Cotton production developed into the dominant economic activity around the city during the 1940s, so Tahoka developed a commercial economy based on service to the cotton farmer, including a comparatively large cotton-ginning industry. Its agricultural economy remained relatively stable, though the city suffered somewhat during the agricultural depression of the 1980s. In 1990 the population of Tahoka was 2,868.
