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 2013-2015, and reflect only minor changes and updates.

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 2013–2015 NSFG data. These examples are intended to 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 2013–2015 NSFG User’s Guide[PDF – 893 KB] for more information. If you have any questions about any of these examples, please e-mail the NSFG staff at nsfg@cdc.gov.

Other Data Files
The NSFG ACASI data for 2013–2015 are now included as part of the main NSFG public use files. In addition to the main 2013–2015 public use data files, there are other files available containing Region of Residence and Contextual data. Below are instructions on how to access these other data files, as well as further information about the ACASI data.
ACASI Data: As done for 2011-2013 NSFG, the data collected in the Audio Computer-Assisted Self Interviewing (ACASI) portion of the interview are included in the main public use files for 2013–2015 NSFG, as released in October 2016. Please see Questionnaires, Datasets, and Related Documentation for the 2013–2015 NSFG for all links associated with accessing these data.
If you wish to access ACASI data from 2006–2010 NSFG or prior NSFG surveys, you must still follow the procedures specified for those datasets.
Contextual Data: The 2013-2015 contextual data file consists of six variables: CASEID, the State FIPS code, County FIPS code, Tract code, and Block group code of the respondent’s address at the time of the interview*, and the State FIPS code of the respondent’s address at the time of the previous Census. These data are only available to the research community through the NCHS and Census Research Data Centers (RDCs) due to the increased risk of deductive disclosure of individual respondent’s identities when geographic variables are linked to the survey data. FIPS codes can be used to merge external contextual information with the 2013–2015 NSFG public use files. For more information about using these data, including options on accessing the RDC and associated charges, visit the RDC website. Researchers may also find useful information for working with NSFG data through the RDC in the Community Environment and Women’s Health Outcomes: Contextual Data, [PDF – 5.2 MB].
* ‘Tract’ and ‘Block group’ variables were added after the initial release of this file, bringing the total number of variables from 4 to 6.
Region: Due to a change in NCHS policy, made effective in January 2019, the 4-category REGION variable for 2013-2015 NSFG will no longer be accessible via special data use agreement. The REGION variable for this survey period can only be accessed through the Research Data Center (RDC). For more information about using the RDC, including access and associated charges, visit the RDC website.
