A railroad town on farm country
Casa Grande was founded in 1879 because of the Southern Pacific Railroad and incorporated in 1915. Cotton and dairy farms shaped its economy, and its name comes from the Casa Grande Ruins, which actually sit in neighboring Coolidge. Interstates 8 and 10 both serve the city, and the proposed Interstate 11 would begin here.
The city grew from 53,658 people in 2020 to an estimated 69,753 in 2025, per the Census Bureau. Lucid's manufacturing plant opened here in November 2020. Growth means land clearing, pads, utility trenches and pools.
