Learn moreA real, disclosed income spread, but genuinely higher than Arvada or Westminster
Centennial's median household income shows a real spread across sources: one cited $114,375 (roughly 39% above the Colorado state average and 43% above the national average), a more conservative estimate cited a figure 'exceeding $102,000,' and Arapahoe County's own median was separately cited at $101,087. Even the conservative end sits close to Westminster's figure, while the higher-end reading points toward genuinely greater affluence overall -- a real, disclosed comparison rather than an assumed one.
The lowest combined sales tax rate among this dataset's three Colorado suburbs
Centennial's 6.75% combined sales tax (2.90% state + 0.25% Arapahoe County + 2.50% city + 1.10% special district) runs meaningfully below Arvada's 7.96%-9.15% and Westminster's 8.75%-9.0% -- a real, structural cost advantage on everyday purchases.
Rent readings genuinely disagree, with one notably higher figure
One source cited the average apartment rent at $2,043; a second cited $2,063 (up 2.17% year-over-year); a third, notably higher figure cited $2,897 -- a real, wide spread across sources, disclosed rather than picked, though even the lower end runs above the rent figures documented for Arvada and Westminster in this dataset.
Colorado's flat 4.40% state income tax applies here as it does statewide
Colorado levies a flat 4.40% state income tax for 2026 (subject to a TABOR surplus-refund mechanism) -- identical to the rate documented for Arvada and Westminster in this same batch.
Key takeaways
- Median household income shows a real spread ($102,000-$114,375) but genuinely trends higher than Arvada's ($117,348 -- close on some readings) and Westminster's ($100,272-$102,456).
- Centennial's 6.75% combined sales tax is the lowest of the three Colorado Tier A suburbs built in this batch.
