Population is not the same as voters.

Resident population, voting-age population, eligible voters, registered voters and votes cast measure different things. The district population figures here are dated 2020 Census plan references.

Ask four questions.

• Where is the residence?
• Which boundary dates apply?
• How is this office elected?
• Who is serving now?
