How do you calculate the density of people per square mile?

Answer 1

lay out a grid pattern 1 x1 mile and then have the people in each 1 x 1 grid raise their hand. then fly over in a helicopter with binoculars and a paintball gun. as you count the people shoot them with a paintball to mark them as counted. after you are done counting for a 1 x1 mile grid, write it in a log book. that is people per square mile. repeat as necessary. if the people are in a thickly wooded area, may first need to use defoliant like agent orange.

Answer 2

take the amount of people in the area and divide that by the total land mass of the area.
