how many miners were in the california gold rush
California Gold Rush It is estimated that approximately 90,000 people arrived in California in 1849â€”about half by land and half by sea.[45] Of these, perhaps 50,000 to 60,000 were Americans, and the rest were from other countries.[38] By 1855, it is estimated at least 300,000 gold-seekers, merchants, and other immigrants had arrived in California from around the world.[46] The largest group continued to be Americans, but there were tens of thousands each of Mexicans, Chinese, Britons, Australians[47] French, and Latin Americans,[48] together with many smaller groups of miners, such as African Americans, Filipinos, Basques[49] and Turks.[50][51]
