What About Washington D.C.?

Washington D.C. is neither a state nor a part of another state. Rather, Washington D.C. is considered a district, and it is the capital of the United States. However, the District of Columbia must abide by several federal laws applicable to states, just as other states do. Thus, while Washington D.C. is not a state, it may be treated like one, and it records the smallest total area when compared to any U.S. state.

The total area of the District of Columbia measures only 68 square miles, which translates to 176 square kilometers. In addition, the acreage of Washington D.C. measures 43,520 acres. By comparison, Rhode Island, which is the smallest state, boasts an area nearly 23 times larger than the area of Washington D.C.
