Demography

• is the statistical study of changes in the nature
  of a population.
• The study of the distribution, density, and vital
  statistics of populations.

Spatial Demography

• Satellite Imagery
• Pixel and Grid
• Passive Sensors
• Active Sensors

• Geographic Information System (GIS)
• Point
• Line
• Area
• Attributes
