The plateau, measured: the current state as of the newest counts

2010–2026 · printed November 2026

The newest state of the place is a plateau with the edges still moving: the CDP fell by 128 people between the 2010 and 2020 censuses (30,465 → 30,337) and the 2020–2024 survey estimates it at 30,321 — statistically the same place, counted three ways. The plateau is not uniform inside the frame: across the same decade Harris Township grew 4.0 percent (23,454 → 24,397) and Clay Township 5.2 percent (32,550 → 34,235), so the growth of the 2010s happened in the townships' ground outside the CDP line while the delineated place itself stood still — the arithmetic of a boundary drawn around a built-out suburb, printed here as arithmetic and nothing more. The record reached offers no official explanation for the stall, and this section prints none; it prints the measurements instead.

The measurements: the median-age course — 33.9 (1990), 37.8 (2000), 40.8 (2010), 41.3 (2020 census), 40.4 (2020–2024 survey) — is a place aging roughly a year per calendar year at the end of its building era, then leveling. The child share fell from 33.2 percent of the population in 1990 to 26.7 percent in 2020; the sixty-five-and-over share rose from 5.6 percent to 10.9 percent by 2010 and to an estimated 18.1 percent in the current survey. Households kept forming after the population stopped growing (10,394 in 2010; 10,458 in 2020; an estimated 10,560 in the survey) because households kept shrinking (2.93 persons in 2010; 2.90 in 2020). The housing stock dates the stall independently: 262 of 10,869 units — 2.4 percent — were built in 2010 or later, against 5,384 (49.5 percent) built in the two decades 1980–1999 alone. Density stands at 1,228.6 persons per square mile on the 2020 Gazetteer land area of 24.692 square miles — the densest reading in the record, and, on the area conflict this section prints whole in its first article, a figure whose basis (24.692, not 2000's 26.217) must travel with it.

What would change the reading: the 2030 census is the next enumeration of the place, and the survey vintages between now and then are the only official course there is. The Microsoft campus rising on the old farm ground at the frame's east (the Story of Granger section carries the project) is the largest single land-use change inside the line since the subdivisions; whether it moves the next count is a question the next count will answer, and this section leaves it there.
