At least in Russia, I observed an opposite with women. All women of my generation I knew who were into thing like engineering did settle down in early twenties.

Russia is a tought life country. A decision to start a family when you are still in your prime may make more sense there.

Engineering is mostly male, so it's easier for female engineers to find spouses from among their classmates/coworkers (and harder for male engineers).
