Population Estimates Statewide & County Current (Census)
The population and housing unit estimates are released on a flow basis throughout each year. Each new series of data (called vintages) incorporates the latest administrative record data, geographic boundaries, and methodology. Therefore, the entire time series of estimates beginning with the date of the most recent decennial census is revised annually, and estimates from different vintages of data may not be consistent across geography and characteristics detail. <br> <B> When multiple vintages of data are available, the most recent vintage is the preferred data. </B>
The vintage year (e.g., V2021) refers to the final year of the time series. The reference date for all estimates is July 1, unless otherwise specified.
Additional estimates files may also be accessed via the <a href=“https://www.census.gov/data/developers/data-sets/popest-popproj/popest.html”>Census Bureau application programming interface (API)</a>.

Notes:
For vintage 2019: The estimates are based on the 2010 Census and reflect changes to the April 1, 2010 population due to the Count Question Resolution program and geographic program revisions. All geographic boundaries for the 2019 population estimates are as of January 1, 2019.
For vintage 2021: The estimates are developed from a base that incorporates the 2020 Census, Vintage 2020 estimates, and 2020 Demographic Analysis estimates. The estimates are developed from a base that incorporates the 2020 Census, Vintage 2020 estimates, and 2020 Demographic Analysis estimates.

Columns
| Name | Socrata field name | Column name in sgr mount | Data type | Description |
|---|---|---|---|---|
| Date Description | date_description | date_description | Text | Provides the as of date and type of population estimate. |
| County Name | county_name | county_name | Text | This is the name of the Pennsylvania County. Pennsylvania has 67 counties or Pennsylvania for Statewide information. |
| Vintage Year | vintage | vintage | Number | The vintage year (e.g., 2021) refers to the final year of the time series for the reference year (as of date) of the population estimate. |
| Georeferenced Latitude & Longitude | georeferenced_latitude | georeferenced_latitude | Point | A generic georeferenced Latitude & Longitude point within the county. These points can be used to create visualizations such as maps to show the data by county. A point is also provided for outside of the state (on a map it will sit to the southeast of the state). This number represents the total number for the state and this location provides a spot on a map to display the PA number without having it duplicate within a county when using in a mapping visual. |
| County FIPS | county_fips | county_fips | Text | The FIPS county code is a five-digit Federal Information Processing Standard (FIPS) code (FIPS 6-4) which uniquely identifies counties and county equivalents in the United States, certain U.S. possessions, and certain freely associated states. This is the 3-digit part of the 5-digit county FIPS code specifically standing for the county. |
| As of Date | as_of_date | as_of_date | Calendar date | Provides the "As of" date of the population estimate. |
| Population Description | population_description | population_description | Text | Describes the year, type, as of date, and vintage of the population estimate. |
| State FIPS | state_fips | state_fips | Text | These are the first 2 digits of the 5-digit Federal Information Processing Standard (FIPS) code that designate the State association. Each State has its own 2-digit number and each County within the state has its own 3-digit number which are combined into a 5-digit number to uniquely identify every US county. For more technical details : Federal Information Processing Standards Publications (FIPS PUBS) are issued by the National Institute of Standards and Technology (NIST) after approval by the Secretary of Commerce pursuant to Section 111 (d) of the Federal Property and Administrative Services Act of 1949 as amended by the Computer Security Act of 1987, Public Law 100-235. Federal Information Processing Standard (FIPS) 6-4, Counties and Equivalent Entities of the U.S., Its Possessions, and Associated Areas -- 90 Aug 31 , provides the names and codes that represent the counties and other entities treated as equivalent legal and/or statistical subdivisions of the 50 States, the District of Columbia, and the possessions and freely associated areas of the United States. Counties are considered to be the "first-order subdivisions" of each State and statistically equivalent entity, regardless of their local designations (county, parish, borough, etc.).
