Employment and Earnings Outcomes for Young Adult Bachelor’s Degree Holders: Findings From the American Community Survey 25th Annual STATS-DC 2012 Data Conference July 12, 2012 Grace Kena William Sonnenberg National Center for Education Statistics
Overview • Background of Analyses • American Community Survey (ACS) and PUMS (Public Use Microdata Sample) Datasets • Uses of ACS PUMS Datasets and Comparisons with Current Population Survey (CPS) Dataset • Selected Employment and Earnings Outcomes Disclaimer: The content of this presentation does not represent the views of the National Center for Education Statistics or of the Institute of Education Sciences.
Background • Indicators on postsecondary outcomes developed as part of Gaps in Access & Persistence Study (GAPS) produced under Congressional mandate and slated for August 2012 release* • educational attainment • labor force participation • median annual earnings, and • employment in STEM occupations *Higher Education Opportunity Act, H.R. 4137, 110th Cong. §1109, 2008
American Community Survey (ACS) • Continuous national survey of the Census Bureau which collects similar data on people and housing as Census 2000 long form. • Sample of housing unit addresses surveyed monthly=> about 3 million addresses each year. • Includes institutionalized and group quarters populations. • Public User Microdata Sample (PUMS) data set: • According to the ACS website, “Microdata are for those users who want to create do-it-yourself tabulations, to be able to further draw on the richness of detail recorded in the ACS.” • PUMS data sets contain about 40% of the full ACS samples. • PUMS data sets are modified to deter individual record identification. • They are available in 1- , 3-, and 5-year varieties. • We used the 1-year PUMS, 2010 data set for GAPS analyses.

ACS – WHY USE IT? • To obtain more reliable estimates for relatively small quantities. • Example: Tabulations for small states (e.g., Alaska) or small racial/ethnic groups (Alaskan Natives) • Example: Median earnings for workforce, by state (by race, age, educational attainment, etc.) • 2010, full-time, full-year workers ages 25 to 34: • ACS 1-year sample=177,364 records; • ACS 3-year sample=545,222 records; • Current Population Survey (CPS) Annual Social and Economic Supplement (ASEC) sample=16,325 records
ACS – WHY USE IT? • To obtain more reliable estimates for relatively small quantities. • Example: State-level analyses for smaller states • Median annual earnings in 2010 for 25 to 34-year-olds in Alaska who worked full-time and throughout a full year • CPS sample size is 193, ACS 1-year sample size is 312, and ACS 3-year sample size is 879 • Yields median earnings of $38,431 (CPS), $43,741 (ACS 1-year), and $39,665 (ACS 3-year) => ALL valid • BUT: less than High School Attainment yields CPS sample of 4 (no valid estimate), ACS 1-year sample of 16 (no valid estimate), ACS 3-year sample of 43 (valid estimate=>$31,101)
ACS – EXAMPLES OF OTHER USES • Example: Analyses by race at the state level • For Colorado: only 6 Blacks in CPS sample; ACS 1-year sample size is 66 • For Mississippi: only 50 Blacks in CPS sample; ACS 1-year sample size is 518 • With regard to Native Hawaiians: 1-year ACS facilitates analyses in 3 States: • Texas with 47 ACS records vs. CPS with 4, • Utah with 59 records using ACS vs. 6 using CPS, and • Washington state with 89 ACS records vs. 7 with CPS • These are ACS 1-year examples. ACS 3-year yields even more records and more valid cell sizes.

ACS – PUMS DATASETS • Sample comparison of median earnings for young adults ages 25 to 34 by state using ACS 1-year, ACS 3-year, and CPS (reference Excel handout) • U.S. total=$49,910 (ACS 1-year), $50,000 (ACS 3-year), $47,990 (CPS) • Estimates seem similar enough BUT cell sizes vary widely • 177,364 records (ACS 1-year), 319,660 records (ACS 3-year), 16,325 records (CPS) SOURCE: 2008-2010 ACS 3-year PUMS Accuracy of the Data
Special Focus: Calculating the Median Income • Elementary statistics: median is the value in the middle • Not the same with Census sample data • Steps in the sample algorithm: • Accumulate the weights of all records with the same income • Sum these accumulated totals until you exceed 50% of the sum of all weights • Interpolate between the associated incomes of prior and current subtotals to arrive at the approximated 50th percentile SOURCE: 2008-2010 ACS 3-year PUMS Accuracy of the Data
