BOSTON (AP) — There was a slight decline in the number of Black students in Harvard University’s freshman class, the first admitted since a Supreme Court ruling struck down affirmative action in higher education.

The impact of the ruling is still coming into focus at selective universities around the country, with some reporting significant swings in the numbers of students of color and others seeing little change.

In a case sparked by challenges to admissions plans at Harvard and the University of North Carolina at Chapel Hill, the court’s conservative majority last year barred colleges from considering race, leaving many searching for new ways to promote student diversity.

Data released Wednesday by Harvard showed 14% of incoming students identified as Black, a drop of 4% from the class before it. Latino students made up 16% of the freshman class, an increase of 2% while Asian-American numbers remained the same at 37%.

“We have worked very hard for many decades to ensure that students from every background come to Harvard and make a difference to their fellow classmates, the nation, and the world,” William Fitzsimmons, dean of admissions and financial aid, said in a statement. “We will continue to fulfill our mission, even as we continue to follow the law with great care.”

The enrollment changes at Harvard mirror what has been seen at some other colleges, although the declines in the number of Black students have been sharper at some other schools.

Massachusetts Institute of Technology saw the percentage of Black students drop from 15% to 5% while Amherst College saw a decline from 11% to 3%. At Tufts University, the drop in the share of Black students was closer to Harvard’s data, falling from 7.3% to 4.7%.

UNC reported drops in enrollment among Black, Hispanic and Native American students in its incoming class. At Yale, the University of Virginia and Princeton, the change in the number of Black students year-over-year was less than a percentage point.

Many colleges did not share the demographics of applicants, making it impossible to know whether fewer students of color applied, or were admitted but chose not to attend.
