The G.I. Bill, Standardized Testing, and Socioeconomic Origins of the U.S. Educational Elite Over a Century

We compile, transcribe, and standardize historical records for 2.5 million students at 65 elite (private and public) U.S. colleges. By combining these data with more recent survey and administrative data, we assemble the largest dataset on the socioeconomic backgrounds of students at American colleges spanning the last 100 years. We document the following: First, despite a large increase in the share of lower-income students in the overall college-going population, the representation of these students at elite private or public colleges has remained at similarly low levels throughout the last century. Second, the representation of upper-income students at elite colleges decreased after World War II, but this group has regained its high representation since the 1980s. Third, while there has been no increase in the economic diversity of elite private and public colleges, these colleges have become more racially and geographically diverse. Fourth, two major policy changes in the history of American higher education, namely the G.I. Bill after World War II and the introduction of standardized tests for admissions, had little success in increasing the representation of lower- and middle-income students at elite colleges.
