Bill maher in his most recent episode referred to data showing that about 60% on men under 30 identify as single while only about 30% of women under 30 do. He said “I didn’t know that there’s so many lesbians” but jokes aside it has got to be something else.
I believe that it’s mostly because men over 30 (not captured by the data) are dating women under 30. Nothing unhealthy about that really and gives us all hope

Also maybe because small segment of “alpha” males date multiple women and all women who “know their worth” compete for those same men. That does seem a bit unhealthy. But like Louis ck said: if you feel bad for unfuckable people you can go ahead and fuck them.
