Congressional District Database for Pennsylvania's new 2018 Congressional Districts

In February 2018 the Pennsylvania Supreme Court ordered the adoption of new congressional district boundaries for the November 2018 congressional election, and for the 116th Congress, for which the newly-elected representatives will take office on January 3, 2019. This database lists more than 2.6 million ZIP+4 codes covering the entire State of Pennsylvania based on the revised district numbers and boundaries.

These ZIP+4 codes, based on the revised districts and boundaries, will be included in our Congressional District Database for the 116th Congress following the swearing-in of the newly-elected representatives on January 3, 2019.


Description
This special Pennsylvania Congressional District Database lists the revised congressional district for each current Pennsylvania ZIP+4 currently defined by the US Postal Service. The ZIP+4 records of this database provide the necessary resolution to find the correct district within a ZIP code which lies in two or more congressional districts. Do you know: more than 140 5-digit ZIP codes in Pennsylvania lie in two or more districts! A single ZIP+4 record normally applies to a single block of a street or sometimes to a single address of a street, which means that this database resolves the district correctly down to the block or address level.

If you have 5-digit ZIP codes but not the ZIP+4s, you can find the correct district more than 90 percent of the time using only the 5-digit ZIP code. Click here for more information.

Please note that this database does NOT contain street address information. This database is useful for finding the district if you already have ZIP+4 data. If you have the street address (but NOT the ZIP+4) then you need to use an address matching product such as our Perfect Address product line to find the congressional district.

File Format
This special Pennsylvania Congressional District Database is available as an ASCII file in CSV format. It lists every active Pennsylvania ZIP+4 as a separate record, and has about three million total records.

Record Layout
Each record contains exactly eight comma-separated text fields, defined as follows:

Field Type Content
ZIP+4 9 digits nnnnn-nnnn
City Name Variable length ASCII 28 alphanumeric maximum
City Place FIPS Fixed length ASCII 5 numeric characters
County Name Variable length ASCII 25 alphanumeric maximum
County FIPS Fixed length ASCII 3 numeric characters
State Code Fixed length ASCII 2 alpha characters
State FIPS Fixed length ASCII 2 numeric characters
Congressional District Fixed length ASCII 2 digits

All fields are treated as text fields, but the fields are NOT quote delimited, to conserve file space. Fields do not contain embedded commas. For numeric fields, leading zeroes are retained in all cases. This prevents problems importing the data into database programs.

In each record, the fields contain data relating to the particular ZIP+4 identified by the ZIP+4 field.

The City name is the city in which the ZIP+4 lies, as defined by the USPS.

The city Place FIPS code comes from the Census Bureau Place FIPS file, which does not always agree with US Postal Service naming and spelling for a given place name. Where no matching city Place FIPS code can be determined, the city FIPS code is set to 00000.

The County FIPS code is a 3-digit numeric field containing a unique numeric code assigned to each county within a state by the US government.

The Congressional District field contains the numeric district number (with leading '0' if less than 10) within the state for that particular ZIP+4. A single ZIP+4 record normally applies to a single block of a street or sometimes to a single address of a street, which means that this database resolves the district correctly down to the block or address level. If a 5-digit ZIP code lies in multiple districts (more than 6000 5-digit ZIP codes lie in multiple districts) the ZIP+4 records provide the necessary resolution to find the correct district within the ZIP code. For states with only a single congressional district, the congressional district field contains 00.

Each record ends in an ASCII CR-LF pair.
