The foreign-born waves, as the censuses record them

1850 — 2024

In 1900 nearly one South Bend resident in four had been born abroad: The Twelfth Census counted 35,999 people in the city, of whom 8,601 were foreign-born — 23.9 percent. The two largest streams were already the ones that would define the city's west and south sides: 3,053 natives of Poland, more than a third of all the foreign-born, and 2,402 natives of Germany. The German stream was the older one — Germans were the largest group of the 1850s, when the first factories were rising — and the Polish stream, which began with railroad section hands in the late 1860s and was fed directly by the Oliver and Studebaker works, made South Bend, in the judgment of its historian, the largest Polish center in Indiana from 1870 on. The census's parentage figures measure the full weight of that settlement: in 1900 the city held 7,106 Poles of foreign parentage — the foreign-born and their children together — one-fifth of all its inhabitants, a sum the same study records as nearly doubled by the outbreak of the First World War. The Hungarian stream ran between the two: recruited from the 1880s by the plow works, the wagon works and the railroads, it built St. Belgians, Italians, Irish, English and Swedes filled out the 1900 count in smaller numbers.

The streams stopped the way they had started, by law and by war: the First World War cut the flow, and the immigration acts of the 1920s closed it, and the foreign-born series then declined for half a century as the counted generation aged — the same arc the ancestry questions trace in the modern surveys. In the 2000 census the surviving shape of the old city was an ancestry profile: German 17.4 percent, Polish 10.6 percent (11,417 people), Irish 10.5 percent, English 5.8 percent, Hungarian 3.3 percent (3,605 people) — the grandchildren of the 1900 count, answering a different question. The foreign-born themselves by then were a new population: 6,854 people, 6.4 percent of the city, and more than half of them — 3,607 — had entered the country between 1990 and March 2000, the census trace of the Mexican and Central American migration that the modern-composition entry counts. The American Community Survey's 2020–2024 estimates put the foreign-born at 8.5 percent of the city — an estimate, printed as one — and the 2013 survey's ancestry table shows the old stock still legible within it: German 14.8 percent, Irish 10.4, Polish 8.2, Hungarian 2.4, Belgian 0.9. The communities behind these numbers — the parishes, the language press, the west-side streets — belong to the Communities and Religion sections; the population record's point is the shape of the arc: a city built by two great European streams in two generations, sealed in the 1920s, and opened again, from a different direction, in the 1990s.
