37% of children obviously do not experience a CPS investigation before age 18.
my wife's caseload (adults) "floats around fifty."
My misunderstanding then - what are you speaking to? Even reading this comment, I still don't understand.
> 800 people with my wife's qualifications and caseload is equivalent to 4000/day. there's ~5000 caseworkers in the US
I don't know what the number of children in the system is. as i said in the comment you replied to, here. but the average US CPS worker caseload is 69 cases. which is over 300,000 children per year, because there are ~5000 CPS caseworkers in the US.
I was only speaking to "how do they 'run' that many investigations?" as if it's impossible. I pointed out it's possible with ~1000 caseworkers.
