The term '1930s Migrant' refers to the large number of people who migrated to California during the 1930s, often referred to as 'Okies'. This migration was largely due to the Dust Bowl, a period of severe dust storms that caused major ecological and agricultural damage to the Great Plains region of the United States. The migrants were primarily from Oklahoma, Texas, Arkansas, and Missouri, and they sought better economic opportunities in California. The term 'Okie' is derived from the nickname given to these migrants, which was a combination of the words 'Oklahoma' and 'hickie'.
