I have always been mystified why hetero-women want to change their name to their husband's when they get married. Within lesbian communities this has historically been less of a problem, if for no other reason than historically lesbians couldn't get married.
I had a hetero-friend in grad school (actually had more than one friend in grad school, and most were hetero, but that's another story), who had married right after college, and published her first papers then. She got divorced (ugly) during grad school, and published another few. Then after grad school got married again, and didn't change her name, despite being rather conservative about such things. "Two different names on my CV is sufficient, I don't need a third. No one needs to know my whole marital history".
I know when anyone gets married (or anyone I know, which is indeed, a limited set), it is forever. Margaret Mead thought so, each of the four times she got married. I understand forever. Or the hope of forever. Been there, done that, wore out the t-shirt. I wish everyone to have forever. and ever. It's foolish to talk about statistics, because you and me and our friends are not those numbers. We are, of course, different.
Many of my friends from college/grad school didn't change their names. At least the ones who got married. I had a bunch of friends who didn't get married, and some of those changed their entire names, but that is also a different story. But I noticed that after a while more students I had seemed to be changing their names at marriage. Some of those marriages lasted (and have wonderful children who are getting married, and changing their names). Some didn't. I still believe in forever.
But apropos a discussion on the twits this morning about being called Dr. or Ms. or Mr. or Mrs.:
@arielwaldman Depending on the context, my preference might be Katie or Dr Mack, but it’s NEVER Ms or Miss.

Changing your name, similar to being Mrs. or Ms. or Miss, is a particular problem to women. Everyone has the right to determine what they are called, name and title. But no matter what you do choose, you are making a statement about something.
