2010: 30,465 — the high-water mark

April 1, 2010 · 2010 Census Demographic Profile (Summary File 1)

The third count is, so far, the place's maximum: 30,465 people; a median age of 40.8 (men 40.5, women 40.9); and the broadest age structure in the record — 2,876 children aged ten to fourteen, the largest five-year band in the place, with 2,779 residents in their late forties behind them. Children under eighteen numbered 9,013 (29.6 percent) and the population sixty-five and over 3,332 (10.9 percent) — the aging that the first count's 5.6 percent promised, arriving on schedule. The Bureau's published profile prints the density as 1,190.0 persons per square mile; computed on the 2010 Gazetteer file's land area (25.567 square miles) the same count gives 1,191.5 — both bases print here, per this section's rule, because the profile and the Gazetteer file are different Bureau products with slightly different land measurements.

The household record at the peak: 10,394 households; average size 2.93; 8,855 family households (85.2 percent), of whom 7,953 were married couples; 1,539 nonfamily households, 1,269 of them a person living alone, and 563 householders sixty-five or older living alone. Households containing a child numbered 4,458; households containing someone sixty-five or older, 2,253. Of 10,757 housing units, 363 stood vacant (89 of them for seasonal or recreational use); 10,069 occupied units were owner-occupied (96.9 percent) and 325 rented — the rental remnant had shrunk to 949 people in a place of thirty thousand. Relationship lines close the count: 30,453 of the 30,465 lived in households, and the group-quarters population had fallen to 12, all of them noninstitutionalized — a figure the next census's file would partly reverse, and which prints here exactly as the profile prints it.
