Standard oxygen concentration for earth's atmosphere is 20.9%
Theoretically, this percentage does not change at varying altitudes. What changes is the density of the oxygen (and other gases, such as nitrogen) present in the air. At sea level or on a mountain top, oxygen concentration is 20.9%
However, depending on things like air pollution and location (indoors vs. outdoors), O2 concentration can vary widely, down to as little as 10% in polluted indoor environments.
