Codebooks and Documentation
- 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
These documents replace the “Series 1” and “Series 2” reports published by NCHS, which for prior releases can be found within the NSFG’s “Publications and Information Products” pages. This new format presents analogous information, but organized into a summary document with three detailed documents. Hyperlinks within the documents permit navigation within and between them and also access to auxiliary materials and exhibits.

Variance Estimation Examples
Variance estimation examples that can be modified to analyze the 2011–2013 NSFG data are provided on the Cycle 6 (2002) webpage. Those examples are intended to cover many of the common types of variance estimation. Note that the stratum, cluster, and weight variables should be modified to reflect the appropriate 2011–2013 variable names. (See tables below.) See also the 2011–2013 NSFG User’s Guide pdf icon[PDF – 1.16 MB], starting on page 13 for more information on sample weights and variance estimation. If you have any questions about any of these examples, please e-mail the NSFG staff at firstname.lastname@example.org.

Other Data Files
The NSFG ACASI data for 2011-2013 are now included as part of the main NSFG public use files. In addition to the main 2011–2013 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: Unlike in past NSFG file releases, when much of the data collected in the Audio Computer-Assisted Self Interviewing (ACASI) portion of the interview was released separately under a special data user agreement, the ACASI data for 2011-2013 are included in the main public use files for 2011-2013 NSFG that were released in December 2014. Please see Questionnaires, Datasets, and Related Documentation for the 2011-2013 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 2011-2013 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 2011-2013 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 icon[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 2011-2013 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.
