Thematic Map

This thematic map shows the system behind the assignment of zip codes, with state names overlaid. Specifically, the creator of this map wanted to demonstrate what would happen if you connected each zip code in ascending order. The pattern illustrates some interesting information relating to the density of zip codes as assigned across the United States. It is important to note that not all of the breaks between zip codes match exactly with state borders, which are imposed behind the zip code distribution lines.
