National Survey of Family Growth - (2006-2010) Male Respondent File




The National Survey of Family Growth (NSFG) is designed and administered by the National Center for Health Statistics (NCHS), an agency of the U.S. Department of Health and Human Services, in collaboration with several other federal agencies (see Acknowledgements). The NSFG has been conducted seven times since 1973. The purpose of the survey is to produce national estimates of:

-Factors affecting pregnancy, including sexual activity, contraceptive use, and infertility;
-The medical care associated with contraception, infertility, and childbirth;
-Factors affecting marriage, divorce, cohabitation, and adoption;
-Adoption and caring for nonbiological children
-Father involvement behaviors, and
-Men's and women's attitudes about sex, childbearing, and marriage.

The survey contains key religion variables that may relate to these topics. The survey results are used by the U.S. Department of Health and Human Services and other research and policy organizations to plan health services and health education programs, and to do statistical studies on the topics listed above.

For the 2006-2010 NSFG, statistical design, interviewing, and data processing have been conducted by the University of Michigan's Institute for Social Research (ISR), under a contract with the National Center for Health Statistics (NCHS), in collaboration with the NCHS NSFG team led by William Mosher (Project Officer).

The 2006-2010 NSFG survey represents a shift from periodic surveys to continuous interviewing, with interviews being conducted 48 weeks of every year for four years. This public use data file contains all interviews conducted from June 2006-June 2010. In-person interviews were conducted with 12,279 women 15-44 years of age and 10,403 men 15-44 years of age for a total sample size of 22,682.

The ARDA has added six additional variables to the original data set to enhance the users' experience on our site.

Weight Variable: WGTQ1Q16, FINALWGT30, WGTQ1Q8, WGTQ5Q16, QGTQ9Q16

These 2006-2010 NSFG data are based on a nationally representative sample of the household population aged 15-44. Data users should understand how to account for the design when doing their analyses. The 2006-2010 NSFG design was a significant change in the design of the survey. Please refer to the NSFG 2006-2010 User's Guide for more information.

In the NSFG, Hispanics, blacks, teens, and women were selected at higher rates than others in the 15-44 age group. "Sampling weights" adjust for these different sampling rates, as well as for response rates and coverage rates, so that accurate national estimates can be made from the sample. Because weights vary widely for 206-2010 NSFG respondents, we strongly recommend using the weights in all analyses. Using the weights also will permit replication of the nationally representative estimates that appear in published NCHS reports.

There are five weights provided in the 2006-2010 public use files. The weight WGTQ1Q16 is the main weight to be used in most analyses involving all 16 quarters of data. The four additional weights are provided for analyses of questions that were added at different times in data collection or to compare cases that were collected in the first two years of data collection (quarters one-eight) with cases collected in the last two years of data collection (quarters nine-16).
