STATES
US State Information

STATES is a dataset directory which contains some information about American states.

Files are available listing the area, population, capitals, postal codes, statehood date, and other information. In most cases, the files include information for all 50 states, but also the District of Columbia, Puerto Rico, and the United States itself.

In most cases, the files contain a single line of data for each state. The lines are given in alphabetical order of the full state name. Each line begins with a two-letter postal code identifier for the state, whose alphabetic order is "almost" consistent with that of the full state names.
