Cycle 6 of the National Survey of Family Growth (NSFG) was conducted in 2002 by the National Center for Health Statistics (NCHS), with the participation and funding support of 9 other programs of the US Department of Health and Human Services. This documentation is intended to assist researchers who wish to use the data for statistical research.
Cycle 6 of the NSFG was based on an area probability sample. The sample represents the civilian non-institutional population of the United States, 15-44 years of age. The survey sample is designed to produce national data, not estimates for individual states. The contractor for the survey, the Survey Research Center of the University of Michigan, hired and trained over 200 female interviewers for the NSFG. In-person (not telephone) interviews were completed with 12,571 respondents 15-44 years of age--7,643 females and 4,928 males. The interviews were voluntary and confidential. The response rate was 79% overall--80% for females and 78% for males. The questionnaire for males averaged about 60 minutes in length, while the female interview averaged about 80 minutes.
Further details on how the survey was planned and conducted, reports of the findings from the survey, and contact information to obtain the public use data file, are available at the NSFG web site, at: www.cdc.gov/nchs/nsfg.htm
