Boulder, CO

Boulder’s median household income was $80,243 in the city and $102,772 in Boulder County, while the county assessor notes residential property is reappraised on a regular county schedule and assessed at a 7.05% school-district rate for 2025 and 2026 (Census QuickFacts^[1], Boulder County Assessor^[2]). Colorado has a flat state income tax, and Boulder County’s assessor pages confirm property taxes are administered locally rather than at the state level (Boulder County Assessor^[3]). Official sources confirm Boulder’s city and county tax mechanics, but a current official grocery-price index and a city-specific median home price are not given here.

Boulder Community Health is the main local hospital system in Boulder, with the CMS Care Compare hospital listing at 4747 Arapahoe Avenue in Boulder (Medicare.gov Care Compare^[4]). The hospital’s location and Medicare quality context are confirmed, but a drive-time map and specialty-service directory are not given here. For retirees, the practical takeaway is that Boulder can handle routine and many acute needs locally, while higher-complexity subspecialty care is often sought in the larger Denver metro.

NOAA Boulder climatology pages show summer average highs around the low to mid-70s Fahrenheit and winter average lows in the 20s to low 30s Fahrenheit, with annual precipitation on the order of roughly 14 to 20 inches depending on the Boulder station used (NOAA PSL Boulder climatology^[5], NOAA monthly means^[6], NOAA monthly precipitation^[7]). The same NOAA pages show Boulder gets many 90-degree days concentrated in June through August, and snowfall is seasonal rather than constant (NOAA days at or above 90F^[8], NOAA snowfall totals^[9]). That makes the best outdoor season long, especially spring through fall, with winter still usable for many days if you are comfortable with occasional snow and temperature swings.

Boulder County’s county-level FBI-derived summary reports violent crime at 50.9 per 100,000 residents, 52.1% below the national average, and property crime at 159.8 per 100,000, 2.3% below the national average (CrimeExplorer Boulder County^[10]). Boulder County recorded 9,536 violent crimes and 29,872 property crimes across the five-year period shown, but the source text does not establish a clean 3-year trend line from the FBI Crime Data Explorer. So the safest conclusion is that Boulder County looks relatively safer than the U.S. on violent crime, while property crime remains a material watch item for residents and retirees.

A drive time or nonstop route list for Boulder is not given here. The practical reality for Boulder residents is that Denver International is the major commercial airport used for most domestic and international travel, with Boulder functioning as a Denver-area suburb for air access. If you need a precise drive time and current nonstop hub map, that should be confirmed on an airport or airline schedule page before making the move.

The city also notes that Boulder has more than 150 miles of bike-friendly infrastructure, plus a network of walking paths and trails, and its downtown and trail system are part of the everyday recreation pattern (City of Boulder Transportation and Mobility^[17], City of Boulder Walk^[18]). For a retiree who wants golf plus hiking, biking, and mountain access, Boulder is unusually well rounded even without a big roster of private clubs in the immediate core.
