  1. Population is constantly changing over time…. Dynamic Pop. is unevenly distributed… has four distinct areas: 1.Western & Central Europe 2Eastern United States & South Eastern Canada 3.Indian sub-continent… Pakistan, Sri Lanka & Bangladesh 4.East & South East Asia…. China, Korea, Japan, Philippines. These areas are in the northern hemisphere (90% pop) & in temperate or sub tropical latitudes. 2/3rds pop live 500km of coast – 4/5th live below 500m Thinly pop. areas are often too high, cold, hot, wet, dry. EG. 1. Cold Tundra… Northern Canada, Greenland, Siberia, Antarctica. 2. Mountains of Himalayas, Rockies.

  2. 3. Hot deserts …. Sahara & Australian deserts. 4. Equatorial rainforests… Amazon & Congo Physiologic density… ratio of people in a country per unit of agriculturally productive land. In India this is 650 per Km sq. Lowlands most highly populated area… fertile soils & rivers. Highlands poorly populated… thin infertile soils & rugged Migration to towns & cities has changed pop patterns as a country moves from an agric. to an industrial economy. 1950…29% of world pop urban…. 2000 = 50%. 2030 = 60% This leads to rural depop. and negative pop. growth rates. Movement to megacities… pop. over 10m… most in Asia.
