The people born in the 1990s are now between 25 and 35 years old. Let’s see how they’re doing:

Not so well.
It would be interesting to limit this to Non-Hispanic Whites. The destruction of the Black Family skewed the statistics for the 1970s and 1980s generation. Non-Hispanic Whites mostly managed to get married, with about 92% marrying at some point.
The grey band was an earlier projection. As we can see, it was completely off. It looks like this might finally normalize around 40%, about ten or fifteen years from now. That probably means 50% for Non-Hispanic Whites, which is actually just around my prior predictions.
But, most of this future result is being determined now. In the past, if you were not already in a relationship at Age 30 — actually “single” — a woman had only about a 20% chance of getting married. Many people married around 32 or 33, to people that they became attached to in their late 20s.
Today, with the average time from first “connection” to marriage about five years, we are seeing the results from the pre-Covid era and also pre-RedPill era, when MGTOW (remember that one?) was still a small group. Today, it has become much more mainstream. Also, since 2019 or so, we’ve seen the collapse of dating apps as a functional means of interaction. Actually, they always were, but now nobody expects any success here. Anyway, the curve of marriage over the next five years or so is being set now; and it doesn’t look very good if you ask me.
