Age Distribution
The average population of the community of Mayo in 2003 was 409, showing a continual decline from an average of 503 in 1997. Prior to this, Mayo's population grew slightly at the start of the 1990s.
The First Nation of Nacho Nyak Dun, who live in and around Mayo, make up 60 to 70 percent of the community population, compared to First Nations representation of 23 percent for the Yukon overall.
Mayo has a settled multigenerational population. The 2001 Census reported that well over 80 percent of the people living in Mayo had also lived there in 1996. Fewer than 10 percent of the population had moved to Mayo from outside the Yukon in the five years prior to 2001, compared to 16 percent of the overall Yukon population.
There is a slightly larger proportion of children in the community of Mayo than in the overall Yukon population. There are more people over 65 years of age (11 percent), compared to the Yukon average of 7 percent. On the other hand, Mayo's population includes fewer people, proportionately, in the 25-to-44 age group, reflecting some earlier movement out of the area by people looking for work elsewhere.
At the end of 2003, 50 percent of Mayo's population was female, the same as the Yukon as a whole.
