Students in the specialized high schools came from census tracts where the median household income averaged $62,457 compared with $46,392 for students in other high schools. (All dollar amounts are reported in 2012 dollars).

If we rank the census tracts by their median income and then divide the tracts into equal fifths (quintiles), we observe large differences between the share of students in specialized high schools and other high schools from each quintile.
