Oregon's growth has flattened. The population rose from 2,858,547 in 1990 to 4,243,544 in 2020, then added only about 30,000 more by 2025, to 4,273,586. The estimate dipped in 2022 (4.25 million) before inching back up. That is a sharp slowdown for a state that gained 24.6 percent from 2000 to 2025.

Across the full period Oregon is up 49.5 percent, and 11.4 percent since 2010. The state climbed from 29th among the 50 states in 1990 to 28th in 2000 and 27th in 2010, and it has held 27th through 2025. The data are Census Bureau resident estimates for July 1, and 2025 is the series high.
