As of the 2010 Zambian census, Zambia's population was 13,092,666. Zambia is racially and ethnically diverse, with 73 distinct ethnic groups. During its colonial administration by the British between 1911 and 1963, the country attracted immigrants from Europe and the Indian subcontinent, the latter of whom came as indentured workers. While most Europeans left after the collapse of white-minority rule, many Asians remained.
