> large, wealthy cities provide more resources for homeless addicts, and so they end up congregating there

There was some bussing of homeless into city centres. But I haven't seen evidence that a majority, let alone significant plurality, of these cities' homeless addicts became homeless somewhere else.

Given that less than half of NYC residents are born in NYC, the null hypothesis would be that the average homeless person is also born outside of the city[1].

(Maybe this demographic skews more towards natives in the case of homeless addicts, but I can’t find a statistic to support that.)

There's several programs for bussing them out:

Although, many cities do this, and everyone leaving is just arriving somewhere else.

For what it's worth, the San Francisco programs supposedly only send them away if they have someone they're going to.

"These three programs all help people relocate outside San Francisco to reunite with family or support networks." (Emphasis mine).
