The first two digits in the five-digit county FIPS Code represent the state in which the county is located. FIPS codes are assigned in alphabetic order to counties counting by odd numbers. The first county in a state alphabetically is always , the second county is always , the third is and so on. This method leaves a space between each county for insertion of renamed or newly created counties. All while preserving the alphabetic ordering.
The database is too big to include in this article, but we can show you how to download the entire database in a matter of minutes.
If a county FIPS Code shows up in the list as one-digit number you will need to add two zeros to the beginning. If the county code shows up as two-digits, you will need to add one zero.

The decimal is implied and leading and trailing zeros have been preserved. In these files the denominators used to calculate the address ratios are the totals of each type of address in the tract, county or CBSA.
