Source

U.S. Census Bureau (2010). Here is the CSV data for all of the United States.

Data manipulation

The only change I made to the dataset was to include a header row in the CSV file; I use csv2json to convert dataset to JSON. I did not attempt to change types. All fields are of type String.

Field descriptions

Field Name	Field Description	Example
state	State Postal Code	FL
statefp	State FIPS Code	12
countyfp	County FIPS Code	011
countyname	County name	Broward County
classfp	FIPS Class Code	H1

FIPS Class Codes

• 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.
