It's interesting how Cass Park, arguably one of the most impoverished areas in Detroit, is almost totally owned by the Ilitch Family as of 2014; covered mostly by the Cass Park Village and Woodward Square neighborhoods. Even as Little Caesar's Arena neared completion, Cass Park remained one of the poorest parts of Detroit, let alone Greater Downtown.
By 2016, Cass Park had seen little significant change in racial composition or household income, and had worsened its already-extreme concentration of poverty. However, at the same time, it saw a moderate increase in per capita income and a dizzying spike in income inequality (well in excess of the national average of South Africa, the world's most income unequal nation).
It seems reasonable to say that little had fundamentally changed for the better by the end of 2016 in Cass Park, which saw small numbers of the very-wealthy move into an area whose poverty only grew more desperate.
