Comparing Earnings Outcome Differences Between All Graduates and Title IV Graduates

Recently, two public data products have been released that publish earnings outcomes for college graduates by program of study and institution: Post-Secondary Employment Outcomes and College Scorecard, from the Census Bureau and U.S. Department of Education, respectively. While the earnings data underlying the data products is similar, persons eligible for the frames of the two products is different, with College Scorecard restricted to only students that receive Title IV aid. This paper documents how these differences in the population studied affect the published earnings outcomes. I show that at an institution, of the institutions in my sample, an average of sixty percent of baccalaureate graduates receive Title IV aid, and that the lower the coverage, the large the difference in earnings measurement. Additionally, I show that short-run earnings outcomes are very similar for these two samples, while longer-run outcomes (10 years after graduation) are significantly lower for the Title IV population. I also show that program ranking can change significantly when considering the Title IV population rather than the entire graduate population.
