The median household income in D.C. might be well above that of the rest of the U.S., and the greater D.C. area might boast some of the wealthiest counties in the country, but the gap between rich and poor in the city is so wide and obvious that it's painful to observe. In late 2012, the Center of Budget and Policy Priorities released a report which revealed that between the late 1990s and mid-2000s, the 16 percent increase in the incomes of the richest 20 percent of D.C.'s population corresponded with a near 19 percent drop in the incomes of the poorest 20 percent. It's a classic case of the rich getting richer as the poor grow poorer.
Furthermore, a 2012 report from the D.C. Fiscal Policy Institute showed that the average income in D.C.'s top fifth was 29 times higher than that of the bottom fifth. Only some are benefiting from the economic growth in D.C., and it's very evident.
