Delaware's population mainly consisted of people from the British Isles, African slaves, Germans and a few remaining Native Americans during the colonial era. Irish, Germans, Italians, Poles, and Russian Jewish immigrants were attracted by the industries in the Wilmington area. In the late 20th century a Puerto Rican community formed in Wilmington. Guatemalan people migrated to Sussex county to work in Delaware's poultry industry. A group of Native Americans in Delaware of mixed ethnicity, the Moors, live in Cheswold. The descendants of the Nanticoke people live around Millsboro. There is also a small numbers of Asians in New Castle county who work as scientific and engineering professionals.<ref>{{Cite web|url=https://www.britannica.com/place/Delaware-state/Climate|title=Delaware - Humid, Temperate, Coastal &#124; Britannica|website=www.britannica.com}}</ref>
