Quick check in NYC shows that there were 1.7 deaths / 100K for black folks and 1.8 for white folks between 2012 and 2014. Given the urban/suburban breakdown by race, I'd be inclined to limit the geography to not include, say... Wyoming. Comparing NYC is also valuable given the variance in enforcement of jaywalking along racial lines that we explicitly know about thanks to their open data policies.
