- Notes for Users:
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 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.

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: Based on the respondent’s state of residence at the time of the interview, a 4-category REGION variable has been created and is available for statistical research purposes. REGION is provided to researchers free of charge, upon request, and can be merged onto the public use data files using the unique CASEID variable. Given the increased risk of deductive disclosure when REGION is merged with the public-use survey data, however, a user agreement must be signed before gaining access to this file.
This data file consists of two variables: CASEID and REGION. There are 10,416 records in this file—5,601 female respondent cases and 4,815 male respondent cases.
REGION  takes these values:
1 = Northeast
2 = Midwest
3 = South
4 = West

If you wish to request the NSFG REGION variable for 2011-2013, please make your request by providing the following materials by email (email@example.com) or regular mail to the address further below:
- a brief summary, on your organization’s letterhead, of the proposed use of the REGION variable. (If you are a student, a faculty advisor should also provide a letter of support for the proposed research.)
- a signed User’s Agreement pdf icon[PDF – 98 KB], which describes the specific protections in place at your institution that meet the NCHS confidentiality standards for data users. Each data user who will have direct access to the REGION variable, including research assistants, must sign an agreement. If emailing the signed user agreements, they must be completely legible, good-quality scans in either PDF or JPG format.
NOTE: When manuscripts are prepared which include analyses including the REGION variable, the requestor must send them to NCHS before being submitted for publication so they can be assessed by NCHS staff for disclosure risk.
When your request is approved, you will be sent an encrypted, password-protected ASCII data file consisting of CASEID in columns 1-5, R_SEX in column 6 and REGION in column 7. Passwords will be forwarded when the requestor confirms receipt of the data file. NCHS makes every effort to process data requests promptly. Once the researcher provides the required materials, requests are typically reviewed within 2 business days, with files sent soon thereafter.
