In fall 2021, of 15.4 million US undergraduates, women made up 58 percent of total undergraduate enrollment — 8.9 million women against 6.5 million men (42 percent). ^[1]

What it does and doesn't establish

The enrollment figure is among the most solid in this database: federal data shows women as a clear undergraduate majority, and male enrollment fell faster than female enrollment over the 2010s. What the number does not establish is any cause — it documents a gap, not a rigged system, and it says nothing about dating markets or hypergamy. Full context: Do women now outnumber men in college?
