Olivhurst was first largely settled by people from the Midwest during the Great Depression who were looking for fertile land, availability of jobs, and a better future. People from the town have been known to refer to this group of people as Okies. These Okies were following migrant workers such as those of Chinese, Japanese, Filipino, Mexican, and Native American background.
