Demographics...

Some questions I have about demographics are how do they attain all this information. Do they use online sources or do they go to peoples houses? Other than that they make things fairly straight forward so I do not have any other questions.

This demographic showed me how there really are more boys then girls in San Diego. There is a lot more from the ages 1 to 50 but after that the number starts switching and there are more girls that makes me think... do girls live longer than guys and if they do... what causes them to live so long. Maybe girls are holding out on us and know ways to live longer but they just don not want to share it with us.
