The Key Field
Your output may include a Key field. The Key field is made up of a series of codes, including FIPS codes as well as other codes. This series of codes depends on the geography you chose in Pick Geography. The codes included in the list will mirror the codes of the geographies that you find as you drill down, opening each "+" in Pick Geography. Some examples follow of the value of the Key field; that Key field value parsed into components; and a description of each of the components, with the number of digits for each component code.
