Roosevelt County, NM

Settlement & growth (pre-1960)

Before American settlement, the High Plains of eastern New Mexico were part of the vast territory roamed by the Comanche and Apache nations, who followed the bison herds and resisted Spanish and later Mexican incursions. The region was never densely settled by these groups, serving instead as a seasonal hunting ground. Spanish and Mexican land grants did not extend this far east, leaving the area largely unclaimed by European powers until the mid-19th century.

The first permanent American settlers arrived in the 1880s and 1890s, drawn by the promise of cheap land and the expansion of the railroad. The Chicago, Rock Island and Pacific Railroad reached the area in 1899, establishing the town of Portales as a shipping point for cattle and later for agricultural goods. These early settlers were overwhelmingly Anglo-American homesteaders from Texas, Oklahoma, and the Midwest—many of them of Scots-Irish and English descent—who came to farm dryland wheat and corn and to raise cattle on the open range. The town of Portales was officially incorporated in 1909, and the surrounding communities of Elida (founded 1908), Floyd (1910), and Causey (1910) grew as agricultural service centers for the surrounding homesteads.

A significant demographic shift began in the 1910s and 1920s, when Hispanic families from the Rio Grande Valley and northern New Mexico began migrating eastward into Roosevelt County. These were primarily Spanish-speaking Catholic families of mixed Spanish and Pueblo Indian ancestry, seeking work as farm laborers and sharecroppers on the expanding cotton and dairy farms. They settled in the southern and western parts of the county, particularly around Portales and the small unincorporated community of Lingo, forming the foundation of the county’s enduring Hispanic population. By 1930, Hispanic residents made up roughly 20% of the county’s population.

The Dust Bowl of the 1930s hit Roosevelt County hard, causing many Anglo homesteaders to abandon their farms and move to California or to urban centers. However, the population stabilized and even grew slightly during the 1940s and 1950s, as the dairy industry expanded and the establishment of Eastern New Mexico University in Portales in 1934 brought a modest influx of faculty and students. The county’s population peaked at around 20,000 in the 1950s, then began a slow decline as agricultural mechanization reduced the need for farm labor.

Modern era (post-1965)

The post-1965 period, shaped by the Hart-Cellar Act, brought only modest demographic change to Roosevelt County compared to urban New Mexico. The foreign-born population remained low—5.0% in the most recent data—and the county did not experience the large-scale immigration from Latin America or Asia that transformed other parts of the state. The Hispanic population grew primarily through natural increase and continued migration from other parts of New Mexico and Texas, rather than from new international arrivals. By 2020, the Hispanic share had risen to 44.4%, while the non-Hispanic white share had fallen to 48.9%.

The East/Southeast Asian population (0.4%) and Black population (0.9%) remain negligible, concentrated almost entirely in Portales, largely connected to Eastern New Mexico University’s faculty and student body. There is no significant Indian subcontinent population (0.0%). Domestic migration patterns have been dominated by out-migration of young adults seeking jobs in larger cities, offset by some in-migration of retirees and remote workers attracted to the low cost of living and rural lifestyle. The county’s population has been essentially flat since 2000, hovering between 18,000 and 20,000.

Suburbanization has been minimal; the only notable growth area is the fringe of Portales, where a few new subdivisions have been built for commuters who work in Clovis (Curry County) or at Cannon Air Force Base. The smaller towns of Elida, Floyd, and Causey have continued to lose population, with many of their remaining residents being elderly Anglos and Hispanic families who have lived there for generations.
