This table shows the number of households and income class distributions for each group. Our income class categories are defined as "poor" (income below 175% of the poverty line for a family of four, "affluent" (income more than 350% of the poverty line,), and "middle income" (those falling in between). For “poor” we used values of under $22,500 in 1990, $30,000 in 2000, and $40,000 in 2005-2009. For “affluent” we used values of over $45,000 in 1990, $60,000 in 2000, and $75,000 in 2005-2009.
The first section of the table (Total Households) shows the overall household distribution by group. Subsequent cells in each column provide both the count and percent for the number of households within each income class.
