A very sparsely populated West Texas county, Irion County has Mertzon as its seat. Established in 1889, it has always been ranching country, with sheep and cattle still central to the local economy. The county is strongly rural, with Mertzon as the only real town. Housing consists mostly of ranch houses, older frame homes, and manufactured housing. San Angelo, about 25 miles east, provides larger services. Prices are low: most homes cost $100,000–$170,000, while ranchland averages $2,000–$5,000 per acre. Buyers here are often ranchers, hunters, or those seeking quiet West Texas acreage.
