2010 FIPS codes for counties and county equivalent entities in the United States, as a data frame. A combination of state and county FIPS codes is a unique identifier for a U.S. county, while a county name is not necessarily.

1	countyFIPS

A data frame with 3235 rows and 5 variables:

state: Two-letter abbrevation for state, such as "TX" for Texas
stateFIPS: Integer FIPS code for state, such as 17 for Illinois
countyFIPS: Integer FIPS code for county, such as 31 for Cook County in Illinois
countyname: Name of county as characters, such as "Cook County". Not necessarily unique.
classfp: FIPS class code; see details.

The FIPS class code is one of five options:

H1: identifies an active county or statistically equivalent entity that does not qualify under subclass C7 or H6.
H4: identifies a legally defined inactive or nonfunctioning county or statistically equivalent entity that does not qualify under subclass H6.
H5: identifies census areas in Alaska, a statistical county equivalent entity.
H6: identifies a county or statistically equivalent entity that is areally coextensive or governmentally consolidated with an incorporated place, part of an incorporated place, or a consolidated city.
C7: identifies an incorporated place that is an independent city; that is, it also serves as a county equivalent because it is not part of any county, and a minor civil division (MCD) equivalent because it is not part of any MCD.
