|---|---|---|---|
| Geographic Boundary | Polygon | 0..1 | The abstract lines or physical features that separate one place or area from another. |
| Census Tract Identifier | Identifier | 1 | Identifies a census tract within a census metropolitan area or census agglomeration. The first 3 digits represent the metropolitan area/census agglomeration code followed by the census tract 'name'. This is then followed by a decimal point and then 2 more digits. These 2 digits represent census tracts that have been split into 2 or more parts due to a population increase. For example, CT 0412.24 means the census tract has been split 24 times. |
| Geography Effective Date | Date | 1 | The first date when the information specified is valid, which is generally the release date of a census. |
