The four counts whole: 1990, 2000, 2010, 2020

April 1, 1990 – April 1, 2020

The CDP's whole enumerated life fits in four numbers: 20,241 people in 1990, 28,284 in 2000, 30,465 in 2010, and 30,337 in 2020 — a rise of 39.7 percent in the place's first counted decade, 7.7 percent in its second, and then a fall of 128 people, four-tenths of one percent, in its third. The 2020 count is a decline, and it is printed here as plainly as the volumes print it: Granger in 2020 was, by the Bureau's own enumeration, slightly smaller than Granger in 2010. No volume offers an explanation for the fall, and none is invented in this section; what the record does supply is the plateau measured from several sides in the closing articles below.

The counts by their parts: the CDP has always been enumerated as two township parts, and the parts have kept their own characters inside the one line. In 1990 the Harris part was the larger — 11,477 people against the Clay part's 8,764. In 2000 the Harris part still led, 17,978 to 10,306, and the parts as printed in the 2000 volume show two different communities sharing a boundary: the Clay part's median age was 43.6 years, the Harris part's 35.1 — a gap of eight and a half years between the place's older northern tier and its younger southern one. After 2000 the Bureau's published files stop printing the CDP by township parts at the older volumes' strength, and the parts' separate courses ride in the township article below, where Clay and Harris are counted whole.

Households, families, and houses: households numbered 6,235 in 1990, 9,184 in 2000, 10,394 in 2010, and 10,458 in 2020 — the household count rose in the decade the population fell, because the households themselves kept shrinking: 3.22 persons per household in 1990, 3.06 in 2000, 2.93 in 2010, and 2.90 in 2020 (the 2020 figure computed from the redistricting file's own cells: 30,290 people in households in 10,458 households). Housing units numbered 6,375 in 1990 (by the township parts), 9,401 in 2000, 10,757 in 2010, and 10,816 in 2020; the vacant share crept from 2.3 percent of units in 2000 to 3.4 percent in 2010 and 3.3 percent in 2020. Families — the census's own household category — were 91.0 percent of households in 1990, 89.0 percent in 2000, and 85.2 percent in 2010; the average family shrank alongside the household, 3.41 to 3.26 to 3.20 persons across the same three counts.
