Ukrainians (Ukrainian: українці, ukrayintsi) are an East Slavic ethnic group native to Ukraine, which is the sixth-largest nation in Europe. The Constitution of Ukraine applies the term 'Ukrainians' to all its citizens. Also among historical names of the people of Ukraine Rusyns, Cossacks, etc. can be found. According to some dictionary definitions, a descriptive name for the "inhabitants of Ukraine" is Ukrainian or Ukrainian people.
The Ukrainian diaspora is the global community of ethnic Ukrainians, especially those who maintain some kind of connection, even if ephemeral, to the land of their ancestors and maintain their feeling of Ukrainian national identity within their own local community.
A Ukrainian Canadian (Ukrainian: Український канадець, Україноканадець) refers to a Canadian of Ukrainian descent who is an immigrant to or a descendant born in Canada. In 2011, there were an estimated 1,209,085 persons of full or partial Ukrainian origin residing in Canada (mainly Canadian-born citizens) making them Canada's ninth largest ethnic group, and giving Canada the world's third-largest Ukrainian population behind Ukraine itself.
