Why are young adults, more so 18-20 trying to have babies when they can't even take care of their own duties, such as cleaning up after themselves, job searching if not employed, and saving up for a vehicle if not in possession of one?

There are a myriad of reasons. Not being loved enough as a child and wanting someone to love, as a way of holding onto a significant other, as a means of abusing the social safety net for 18 years, out of spite, because it makes them feel like an adult, the list could go on and on. For a person who can't support even support themselves, none of them are good ones.

Young women get "baby hunger" starting around the age of 12 (or younger). This comes to full flower during the mid to late teens, especially if they aren't busy with college or a demanding job.

Females also mentally and emotionally begin separating from parents and home during their teens.

As for the males, they are at their sexual peak.

Put those three things together and you get babies.

Yes it starts much younger than 18, for some, they think they will "keep" the boyfriend if they give him a baby.

I experienced this because it was normal for my family. In my family a woman has a child at a very early age. Just my personal experience

I experienced this because I was short sighted and didn't make smart choices.

Oh come on -"We're in love and Obamacare will pay for everything". Then we'll get reduced rent rates and go to the food banks for free food. I see this weekly. They come to our church food bank with their tatoos all over, their I phones, "Oh I left my ID home today" and tell us they don't have any money. Oh by the way, "why don't you get some laundry detergent FOR US!" The USA is headed down the wrong way and the gov't is paving the road.
