In the NYT, here. Those economists can argue about correlation/causation and the diff-in-diff. But I'll just point out that the NYT doesn't even bother to report the data for HS dropouts. Which would be an astonishing 40% of the students in the Springfield, Oregon school district, just three miles from UO. You can do something to get some of these students into college, by volunteering to help with UO's SAIL program, here.
