Mainstream cultural norms are so pervasive in every aspect of society that without an active effort, indigenous values and traditions will be lost. Preserving culture often involves funding- whether it is for a theatre group, art show, language program, or other means of cultural expression. In countries like the US and Australia, indigenous groups make up less than 3% of the current population; 1;2 without assistance from the government, it is unlikely these groups would be able to sustain such cultural efforts and as a result their culture would not have any chance to evolve.  1 Race - Universe: Total Population, U.S. Census Bureau American Fact Finder, 2009. 2 Experimental Estimates and Projections, Aboriginal and Torres Strait Islander Australians, 1991, to 2021, Australian Bureau of Statistics, 2009.
