ADMINISTRATIVE DIVISIONS OF UNITED STATES

   At the administrative level United States are a federation made up of 50 states and the District of Columbia with the capital Washington; Alaska, with over 1.7 million square kilometers, is by far the state with the largest extension, followed by Texas, California and Montana, while speaking of population we have California in first place, with Texas in second place, with respectively over 39 million and 29 million people and also Florida and New York over 20 million inhabitants.

   The two largest cities in the United States are New York and Los Angeles, with the first on the Atlantic Ocean and the second on the west coast on the Pacific Ocean, spaced nearly 4,000 kilometers apart! In all, there are 10 cities with at least 1 million inhabitants, but they are almost always at the center of a much larger urban agglomeration; as can be seen from the second map, some areas of the country are more densely populated, while others, especially the north-west, are totally devoid of large urban centers.
