Demographic map of France. The following are represented: 
by single colours: the population densities per Metropolitan French department;
  &gt;5000/km2
  300 to 1000/km2
  150 to 250/km2
  100 to 150/km2
  70 to 100/km2
  40 to 70/km2
  &lt;40/km2

by dots: the 18 French cities which have a metropolitan area greater than 400,000 residents;
by the continuous black line: Le Havre-Marseille line (60% of French population lives east of this line)
by the dashed black line: the approximate limits of the empty diagonal.
The population densities are based on the 2007 INSEE (National Institute of Statistics and Economic Studies of France) legal population numbers. The metropolitan areas are based on the 1999 population numbers and metropolitan area delimitations.
