Very interesting. Would love to see comparisons with LV where sports gambling has always been legal (relative delinquency rates to other states before the ‘18 ruling, especially in the u40 group). Also change in delinquencies in LV as a control (presumably flat)

That feels like it wouldn't provide a useful comparison, because the people who were going to bet on sports when LV was the legal place to do it, would go to LV to do it. Their delinquency rates wouldn't necessarily be reflected in LV, though, since they've come from elsewhere to do it.
