Composition, as each census printed it

1850–2024 · the categories are the censuses' own

The place's printed composition begins as a single line: in 1850 the townships were returned as entirely white (the county's 29 free colored residents lived elsewhere in it, as the township article prints), and for most of the record the counts that follow barely move. At the CDP's first count in 1990, residents returned as White alone were 19,548 of 20,241 (96.6 percent; 19,426 of them not of Hispanic origin), and Asian or Pacific Islander residents — the 1990 census's own combined category — were 411.

From 2000 the diversification prints decade by decade, in the censuses' own categories: White alone falls from 94.1 percent (26,629) in 2000 to 90.3 percent (27,512) in 2010 to 82.4 percent (24,996) in 2020. The Asian-alone count rises 745 → 1,403 → 1,906, and the 2010 profile names its parts: Asian Indian 466, Chinese 403, Korean 179, Filipino 91, Vietnamese 62, Japanese 39, other Asian 163. The Black-alone count rises 493 → 773 → 1,003. Hispanic or Latino residents rise 341 (1.2 percent) → 733 (2.4 percent; of Mexican origin 410, Puerto Rican 79, Cuban 20) → 1,217 (4.0 percent), and the survey record carries the line to 1,658 (5.5 percent) in 2020–2024. The two-or-more-races count makes the largest proportional move in the record: 302 (1.1 percent) → 499 (1.6 percent) → 1,883 (6.2 percent). The immigrant strand, at the strength the surveys count it: foreign-born residents were 3.5 percent of the place in 1990, and in the 2020–2024 survey 2,419 residents (8.0 percent) were foreign-born — 1,458 of them naturalized citizens — with Asia the largest region of birth (1,336), ahead of Europe (394); of the native-born, 16,703 were born in Indiana and 10,720 in another state. The survey's ancestry table (single-ancestry reports) prints the older layers of the same story: German 8,184; Irish 5,794; English 3,781; Polish 2,096; Italian 1,665; American 1,189; Hungarian 486; Belgian 389; Dutch 469; and Arab 301, of whom 236 Lebanese.
