Question:
What’s the difference between a polling district, place and station?
Answer:
  1. a polling district is a geographical sub-division of an electoral area, ie a UK Parliamentary constituency, a European Parliamentary electoral region, a ward or an electoral division

  2. a polling place is a geographical area in which a polling station is located. However, as there is no legal definition of what a polling place is the geographical area could be defined as tightly as a particular building or as widely as the entire polling district

  3. a polling station is the actual area where the process of voting takes place.
