<p>Is there a map that shows the average oxygen concentration in the atmosphere? Seems to me that it would be where the most plants are but I wonder if population and industry make a difference in oxygen levels in a given area? </p>

Most sources and sinks of O2 at short timescales are associated respectively with sinks and sources of CO2. Therefore, you can take a map of CO2 concentrations (of which there are many) and the areas with minimum CO2 are most likely the ones with maximum O2
