Why It Matters
For millions of American families, the cost of a college degree has grown from a manageable expense into a defining financial challenge. A new academic study tracking tuition data across nearly two centuries reveals that the college affordability crisis is not simply a product of rising tuition — it is the result of tuition growth pulling sharply away from family income, a divergence that began in earnest in the 1980s and has not reversed since.
What Happened
A scholar compiled a database drawing on tuition records from 667 private and public colleges and universities, covering 10-year intervals from 1840 to 2020 and representing 64 percent of institutions established before 1920. The findings, published in the journal History of Universities, trace tuition from its origins through the modern affordability crisis.
For most of the 19th century and into the early 20th, tuition costs were remarkably stable. Annual tuition ranged from $41 to $59 between 1840 and 1910 — equivalent to roughly $1,586 to $2,194 in today’s dollars — and remained essentially flat in inflation-adjusted terms. In 1910, approximately 20 percent of universities charged no tuition at all, including Stanford University, Howard University, and Oregon State University. Only a single college offered tuition-free education in 1840; that number had grown to 119 by 1910.
The competitive push to raise tuition accelerated beginning in the 1920s and 1930s, when college administrators began raising rates faster than their peers. Tuition grew between 150 and 190 percent per decade from the 1920s through the 1950s, and approximately 220 percent per decade through the 1960s and 1970s. Critically, however, family income kept pace through 1980, keeping college tuition at roughly 14 percent of median family income for decades.
The break came in the 1980s. Tuition surged 241 percent over the decade — the highest single-decade growth rate on record — rising from an average of $2,686 to $6,467. Median family income grew only 153 percent over the same period. That gap has never closed. By 2020, college tuition consumed approximately 43 percent of median family income, up from 14 percent before 1980. Most of the cumulative increase since then has been concentrated after the year 2000.
By the Numbers
$44,961 — average private college tuition for the 2025–26 school year. At selective universities, total annual costs including housing, food, and books can exceed $100,000.

More than half of all undergraduate students in 2025 carry student loan debt, up from roughly 25 percent in the mid-1990s.

Zoom Out
The findings arrive amid ongoing federal policy debates over student loan access and repayment structures. A federal judge recently blocked an Education Department rule that would have restricted graduate loan access for nurses and teachers, underscoring the contested terrain around both affordability and loan availability at the national level.
The historical data challenges a common assumption — that tuition increases alone explain the debt burden on American students. The more precise explanation, the research suggests, is the sustained failure of family incomes to keep pace with tuition growth over more than four decades. That structural gap has compounded as enrollment expanded and federal loan availability made borrowing more accessible, increasing aggregate debt even as annual tuition growth rates moderated in the 2010s to 142 percent per decade, the slowest pace since the early 1900s.
What’s Next
The research does not prescribe policy solutions, but its historical framing adds context to ongoing legislative and regulatory debates over higher education funding, loan forgiveness, and institutional pricing. With federal student loan balances approaching $1.8 trillion and the share of students carrying debt continuing to rise, affordability is expected to remain a central issue in federal budget and education policy discussions through the remainder of 2026.
