Vist Census.gov and search the U.S. Census Bureau's State and County Quickfacts index by city, town or ZIP code to obtain county information. Counties are commonly named after people, geographic features, other places, Native American tribes, and animals.
In general, Southern and Midwestern states have the most counties. Virginia first introduced the county as a governmental administrative unit while it was still a colony. All states recognize the unit, except Louisiana and Alaska, where the term "county" is replaced by "parish" and "borough," respectively. Texas has the most counties of any state with 254, while Delaware recognizes only three. Rhode Island and Hawaii tie for second lowest number of counties with five each. Colorado introduced the newest county in 2001, while in the U.S. territories, districts or municipalities are used.
