The Rowley Mine, a private copper mine known as a source of the mineral Wulfenite, is located near the settlement. The large Paloma Ranch is located near Theba; many residents are employed on the ranch, and the area is frequently marked as Paloma on maps.
The area, which is in the Sonoran desert, was a farming area into the 1960s, and once had significant crops of melons, jojoba, and guar in the 1970s, which is used in the oil industry. The Southern Pacific Company once had a railroad station there, served by Wells Fargo. The population was estimated at 200 in 1960.

Theba Elementary School made headlines across the state of Arizona in 1977, when school administrators refused to sign a federal pledge agreeing not to discriminate against women. The school was one of the few in the country which refused to sign the agreement, disqualifying them from receiving federal funding. According to school administrators, the school refused to sign because they had never received federal funding anyway.
