Codebooks and Documentation

• Codebooks:Webdoc, the NSFG’s interactive online codebook, was deactivated as of 12/31/20. Public-use file indexes (Appendix 1a, 1b, and 1c linked below) can be searched to find variable names or identify relevant variables based on key words in variable labels. The section letters noted in the file indexes correspond to the sections of the codebook, so the file indexes indicate which codebook PDF will contain your variables of interest.

Design and Data Collection Methods

Beginning with the release of data for 2011–2013, detailed information on the survey design and operations, weighting, and variance estimation was compiled in four documents available on the NSFG website. These documents replace the “Series 1” and “Series 2” reports published by NCHS for the 2006–2010 and earlier releases, which can be found within the NSFG’s “Publications and Information Products” pages. The survey design and all related aspects were planned with the entire period 2011 to 2019 in mind, thus are consistent from release to release. The documents below provide information on survey design and operations for  2015-2017, and reflect only minor changes and updates.

• 2015-2017 National Survey of Family Growth (NSFG): Summary of Design and Data Collection Methods [PDF – 432 KB]
• 2015-2017 National Survey of Family Growth (NSFG): Sample Design Documentation [PDF – 552 KB]
• 2015-2017 National Survey of Family Growth (NSFG): Sample Error Estimation Design [PDF – 118 KB]
• 2015-2017 National Survey of Family Growth (NSFG): Weighting Design Documentation [PDF – 527 KB]

Variance Estimation Examples

Each of the PDF files below provides programs and output in SAS and STATA for three examples of variance estimation for the 2015–2017 NSFG data. These examples cover some of the basic types of variance estimation you may do in your analyses. See also the section “Sample Weights and Variance Estimation” in the 2015–2017 NSFG User’s Guide [PDF – 982 KB] for more information. If you have any questions about any of these examples, please e-mail the NSFG staff at nsfg@cdc.gov.

Variance Estimation:

• Example 1. Percentage of Women Ages 15–49 Currently Using the Oral Contraceptive Pill, by Age
• Example 2. Mean Number of Children Ever Born, by Place of Residence for Women 20-49 Years of Age
• Example 3. Percentage of Men 20–49 Years of Age Who Have Ever Had One or More Biological Children, by Hispanic Origin and Race [PDF – 94 KB]
