Originally a wealthy enclave, Uptown's entertainment and retail sectors rivaled the Loop by the 1920s when extensive apartment construction lowered rents and attracted singles from other parts of the city. Eastern European Jews and African-Americans followed, and relocated Japanese-Americans moved there during and after World War II. Native Americans and Appalachians arrived during the 1950s. Uptown faced population loss and disinvestment through the 1980s, but has remained a port of entry for working-class immigrants and refugees.
