Then followed by two biggest groups with the lowest income under $25,000 and between $25,000 to $49,999. They both contained 25 millions to 28 millions respectively. After That, the small number of households came from the middle range income of either $50,000 to $74,999 and $75,000 to $99,999, which accounted for more than 20 millions and less than 15 millions individually.
