Looking for an affordable apartment without compromising my and my daughter's safety?

Why are decent (emphasis on DECENT) apartments so ridiculously priced? I can't see myself being able to afford rent any more than $1100/month but even that isnt enough to get me an okay apartment in a non-compromising area. I currently live near the border of Chino and Ontario Ca. It's a decent area. No real crime but there are just one too many people under one roof, tension is rising, and my mother is very abusive. I have to leave but every apartment near there is either WAY too compromising. (my fancy word for "ghetto") or WAY too high end. There is no in-between. All I'm asking is for an apartment that is safe enough where my car won't get broken into once a month and I don't have to hear crack heads talking to themselves outside my window. I don't see why that has to cost more than $1100. My options are kind of small. I can't really consider a roommate because in light of my daughter living with us there would be restrictions that I doubt any independent person would wanna deal with. (i.e. random visitors, loud music/tv, cursing, etc..) and I can't do studios. The space is just way too small for me and my daughter and really, mostly compromising areas are the only ones to offer studios anyway. I'm just looking for a decent 1 bedroom apt. in a decent area. Any suggestions would be appreciated. Thank you.
