Colorado's Forgotten Corner: High Inequality, Surprising Ownership, and Life at the Edge of the Sangre de Cristos

Costilla County sits in Colorado's far southern San Luis Valley, tucked against the New Mexico border and the Sangre de Cristo Mountains. It is one of the oldest settled counties in the state — Spanish land grant families established roots here before Colorado was even a territory — and that deep history helps explain why this place doesn't behave like a typical rural American county. The data here tells a story of entrenched poverty alongside remarkable self-sufficiency, and a housing market shaped less by investment capital than by generational land tenure.

Key Statistics

Ownership Without Wealth

The most striking tension in Costilla County's data is the coexistence of deep poverty and high homeownership. More than three in four households own their home — a rate that surpasses the national average by a significant margin — yet median household income sits at just $36,519, less than half the U.S. benchmark. This isn't a gentrification story. It's a land legacy story. Many families here hold property passed down across generations from original Spanish and Mexican land grant settlements, meaning ownership predates the modern mortgage market entirely. You own the land because your great-great-grandparents owned the land.

That context reframes what might otherwise look like an affordability success story. Homes are cheap in absolute terms, but with incomes this low, the price-to-income ratio still creates strain for anyone trying to enter the market from the outside.

Inequality Hidden in Plain Sight

A Gini index of 0.517 is a remarkable figure for a county of just 3,571 people. For context, the United States as a whole — a country frequently cited for high inequality — scores around 0.49. Costilla County is more unequal. This likely reflects a small but significant population of higher-income remote workers and retirees who have discovered the county's dramatic scenery and low land prices, living alongside long-established households struggling with a 22.3% poverty rate and a child poverty rate of 28.2%. The county's 34.9% housing vacancy rate is a telltale sign: a large second-home and seasonal property stock that inflates the owner-occupied share while contributing little to the local economic base.

An Aging, Settled Population

With a median age of 50.7 and more than a quarter of residents over 65, Costilla is graying fast. Labor force participation at just 43.8% reflects both that age profile and a disability rate of 23.7% — well above national norms, consistent with an older rural population doing physically demanding work over a lifetime. There is no public transit. Virtually no one commutes by bus or train. The county runs on cars, trucks, and — increasingly — remote work, which accounts for 12.6% of workers, a share that would have seemed implausible here a decade ago.

FAQs

What makes Costilla County, Colorado unique? Costilla County is one of the oldest continuously settled areas in Colorado, with roots in Spanish land grant culture that predate American statehood. That heritage directly shapes its unusually high homeownership rate despite being one of the state's poorest counties by income. It's also home to the Great Sand Dunes region's southern approach and draws a small but growing contingent of off-grid landowners attracted by cheap acreage and dramatic mountain scenery.

Is Costilla County affordable to move to? On paper, yes — median home values around $171,000 are well below both Colorado's and the national median. But the local economy offers limited employment, and services are sparse. The county's SNAP benefit usage (24.6%) and rent burden figures suggest that even at these price points, many existing residents struggle. Buyers relocating with remote income or retirement savings will find genuine value; those depending on local wages face a much harder calculus.

Why is the vacancy rate so high in Costilla County? Much of Costilla County's vacant housing stock consists of seasonal cabins, undeveloped land parcels with structures, and second homes clustered around areas like Fort Garland and the mountain foothills. A significant amount of land in the county was also sold in large subdivided parcels during mid-20th century land promotions, leaving scattered, sometimes unoccupied lots with modest dwellings that sit empty much of the year.
