It varies by social group. Most humanities students I knew were interested in dating, whereas most engineering students I knew were more focused on studying and graduating. But anecdotally, every computer science student I knew was in a relationship, and also every math major I knew. The most technically and academically-accomplished people I knew who were the presidents of design teams were also in relationships. This was in a top-30 university in North America.

So, in my personal experience, I found dating to still be big in university. I think this is rational, as I anticipate it to be harder to find a long-term relationship through online dating in one's early-to-mid twenties, versus dating people knwon in-person.

However, for students anxious about economic opportunities (e.g. due to COVID), I do see the appeal to focus on studies and work experience at the expense of dating.
