as lottery games using both Suits Indices of Progressivity and regression a
nalysis. Per capita purchases of the individual games were regressed agains
t variables measuring income, black and Hispanic populations, education lev
els, gender, age, and the purchases of other lottery products. The results

t game, should be classified as an inferior good. Furthermore, differences
