Avondale first appeared on the 1920 U.S. Census as the 45th Precinct of Maricopa County (AKA Coldwater). In 1930, it simply appeared as the Coldwater Precinct. It was recorded as having a Spanish/Hispanic majority for that census (the census would not separately feature that racial demographic again until 1980). With the combination of all county precincts into 3 districts in 1940, it did not report on that census. In 1946, it was incorporated as the town of Avondale, and has appeared on every census since 1950.
