A disparaging term for people from
Oklahoma originating with the 1930s Dust Bowl that drove out many poor Oklahomans to other states. The term has a connotation of "white
trash", rural-living, and poor.
It was the middle of the depression and swarms of impoverished farmers coming to already impoverished areas were not a welcome experience. "Okies" were persecuted, to the extent white citizens in
America could be, compelled to live in small communities on the outskirts of towns, including in the Central Valley of California where they were referred to as "Okievilles".
UD's definition of Okieville is lacking that particular context, the people weren't merely "white" they were specifically from
Oklahoma and the Dust Bowl region.
