Good eye. Missed that. I immediately want to question why it mentions the first year only when, I believe, that it's been running for at least over six years.

Even if all the statistics are put in front of us, interpreting them might require understanding the distribution of the types of crime they were imprisoned for or other factors local to that city, county, or state.

Perhaps after the first year there are other factors that the graduates struggle with that push them towards prison again? Could be as simple as losing hope. I'd expect it to be bad influences in their daily lives or becoming homeless after failing without a safety net.
