The city was founded in 1906 by W. F. Holt and C.A.

The modern city is home to retail, transportation, wholesale, and agricultural industries. There are also two international border crossings nearby for commercial and noncommercial vehicles. El Centro's population was 42,598 at the 2010 census, up from 37,835 in 2000.
