Science, Technology, Engineering and Math (STEM) majors are among the most sought-after college graduates. They have an easier time finding a job, and they make more money.

Yet at every major college, a higher percentage of men than women major in STEM fields. It's a major reason why men earn more money than women, and many colleges and universities have made graduating more women from STEM majors a priority.

Some colleges are doing better than others.

We investigated which schools have the most female STEM graduates and how much being a STEM major benefits those women financially. To do so, we analyzed data on the 100 American colleges and universities with the most undergraduates.

We found that certain schools, including four of the University of California campuses, graduate far more female STEM majors than the average school. On the other hand, at schools like NYU, barely 1 in 25 women graduate with a STEM major.

The data also shows that the U.S. News and World Report's Top 25 schools vary greatly in their prominence of women in STEM.

Do STEM Graduates Earn More?

Before analyzing the proportion of female STEM majors by school, we wanted to confirm that STEM majors really do make more money than non-STEM majors.

We used 2016 Payscale data to look at median earnings (for both starting salary and mid-career salary) by primary college major. For this analysis, we considered a STEM major to be any degree in Computer Science, Engineering, Biology, Chemistry, Physics, Mathematics, Statistics, or Technology.

Data: Payscale

The results confirm that STEM majors earn higher salaries than their non-STEM counterparts. Straight out of college, STEM graduates earn about 35% more than their non-STEM peers. By mid-career, this gap grows to a difference of 47%.

How much more likely are men to graduate with STEM degrees? The following chart shows the percentage of STEM majors by gender at the top 100 schools from 2013 (the most recent year in the data).

We found that 6.7% of women graduate with STEM degrees compared to 17% of men. This means men are almost 2.5 times more likely to graduate with a STEM degree.

Where Women Study STEM

Which Schools Graduate the Highest Proportion of Female STEM Majors?

1 University of California - San Diego 32.70%
2 North Carolina State University at Raleigh 31.50%
3 University of California - Davis 23.70%
4 University of California - Berkeley 23.50%
5 Virginia Polytechnic Institute 22.20%
6 University of California - Los Angeles 21.70%
7 University of Washington - Seattle 21.60%
8 University of California - Irvine 21.50%
9 University of Michigan - Ann Arbor 20.90%
10 University of Wisconsin - Madison 19.40%
11 University of Illinois at Urbana-Champaign 18.80%
12 Texas A&M University - College Station 18.70%
13 Kent State University at Kent 6.10%
14 Pennsylvania State University 18.60%
15 University of Maryland - College Park 18.50%
16 SUNY Buffalo 17.60%
17 Rutgers University - New Brunswick 17.40%
18 The University of Texas at Austin 17.30%
19 University of Florida 16.80%
20 Michigan State University 16.40%

University of California, San Diego tops the list with one in three women graduating with a STEM degree. UC San Diego's proportion of STEM graduates is three times the national average.

Of the top five schools in the list, three are part of the University of California system. Perhaps the lure of Silicon Valley drives these high rates.

Which Schools Graduate the Lowest Proportion of Female STEM Majors?

We identified the schools at which women were particularly unlikely to choose a STEM major. The following table lists the 20 schools with the lowest proportion of female STEM graduates.

1 Grand Canyon University 1.50%
2 Liberty University 1.50%
3 California State University - Fullerton 3.60%
4 Texas State University 4.20%
5 Utah State University 4.40%
6 New York University 4.60%
7 Ohio University 4.80%
8 California State University - Northridge 5.00%
9 California State University - Fresno 5.30%
10 Central Michigan University 5.50%
11 Middle Tennessee State University 5.60%
12 California State University - Los Angeles 5.70%
13 Kent State University at Kent 6.10%
14 Pennsylvania State University 18.60%
15 California State University - Long Beach 6.10%
16 University of Nevada - Las Vegas 6.20%
17 Grand Valley State University 6.40%
18 California State University - Sacramento 6.60%
19 University of North Texas 6.60%
20 Indiana University - Indianapolis 6.70%

The difference between these schools and those in the top 20 is stark. Only about one in one hundred women at Liberty University or Grand Canyon University choose a STEM major. Both schools are primarily made up of online students.

At New York University, only slightly more than one in 25 undergraduate women choose to major in a STEM subject--one of the lowest rates in the country.

