level over time for the civilian, noninstitutionalized population of the United States and some subpopulations of interest. The data in this public use set pertain to calendar year 1998. The data were collected in Rounds 1, 2, and 3 for MEPS Panel 3 and Rounds 3, 4, and 5 for MEPS Panel 2. Note that Round 3 for a MEPS panel overlaps two calendar years. The reference period for Round 3 of Panel 2 covers the end of 1997 and the beginning of 1998 while the reference period for Round 3 of MEPS Panel 3 covers the end of 1998 and the beginning of 1999. As discussed earlier, for Panel 3, about 30 percent of the Round 2 RUs had reference periods that extended into 1999, but this will present no problems analytically. All the usual information is presented in the standard variables. The only utilization data that appear on the file are those associated with health care events occurring in calendar year 1998, and all utilization data for 1998 reported by MEPS respondents have been included in this database. The households in this 1998 MEPS database are related to households participating in the National Health Interview Survey in 1996 and 1997. The households (occupied dwelling units) selected for MEPS Panel 2 were a subsample of 1996 NHIS respondents while those in MEPS Panel 3 were a subsample of 1997 NHIS respondents. A household may contain one or more family units, each consisting of one or more individuals. Analysis can be undertaken using either the individual or the family as the unit of analysis. For MEPS Panel 2 several domains of interest were oversampled to provide increased precision for analytic purposes. These domains included households containing persons with one of the following characteristics based on NHIS data: adults with functional impairments, children with limitations in activity, individuals aged 18-64 with expected high medical expenditures, individuals with family incomes expected to be below 200% of the poverty level in 1997, and adults with other impairments. Because some households could be associated with more than one domain, a hierarchical sample selection procedure was employed. If a household could be associated with multiple domains, it was assigned to the domain given the highest priority in the hierarchy.
Sample Design and Response Rates. The MEPS is designed to produce estimates at the national and regional level over time for the civilian non-institutionalized population of the United States and some subpopulations of interest. Data are collected for each MEPS panel to cover a two-year period. MEPS Panel 5 spans the two calendar years 2000 and 2001 while MEPS Panel 6 spans 2001 and 2002. As described previously, this file consists of the subset of data from the fifth and sixth MEPS panels covering approximately the first half of calendar year 2001. More specifically, data from the 2001 portion of the third round of data collection for the MEPS Panel 5 sample are pooled with data from the first round of data collection for the MEPS Panel 6 sample (illustrated below).
