A Note about Sampling Weights

The NLSY79 Child and Young Adult 1994-2016 data set includes revisions to several Young Adult sampling weights as well as the replacement of two revised Child sampling weights.

Young Adult Sampling Weights

Beginning in 2010, young adults over age 30 are only interviewed every four years. The interviewed sample is selected by age as of December 31 of the survey year, so that approximately half of the older young adults are eligible each round. Since 2010, young adults age 31-32, 35-36, 39-40, 43-44, etc. as of December 31 of the target year have not be fielded.

The algorithm creating the round-specific sampling weights did not adequately account for this change in fielding, leading older YAs in the age groups that were fielded (33-34, 37-38, 41-42, etc.) to receive disproportionately high weights. The algorithm has been readjusted and the round-specific sampling weights for the interviewed YAs over age 30 have been replaced in the following variables:

Y26159.00    [YA10WEIGHT]
Y29663.00    [YA12WEIGHT]
Y33318.00    [YA14WEIGHT]

Child Sampling Weights

An error in the code creating the revised round-specific sampling weights that were released in 2002 led to the 1986 and 1988 Child Sampling weights to be incorrectly calculated. The following weights have been replaced for all affected children:

C05812.01    [CSAMWT1986_REV]
C08007.01    [CSAMWT1988_REV]
