City, county, metro — and the city of students outside the line

2010 — 2020

Most arguments about South Bend's size are arguments about which South Bend is being counted: The metropolitan statistical area is a federal definition, revised by the Office of Management and Budget, and South Bend's has been drawn more than one way — the 1980 census's tract volume for the South Bend SMSA covered Marshall County alongside St. Joseph; the present South Bend–Mishawaka metropolitan area comprises St. Joseph County, Indiana, and Cass County, Michigan, a metro that crosses a state line to take in the Michigan suburbs the city's growth spilled into. On that definition the metro counted 324,501 at the 2020 census. The wider combined statistical area, which joins the metro to the Elkhart–Goshen and neighboring micropolitan areas, counted 812,199, and the urban area — the built-up ground itself, ignoring every jurisdiction — counted 278,921. The rule for reading any South Bend population figure in the wild follows: near 103,000 is the city at the 2020 census; near 273,000, the county; near 279,000, the urban area; near 325,000, the two-county metro; and near 812,000, the combined statistical area. Each is a true number for its ground, and none of them may be substituted for another.

One more counted place belongs in this entry, because the census's residence rule makes it part of the city's arithmetic even though no map of the city contains it: the Notre Dame census-designated place. The census counts people where they usually live and sleep — for a student, at school — so the dormitories of Notre Dame, Saint Mary's and Holy Cross are a counted population of their own, on the unincorporated ground in Clay and Portage townships outside the city line, the ground the 1969–71 annexation fight was fought over. The place was first separately counted in 2010, at 5,973; in 2020 it counted 7,234, up 21.1 percent, of whom 6,721 — 92.9 percent — lived in college dormitories, in 181 households, at a median age of 20.3 years, on 1.2 square miles. It is the mechanism, stated plainly: some twelve thousand university and college students live at the city's edge, the census counts every one of them, and it counts them outside the city, in the county balance — a counted population larger than many an Indiana town, attached to South Bend in every way except the one the tax duplicates and the census's city column record.

The boundary series: Mishawaka's counts are printed here, and only here, because the comparison is the point — it is a separate city, and its full record belongs to its own history. The two cities were near equals when both were river towns (1,412 against 1,652 in 1850); South Bend's factories made the gap; Mishawaka's own industries and its room to grow narrowed it again, proportionally, in the decades when South Bend shrank.

Together the two cities counted 154,516 people in 2020, 56.6 percent of the county — against 69.5 percent in 1960. The urban core's share of its own county fell by an eighth even as one of its two cities set its record; the difference is the townships.
