The University of Massachusetts study looked at all six New England states together and individually and relied on a detailed analysis of patterns shown in US census data to draw its conclusions. This methodology contrasted sharply with OSPRI's scientific method which was to survey the friends of RISC founder Harry Staley and Hasbro honcho Alan Hassenfeld.

The census numbers show that when unemployment goes up, population declines drastically as more people leave Rhode Island and a lot fewer people move to the state.
Oddly, the study data shows that when taxes go up, fewer people leave the state and a lot fewer people move here. The numbers smash OSPRI's theory about tax increases.
The statistics show affordable housing to have a positive effect (depending on how you define "positive") on population by causing fewer people to leave and more people to move here. In our Charlestown bizarro world, of course, we view population loss as a good thing.

I'll close with these facts for you to chew on. First, most people never move out of state for any reason. Only 3% of the population moves to another state in any given year and 57% have never lived in another state. According to IRS tax return statistics, Florida was not the top choice of Rhode Islanders moving out - Massachusetts was the top pick by a margin of two and a half to one over Florida . And for every two Rhode Islanders who take up residence in Florida, one Floridian decides to chuck the bugs, hurricanes and sweat to move to Rhode Island. Go figure that out, OSPRI.
