As of March, 2019, the total registered population of Alexis Nakota Sioux Nation is 2036 persons. There are 508 registered males, and 459 females living on their own reserve. Members of Alexis First Nation are of the
"Stoney" or "Nakoda" ethnic group. The Stoney are sometimes considered part of the
Assiniboine. The terms "Stoney" and "Assiniboine" stem from outsider's descriptions of how those peoples cooked by using heated stones (Assiniboine originates from the
Ojibwe language;
asinii meaning "stoney" and
bwaan meaning "cooker"). The term
Sioux is also an outsider's description used by the French to describe the Dakota and Lakota Nations in the United States. The Dakota and Lakota in Canada are non-treaty First Nations. Their traditional language is
Nakoda/Stoney, and their endonym is I'sga I?abi. ==Government==
