Every Michigan county is governed by an elected board of commissioners, and every commissioner is elected from a single district — 619 districts across all 83 counties, on boards of five to 21 seats. The tool finds the district that covers any point in the state, names its county, and shows the population it was drawn on. It does not name your commissioner, and the reason is worth the paragraph below rather than a silent gap.

Why the card shows no name
The State of Michigan's own district layer carries a commissioner's name and party on every one of its 619 polygons, which looks like a free roster. It is not one. The dataset's own description says the values were derived from the canvassed November 2024 election results — so the column is a list of certified election winners, not of the people in office now. That is why it is filled in for every district: a district always has a winner. The fill rate is evidence against maintenance, not for it.
Measured on 3 September 2026: across twelve counties read district by district against their own board pages (123 districts), and about forty more in a second pass, the state's column named the right person 93.5% of the time — and every miss ran the same direction, the layer naming the 2024 winner and the county naming their replacement. One Wayne County district still named a commissioner who had died in June 2025. Four more rows misspell a real surname.
So the names are dropped when the data is built, rather than shipped with a caveat, and the builder refuses to write the file if they ever reach it. The card says so in its own words: your commissioner is not named here, and your county's own board page is the current source. A roster read from each county's board page, refreshed weekly, is a later change and is recorded as an open gap rather than left implied.
What the lookup shows
Select any point in Michigan and the commissioner district card shows the district, the county, and the district's population from the 2020 apportionment it was drawn on. 611 of the 619 districts carry a population figure in the state's data; Baraga's District 1 and the seven Cheboygan districts do not, and the row is simply absent there rather than invented.
The last row on the card is the honest one: Your commissioner — not named here, with one sentence on why. It is there so a reader knows the omission is deliberate and where to look, rather than wondering whether the lookup failed.
Commissioner district, township, city
Michigan layers its local government differently from most states, and three maps that cover the same address answer three different questions.
- Commissioner district — one seat on the county board. Drawn by each county's apportionment commission after the decennial census, under MCL 46.401–46.405.
- Township — an active local government of its own, with an elected supervisor, clerk, treasurer and trustees. Nearly everywhere outside a city, this is who runs local services. The map's Township or City layer names yours, and says whether it is a general-law or a charter township.
- City — independent of any township; a Michigan city is its own local government with no township underneath. Where a city publishes its council or commission districts, the map's City Council District layer carries them.
A village is not a fourth map: every Michigan village sits inside a township and is a separate government on top of it, not instead of it. The map's City or Village card names the village; the township card still applies.
Where the boundaries come from
District boundaries come from the Michigan Department of State, Bureau of Elections — 2021 County Commissioner Districts, the statewide compilation of the plans county apportionment commissions file with the state. All 83 counties are in one service, pre-built and shipped with the app so the lookup works offline and never waits on a server. The layer is named for its 2021 adoption year and labelled 2022 by the state's own viewer for the first election held under it — two names, one layer. The state's record for the dataset says it is a public record with no restrictions on its use, reproduction or distribution. Every source is on the sources & data layers page. The map is free, requires no login, and sets no tracking cookies.
