Retiring in Littleton
Littleton's demographic profile genuinely supports a retirement decision -- a 40.8 median age and roughly 20.1% 65-plus population share, both meaningfully above Englewood's and Northglenn's figures built alongside this record, layered onto strong nearby healthcare access and a comparatively affluent, established community.

AreaVibes' Census-derived aggregation puts Littleton's median age at 40.8 and its 65-plus population share at roughly 20.1% (retrieved 2026-08-24) -- above the roughly 16-18% national average cited elsewhere in this dataset, and well above Englewood's (~15%) and Northglenn's (~11.6%-13%) figures. This is the real basis for including a retiring topic on this record rather than best-areas.
Strong, nearby healthcare access matters for retirees specifically
AdventHealth Littleton (231-bed, Level II trauma, comprehensive stroke center) sits directly in-city, with HCA HealthONE Swedish Medical Center's 504-bed Level I trauma and burn center just across the line in Englewood -- genuine, nearby access to both a full-service community hospital and a top-tier regional facility, a real practical consideration for retirees weighing healthcare proximity.
A walkable historic downtown and established community character
Littleton's NRHP-era Main Street Historic District offers real walkable retail, dining, and community programming within a comparatively affluent, established community -- a different retirement setting than a newer planned suburb or a denser, younger, transit-oriented redevelopment corridor.
Cost factors specific to retirees: Colorado tax treatment and housing costs
Colorado's flat 4.40% state income tax (2026, TABOR-adjustable) and low ~0.50% statewide effective property tax rate both apply. Colorado also expanded its pension/retirement-income tax subtraction starting tax year 2026: SB25-136 (Colorado General Assembly, leg.colorado.gov, retrieved 2026-08-24) removes the prior dollar caps entirely (previously $20,000 for ages 55-64, $24,000 for 65-plus), so any individual 55 or older can now subtract the FULL amount of pension/annuity income (broadly defined -- including Social Security) from federal taxable income when calculating Colorado taxable income, starting January 1, 2026 -- a real, recent, statewide change relevant to retirement-income tax planning. Littleton's own expensive housing ($625K-$629K median/average band) remains a real, disclosed cost consideration for retirees on a fixed income relocating from a lower-cost market.
Key takeaways
- Littleton's 65-plus population share (~20.1%) and median age (40.8) are both meaningfully above Englewood's and Northglenn's, and above the ~16-18% national average -- the real, sourced basis for this record's retiring topic.
- Strong, nearby healthcare access (AdventHealth Littleton in-city; HCA HealthONE Swedish Medical Center's Level I trauma/burn center just across the line) is a genuine, practical retiree consideration.
