1990: the first count, at the strength the two volumes print it

April 1, 1990 · CP-1-16 and CP-2-16

The first census to see Granger found a young, rich, schooled farm-edge suburb of 20,241 people: median age 33.9 years; a third of the population (33.2 percent) under eighteen; only 5.6 percent sixty-five or older; 97.5 males for every 100 females. The count's household portrait is of a place built almost entirely of families: 6,235 households, 91.0 percent of them families, 85.5 percent married couples, and more than half of all households (53.9 percent) raising children of their own under eighteen. Households averaged 3.22 persons and families 3.41. The count also found 135 people in group quarters, every one of them institutionalized — the Clay part's institution, whose line runs through this section's counts (176 in 2000; a nursing-facility population of 35 in 2020) as the census's own categories change around it.

The sample volume (CP-2-16) prints the texture the short count cannot: this was already one of Indiana's most educated populations — 93.3 percent of adults twenty-five and over had finished high school and 40.9 percent held a bachelor's degree or more — and one of its most settled: 58.7 percent of the native-born had been born in Indiana, yet half the population (50.5 percent) had lived in a different house five years before, and one resident in five had arrived from another state or abroad in those five years. Foreign-born residents were 3.5 percent of the population. Just 5.2 percent spoke a language other than English at home. The labor numbers print a commuter suburb at the end of the farm era: 73.1 percent of adults in the labor force (86.3 percent of men, 60.2 percent of women); 92.1 percent of workers driving alone to work and 0.4 percent on public transit; a mean trip of 20.1 minutes; and an occupational order led by managerial and professional work at 43.2 percent of the employed, with farming, forestry, and fishing down to 0.3 percent. Incomes, in the 1989 dollars the census collected: median household income $56,149, median family income $58,140, per capita income $21,647 — against a poverty rate of 1.2 percent of all ages and 0.5 percent for children.
