This is not a single-district place. Legislative boundaries are drawn from precincts, not postal or municipal ones, so they cut across both. The table below gives each district and the share of registered voters in it — the largest share is not the whole answer, and if you need your own district you need your address rather than your ZIP.

What this page will not compute

Each of these is a number a reader might reasonably expect. None of them follow from the records we hold, so we do not publish them.

Your own district
This place is split, and the split is by precinct rather than by street. Nothing on this page can tell an individual which district they are in — only an address lookup at the Secretary of State can, and this page is not a substitute for it.
Where the city boundary runs
City limits change by annexation, and the precinct file follows the county assessor rather than the city. A recently annexed street may still be counted with its old precinct.
Anyone not registered to vote
Every share on this page is a share of registered voters. Residents who are not registered are not counted, so this is not a population figure and should not be read as one.

Every figure above is read from a primary source and rebuilt on a schedule. Nothing here is modelled or inferred; where a source is silent the page says so rather than filling the gap.
