I'm going to be doing a presentation for my local philosophy club on why men are walking away from marriage and having children. While I have most of the research and sources I want to use for it there's a few things I've read in the past I can no longer find sources for. I wanted to open up and ask if anyone had sources to a few things since I can't seem to find things I remember reading in the past.

1) I remember there was a twitter poll asking women if they prefer to date feminist men and it overall said they prefer not to.

2) I remember reading some article that said if you look at the effectiveness of birth control vs the number of women who say they're on birth control vs the amount of children born from unplanned pregnancy. It's something like 1/3 of women lie about being on birth control.

Those were the two main things I couldn't find. If anyone else had any unusual evidence I should consider for the presentation feel free to link sources. (I already have quite a bit of stuff on divorce rates, alimony, child support, ect) Thank you for your time.
