The conversion, and what farms remain, as of November 2026

1940–2026 · SUBURBAN CONVERSION MEASURED AT THE RECORD'S STRENGTH

The township's west became a suburb on the town's own curve: the town of Osceola more than doubled in the 1940s (498 in 1940, 1,091 in 1950) and stands at 2,590 in 2020, its growth "by the subdivision street rather than by the factory gate" (the Story of Osceola section), and Mishawaka's annexations took parts of Penn from 1947 (the census's township footnotes, as the Story of Osceola section carries them) — the township that Chapman mapped as a wholly private farm map is today, in its western half, the town's neighbourhoods and the sister city's south side. No acreage series for the township's farmland loss stands in the record reached — the agricultural censuses print no township line — and the conversion is therefore printed measured only at its ends: a farm map entire in 1875, and a 2020 township of 68,698 people (the PL 94-171 count, as the Story of Osceola section carries it) whose seated farm enterprise of scale is one operation. False precision would be the defect here; the parcel record of the county — the instrument the Granger build used to count its surviving farm parcels — is the settler named in the closing roll for any acreage figure this section prints in future.

What remains, named: the Martin dairy farm at the township's east edge — some 600 acres in the Farmer's Exchange's 2020 count, growing its own alfalfa, corn and grass, milking about 300 cows, and since 2017 processing and retailing on the farm — is the largest working farm the record names on Penn ground today, and the only one documented at enterprise size. South and east of the town, beyond the subdivision edge, the township's farm ground continues in the pattern the census frame states for the county: fewer and larger holdings, crops at 80 percent of sales. The leg's closing fact is the frame's: a township that fed itself at a Michigan mill in 1828 ends its documented farm course, two centuries on, with its biggest farm selling its own milk in glass bottles off Ash Road — the farm and the store on one piece of ground, which is where this build's business record began, with a miller's son-in-law keeping the village store.
