U. S. Government/political divisions
Nearly every place on earth where people live and work is covered by a complicated mesh of political divisions or jurisdictions. For example, a typical registered voter in the US will live in a particular voting district or precinct in a ward in a county in a state, though the number and names of the specific political divisions in this hierarchy may differ between locations. A specific voting district will generally be part of a school and a water district plus legislative districts for the United States House of Representatives and the state legislature. In states with bicameral legislatures, that voting district will be part of both a state house of representatives and a state senate district. People further live in either a municipality or an unincorporated area. Some will live where the city and county governments are combined, as in Denver, Colorado, and San Francisco, California.
Suppose you want to petition your government for something, or you want to organize to petition your government for a redress of grievances. How can you to identify the correct political division responsible for the issue that concerns you at that moment?
Many registered voters can check their local electoral agency for this. For example, a registered voter in Johnson County, Kansas can go to jocoelection.org, the web site of the Johnson County, KS, Election Office, click "Voter information", then "Voter lookup", enter "First Name", "Last Name", and "DOB (mm/dd/yyyy)", then click "Look me up". When I have done that, it told me which district I was in for the US House of Representatives, Kansas House and Senate, and similar district information for county, municipality, school boards and water district.
But how can I find this information for a particular set of geographic coordinates if I'm not a registered voter there?