Which Top 25 Universities Graduate the Highest Proportion of Female Stem Majors?

We examined which of the most elite schools were most likely to have female STEM students. The following table shows the proportion of female STEM majors at the top 25 schools according to U.S. News & World Report.

1 California Institute of Technology 98%
2 Massachusetts Institute of Technology 81.30%
3 Johns Hopkins University 55.70%
4 Carnegie Mellon University 43.30%
5 Columbia University 36%
6 Duke University 35.50%
7 Rice University 33.60%
8 University of Pennsylvania 31.30%
9 Princeton University 30.90%
10 Cornell University 30.70%
11 Stanford University 29.10%
12 Emory University 28.90%
13 Harvard University 28.70%
14 University of California - Berkeley 25.70%
15 Brown University 25.60%
16 University of Notre Dame 24.40%
17 University of California - Los Angeles 22.80%
18 Dartmouth College 21.80%
19 Yale University 21%
20 University of Chicago 20.40%
21 Georgetown University 19.30%
22 Washington University in St. Louis 19.10%
23 Vanderbilt University 18.30%
24 University of Southern California 18.20%
25 Northwestern University 17.80%

The top two schools are both engineering schools, although the California Institute of Technology (98%) still has a sizable lead over the Massachusetts Institute of Technology (81.3%). Among non-engineering universities, Johns Hopkins does best at 56%.

Which Top 25 Liberal Arts Colleges Graduate the Highest Proportion of Female Stem Majors?

We also looked at which of the top 25 liberal arts colleges had the the highest proportion of women in STEM. The results are in the below table:

1 Harvey Mudd College 91.40%
2 United State Naval Academy 50.20%
3 Haverford College 32.40%
4 Carleton College 31.80%
5 Pomona College 30.80%
6 Bryn Mawr College 29.10%
7 United State Military Academy 24.30%
8 Swarthmore College 24%
9 Bowdoin College 23.70%
10 Grinnell College 22.60%
11 Hamilton College 22.40%
12 Amherst College 21.70%
13 Bates College 21.70%
14 Wellesley College 21.60%
15 Colorado College 20.80%
16 Colby College 20%
17 Williams College 19.10%
18 Smith College 18.80%
19 Oberlin College 18.50%
20 Middlebury College 18.10%
21 Colgate University 17.80%
22 Wesleyan University 16.30%
23 Macalester College 15.40%
24 Vassar College 15%
25 Washington and Lee University 14.30%

Harvey Mudd, a liberal arts school focusing on math, science and engineering, tops the list. More than nine in ten women who attend the school study a STEM subject. (Its unusual categorization as a liberal arts college is likely because it's part of the Claremont Colleges.)

After Harvey Mudd and the Naval Academy, Haverford tops the list at 32%. The all-women colleges Wellesley and Smith don't score particularly high or low by this measure.

Do Female STEM Majors Repay Their Loans Faster?

We know that the STEM field is majority male, and that STEM graduates make more money than their non-STEM classmates. This led us to wonder if women who graduated from schools with high rates of women in STEM actually had better financial outcomes.

The following chart plots the percentage of women in STEM degrees against the 3-year student loan repayment rate for female graduate of that school. The trendline shows that overall, schools with higher concentrations of women in STEM have female graduates who repay their loans faster.

Repayment2 copy

The data points toward the right of the graph are the University of California schools we saw above. They demonstrate that schools with 20% or more of their female students in STEM graduate women who repay their loans within 3 years nearly 90% of the time.

On the other hand, women who graduate from schools on the left side of the graph, which are schools with fewer than one in 20 women in STEM, have lower repayment rates.

Since women with STEM degrees make more money, it makes sense that they have higher repayment rates.

Choosing a STEM-Focused College


So which college should women interested in STEM attend, and which colleges are graduating women from STEM majors?

To the extent that data can help answer that question, this analysis suggests that there is a lot of variation. Engineering schools obviously graduate many women in STEM, but so do a number of UC colleges, while some large online universities have particularly few women in STEM.

Although the wage gap has slowly fallen, women still make about 78% of what their male peers earn. Since STEM graduates earn hundreds of thousands of dollars more, on average, over their careers, the lack of women in STEM is a major reason why.

Even as Americans consider electing a woman to the presidency, computer science lectures, freshman orientations, and college administrator meetings will remain quiet battlegrounds for gender equality.
