Data collection began in the 1987-88 academic year with a panel of teenagers (G2) randomly selected from a list of 9th graders attending the St. Paul (Minnesota) Public Schools. G2 respondents have filled out surveys near-annually (exceptions are 1996, 2001, 2006, 2008, and 2010), first administered in their high school classrooms (Waves 1 through 4) and subsequently by mail, through 2011 (Wave 19), when the respondents were 37 and 38 years old. Shorter surveys containing many of the same topics were administered to students in 1992, 1993, and 1994. In 1995, a full survey was administered covering the wide range of topics included in the previous surveys as well as information on career plans and life events that had occurred in the past five years. G2 Waves 9 through 15 (1997-2004) included many of the same questions contained in 1992-1994 surveys. The parents of the G2 cohort (G1) were surveyed in the first and fourth waves of the study, when their G2 children were in the first year of high school and four years later. In 2008, the children of G2 who were age 11 and older were recruited (G3). The first data collection (a mailed survey) from G3 occurred in 2009, followed by the second in 2010, and the third in 2011, again including those children who turned 11, as well as older children who had not joined the study previously. Data collection for the G2 and G3 cohorts for years 2019 and 2020, asks similar questions as previous survey years.本数据集的收集工作始于1987-1988学年，研究对象为从明尼苏达州圣保罗公立学校九年级学生名册中随机抽取的青少年追踪队列G2。G2受访者几乎每年（1996、2001、2006、2008及2010年除外）完成调查问卷：第1至第4波调查在高中课堂内开展，后续均通过邮寄方式进行，直至2011年（第19波），此时受访者年龄已达37至38岁。1992、1993、1994年，研究团队向该群体施测了涵盖多数核心议题的简化版问卷。1995年则开展了全面调查，既覆盖此前各问卷的全部主题，还补充收集了受访者职业规划及过去五年内发生的人生事件相关信息。G2队列的第9至15波调查（1997-2004年）沿用了1992-1994年问卷的多数题目。研究分别在G2子女刚升入高中一年级及四年后，于研究的第1和第4波，对G2队列的父母（G1队列）开展了调查。2008年，研究招募了年龄满11岁及以上的G2子女组成G3队列；G3队列的首次数据收集为2009年的邮寄调查，后续分别于2010年、2011年完成第二、第三次调查，纳入当年年满11岁的群体以及此前未参与研究的年长子女。2019年与2020年针对G2和G3队列开展的数据收集工作，沿用了此前各调查年度的相似问卷题目。
