Nationally, men in colleges and universities currently outpace women in earning physics, engineering, and computer science (PECS) degrees by an approximate ratio of 4:1. To better understand the factors driving these gaps, NYU researchers analyzed bachelor's degrees awarded in the US from 2002–2022, and found that the most selective universities by math SAT scores have nearly closed the PECS gender gap, while less selective universities have seen it widen dramatically.
