CDS-2020 time diary weights are provided as “User Generated” Data through OpenICPSR. Due to a low response rate and small sample size for the CDS-2020 time diaries, these weights are considered unofficial and being made available to researchers who understand the limitations (and potential uses) of these data. CDS-2020 was a follow-up data collection in the Fall of 2020 during the Covid-19 pandemic for children who participated in the 2019 wave of CDS. Children’s time diaries in CDS-2020 were collected for a random week day and a random weekend day.

The Recent College Graduates (RCG) survey estimates the potential supply of newly qualified teachers in the United States and explores the immediate post-degree employment and education experiences of individuals obtaining bachelor's or master's degrees from American colleges and universities. The RCG survey, which focuses heavily, but not exclusively, on those graduates qualified to teach at the elementary and secondary levels, is designed to meet the following objectives: (1) to determine how many graduates become eligible or qualified to teach for the first time and how many are employed as teachers in the year following graduation, by teaching field, (2) to examine the relationship between courses taken, student achievement, and occupational outcomes, and (3) to monitor unemployment rates and average salaries of graduates by field of study. The RCG survey collects information on education and employment of all graduates (date of graduation, field of study, whether newly qualified to teach, further enrollment, financial aid, employment status, and teacher employment characteristics) as well as standard demographic characteristics such as earnings, age, marital status, sex, and race/ethnicity. The 1989-1990 survey (called RCG-91 because the data were collected in 1991) contains four data files. Part 1 contains variables from the main questionnaire and includes information on type of degree received, teaching eligibility, certification, salary, and whether the respondent was unemployed. Also included are transcripts for sampled bachelor degree recipients. Part 2 contains verbatim comments from graduates regarding fields of study, occupation, and parents' occupations. Replicate weights are contained in Part 3, and imputation flags are found in Part 4.
