california.

Explanation:

During the Great Depression, the Dust Bowl (centered in Oklahoma, Texas, etc.) caused severe agricultural collapse, so people fled those areas. Many displaced farm workers migrated to California, where there was demand for labor in the state's agricultural sector. Commercial farms were not a specific destination region, and Oklahoma was part of the devastated Dust Bowl area people left from.
