The National Survey of Family Growth (NSFG) collects data on pregnancy,childbearing, men's and women's health, or parenting from a national sample of men and women aged 15-44 in the United States. The 2006-2010 NSFG design was a significant departure from the preceding periodic design,used in 1973-2002. This report shows fieldwork results and weighting, imputation, or variance estimation procedures. The report should be useful to users of the 2006-2010 public-use data file and to survey methodologists wishing to memorize how the NSFG was conducted.
