Thornton Township has a predominantly African American population
Thornton Township is dominated by an African American population, with a growing Latino presence in Calumet City, Harvey, and Dolton. South Holland has a significant Dutch American and African heritage. Lansing is more mixed.
The majority of the approximately 150,000 township residents are African American, reflecting the historical migration of Black families from Chicago to the southern suburbs between the 1960s and 1990s. Dolton, Harvey, Phoenix, and Riverdale are more than 80% Black. This profile gives the area a clearly defined cultural identity.
South Holland has a distinctive profile: a historic Dutch American community (Reformed churches) with a more recent substantial African American presence. Lansing is more balanced, with non-Hispanic whites still numerous and a growing Hispanic population. Calumet City and East Hazel Crest have large Latino communities, primarily Mexican.
English predominates. Spanish is spoken widely in Calumet City and nearby neighborhoods. African American Baptist churches, AME congregations, Pentecostal churches, and Latin Catholic parishes form the religious foundation. Brazilian communities are small, spread across construction and service industries.
