Schoolcraft County, Michigan Map with Townships and Land Area

How to use this map

The map opens on the Divisions view with all 9 of Schoolcraft County’s municipalities drawn straight from Census boundary files. Click any one to pin it and read its figures: land area in square kilometres, 2020 population and the density that falls out of those two. The tabs above the map change what the shading means. Divisions gives each unit its own colour so you can tell neighbours apart at a glance. Land area shades by size. Satellite drops one metre aerial imagery under the boundaries. Blank outline strips the fill away for printing or tracing.

The figure people misread is land area. Census land area excludes water, so a municipality with a lake or a river frontage looks smaller in the table than it does on the map. Hiawatha is the clearest case here: its boundary encloses 751.34 square kilometres but only 718.44 of that is land, leaving 32.9 as water. If you are measuring something that sits on the ground, use the land figure. If you are measuring something that follows the boundary, use the polygon.

What this county is made of

Schoolcraft County holds 8 townships, 1 city. Hiawatha is the largest by land area at 718.44 square kilometres and Manistique city the smallest at 8.31, which makes the largest roughly 86.5 times the size of the smallest. The median sits at 311.35 square kilometres, so the spread is wide but most units cluster nearer the middle than the extremes.

Manistique city is the largest by population at 2,828, about 35 per cent of the county total. Manistique city is the densest at 340.3 people per square kilometre and Seney the emptiest at 0.2, a ratio of about 1702 to one. Seney has 115 people.

Across the whole county the density is 2.7 people per square kilometre. That is the number to hold on to, because it explains the shape of the map: a few dense nodes and a long tail of thinly settled ground, with the average describing almost none of the individual units.

Where the data comes from

Boundaries come from the Census Bureau TIGERweb county subdivision layer, which is the authoritative source for municipal geography in Michigan. Land area is the Census land measurement, which excludes inland water. Population is the 2020 Decennial Census count for each municipality.

The sources are joined on municipality name, and that join is worth checking rather than trusting. The 9 land areas sum to 3,035.14 square kilometres against a published county land area of 3,035.15, which agrees to the hundredth. The 9 with published figures sum to 8,047, which is the published county total to the person.

Aerial imagery, and how it is fitted to the map

The Satellite tab pulls one metre aerial imagery from the USGS National Map. One metre means each pixel covers roughly a square metre of ground, so at full zoom you can pick out individual buildings, field boundaries and the line of a farm track. That resolution matters at this scale. The national and state maps on this site use a NASA composite at five hundred metres per pixel, which is fine for showing where Michigan sits in the country and useless for showing where a municipal line runs.

The boundaries are drawn in an Albers equal area projection fitted to this county, with standard parallels set inside its own latitude range. Equal area matters here because the map is shaded by area: if the projection distorted area, the shading would be lying. The imagery arrives in Web Mercator and is reprojected to match.

A check you can repeat on paper

Take Manistique city. Its land area is 8.31 square kilometres and its 2020 population is 2,828. Divide 2,828 by 8.31 and you get 340.31 people per square kilometre, which is what the panel shows rounded to 340.3.

Now check it against the county. Manistique city holds 35.1 per cent of the 8,047 people on 0.3 per cent of the 3,035.14 square kilometres. That gap between population share and land share is the whole story of the map in one comparison.

Mistakes that catch people out

Reading polygon area as land area. The map draws boundaries, and boundaries include water. This county encloses 3,157.72 square kilometres of polygon against 3,035.14 of land, so 122.58 is water, about 3.9 per cent.

Assuming a city is bigger than a town. In Michigan those words describe charter type, not size. Manistique city is the smallest unit here at 8.31 square kilometres.

Expecting the average to describe a unit. At 2.7 per square kilometre the county average sits between Seney at 0.2 and Manistique city at 340.3, and matches neither.

Assuming municipal lines follow roads or rivers. Many were surveyed as charter grants or survey townships long before the roads existed. The straight lines on this map are the original survey, not modern infrastructure.
