Interesting MIT paper.
50 pages, bullet points and graphs are helpful.

One interesting highlight, getting primarily young black girls out of the inner city
public projects had a lasting positive impact, but the opposite held true black boys.
You can probably toss in some hispanics into the group also.
My theory is that, since 95% of these households are run by women, by teen years'
boys with NO positive male influence start into the cycle of drugs, theft, gangs.....
even in the older suburban ring vs. even in the inner city projects there were
some positive males to influence them. Girls are different.

Moving to Opportunity (MTO) program
that was initiated in the early 1990s. MTO was designed to improve
the well-being of adults and children living in high poverty public
housing by enabling them to move into outlying communities where
poverty rates were substantially lower. One of the most surprising
(and firmly established) set of results from the large body of research
produced by the MTO experiment is that moving families to low-
poverty neighborhoods outside of the central city had starkly different
effects on boys and girls. Girls in treated households obtained better
academic outcomes, engaged in fewer risky behaviors, and reported
better physical health than girls in control households (that is, those
who remained in public housing projects or received standard “Section
8” housing vouchers). By contrast, boys in treated households fared
substantially worse on these same outcomes than did boys in control
households,
