New Data Available through the RDC

National Health Interview Survey (NHIS)

• Preliminary Quarterly Microdata Files

A preliminary microdata file for the January–June 2014 National Health Interview Survey is now available through the NCHS RDC. NHIS data users can analyze this file without having to wait for the final annual NHIS microdata files to be released.

National Survey of Family Growth (NSFG)

• National Survey of Family Growth 2011-2013 Release  

The National Survey of Family Growth has released 2011-2013 public use data files. Restricted data has been made available through the Research Data Center.

• The Interviewer Observations File 

This a special data file that contains responses from the NSFG interviewers about the respondent and the interview setting. This file will not be provided for the NSFG 2011-2013 interview data released in December 2014, but will be compiled once four years of interviews have been collected, covering 2011-2015. The Interviewer Observation data are only available for use in the Research Data Center. 

• Contextual Data

The 2011-2013 contextual data file consists of three variables: CASEID, the State FIPS code, and the County FIPS code of the respondent’s address at the time of the interview.  These data are only available through the Research Data Centers 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.
