Ethnic migration Weed's historic
lumber industry and manufacturing facilities made it a magnet for ethnic minority migration, that may not have otherwise been the case in this region of the country. A large number of Italian immigrants migrated to Weed, and other towns in southern Siskiyou County at the turn of the 20th century. While immigrants were a source of labor for the region, they were not always well treated, in fact in 1909 complaints from workers in the lumber industry reached the Italian consul. However, in time the Italian population came to be a cornerstone of Weed civic life. Many streets in the early Italian neighborhood bear names of Italian cities, such as Rome, Genoa, Como, and Venice. Annually since 1954, Weed has held the Weed Italian Carnevale in June or July, although recently dropping "Italian" from its name while maintaining the Italian spelling of carnival and the traditional
bocce ball tournaments. A large number of black-Americans migrated to Weed as well, to work in
Long-Bell Lumber Company's Weed facility after the company closed two mills in Louisiana in 1922. The company promised to advance travel expenses and provide housing for workers relocating to Weed. Immigrants locating in Weed since the 1980s have come primarily from Mexico and Laos. As a result of these migrations, Weed has a much more ethnically diverse population than Siskiyou County as a whole. Netting the Hispanic or Latino population out of Census figures for white race, Weed's white population is 60.6 percent compared to Siskiyou County at 79.5 percent using the same metric. ==Politics==
