The main idea is that women have been attending college at much higher rates than men since the 1980s, in the U.S. and in other countries around the world. That has led to a big demographic mismatch for people who want to date and marry others of the same educational level. The dating pool for college-educated people in their 30s now has five women for every four men. For people in their 20s, it's four women for every three men.

The gap is even more extreme in certain places. In Manhattan, there are 38 percent more female college grads under the age of 25 than college-grad men, according to Birger's data. The gap is 49 percent in Raleigh, N.C., 86 percent in Miami, 49 percent in Washington and 37 percent in Los Angeles. And it’s not just cities – many rural areas also have these “educated man deficits.”

The last year in the U.S. that more men than women graduated from college was 1981. Since then, the college gender gap has been getting wider every year. In 2012, there were 34 percent more women than men who graduated from college. By 2023, that gap is expected to reach 47 percent.
