The NLSY97 consists of a nationally representative sample of approximately 9,000 youths who were 12 to 16 years old as of December 31, 1996. Round 1 of the survey took place in 1997. In that round, both the eligible youth and one of that youth's parents received hour-long personal interviews. In addition, during the screening process, an extensive two-part questionnaire was administered that listed and gathered demographic information on members of the youth's household and on his or her immediate family members living elsewhere. Youths are interviewed on an annual basis.
Data from rounds 1 - 7 of the NLSY97 were released in June 2005. The event history file and the confidential geocode data file for rounds 1-7 will be released in October 2005.
