  2. Demographics – population characteristics • P2 = P1+B-D+I-O • P2 = Total Population at any time • P1 = Census Population • B = births • D = deaths • I = In migration • O = Out migration

  3. CBR • Crude Birth Rate • Annual live births/1000 people • World Average: 20/1000 • Highest: Niger, 51/1000 • Lowest: Japan, 7/1000 • U.S. – 8/1000 • Why Regional differences?

  4. CDR • Crude Death Rate • Annual deaths/1000 people • World Average: 8.63/1000 • Highest: Swaziland, 31/1000 • Lowest: United Arab Emirates, 2/1000 • U.S. – 8/1000 • ?? Germany – 12, Mexico - 5

  5. RNI • Rate of Natural Increase • CBR-CDR…This equals population increase • Highest: Sierra Leone, 4.54% • Lowest: Russia, -.8%

  6. IMR • Infant Mortality Rate • Deaths aged 1 yr. or less/1000 live births • World average: 42 • Highest: Angola, 180/1000 • Lowest: Sweden, 2/1000 • U.S. – 6/1000 (ranks 47th) • What can this tell us about a country?
