How do I Find What Subdivision an Address Is In?

Where you are can be answered at a great many levels of detail, from naming your place in the universe ("I'm on Earth") to describing your precise location in a particular room in your house ("on the comfy chair in the dining room"). In between are many geographic divisions and subdivisions, from counties and towns, to school and police and Congressional districts, to local real-estate neighborhoods. The U.S. Census Bureau has a convenient online tool that sums it all up.
Visit the web page of the American Fact Finder at the United States Census Bureau.
In the column on the left side of the page, move your mouse to the link for "Maps" and then click on the link that displays for "Reference Maps: Boundaries."
Enter the zip code of the address you're searching and click "Go." This will open a boundaries reference map for the area of interest.
Click on the link on the left side of the page for "Reposition on a street address or ZIP code." Enter the address of interest and click "Go" to center the map on the address you're searching.
Adjust the map that shows your address. Use the "Zoom" feature at the top of the map to adjust scale.
Click on "Change boundaries and features" on the left side of the page to show the outlines of different geographical divisions and subdivisions.
The Census maps are slow to load but offer a rewarding amount of detail. Be patient!
