A place the census invented in 1990: the frame and the counting rules

1990–2026 · Clay and Harris townships, St. Joseph County

Granger has no mayor, no council, and no boundary of its own making: every number in this section is counted inside a line the Census Bureau drew. The Bureau first delineated Granger as a census-designated place for the 1990 census, and it has redrawn the line's measurements at every census since: the place the 2000 census measured covered 26.22 square miles of land, the 2010 Gazetteer file measures 25.567, and the 2020 Gazetteer file measures 24.692 — the conflict the Story of Granger section prints at headline strength (26.2 against 24.68) is a conflict of vintages, not of arithmetic, and this section never silently normalizes it. Every density below is printed on the land area of its own census, with the basis named.

The line crosses two civil townships and belongs to neither: the CDP is built out of the southern part of Clay Township and the northern part of Harris Township (county subdivision codes 13222 and 31558 in St. Joseph County, 18141). The two townships are the older and larger frame — Harris organized January 5, 1836, Clay detached from it in 1840 (the formation record is Before the City's, at frame strength there) — and their full counts, which this section carries back to 1850, always exceed the CDP's, because each township also holds ground the CDP line leaves out: Clay's western miles carry the Notre Dame–South Bend edge, and a strip of Harris's south lies inside Mishawaka's orbit and, in the 2000 census, 1,895 Harris residents were counted inside Mishawaka city itself. The ZIP Code 46530 is not the CDP either; the postal boundary reaches east into Elkhart County, and no figure in this section is a ZIP figure.

How a designated place gets counted: a CDP is recognized only at the decennial census and in the American Community Survey's five-year estimates. The Bureau publishes no annual population estimates for places of this class — its QuickFacts sheet for Granger carries the line "Population estimates, July 1" as not applicable — so between censuses the only official course is the ACS, whose figures are survey estimates and are printed as estimates in this section, with their survey years and margins where the tables give them. The decennial counts themselves are enumerations as of April 1 of each census year, and where this section quotes a census's own published profile of itself, the profile is named; where it quotes the Bureau's redistricting file, the file is named. Nothing here is carried from an aggregator's republication where the volume or the Bureau file could be reached.
