GEOG 5 Lecture Notes - Lecture 8: Demographic Transition, Exponential Growth, Malthusianism
Document Summary
Lecture 8: population geography: size, composition, spatial. World distribution: most populous countries- (1)china (2) india (3) united states (4) indonesia. Highly uneven distribution: half of the worlds population lives in south east asia. 90% of the worlds population lives on 20% of earths surface. Ecumene: the portion of surface where humans live permanently (17% of the earth) C. relevant physical earth factors people live close to the ocean- continental margins people live where you can grow crops- arable land (agriculture) Climate- people don"t live in polar regions, or in the desert usually. C. growth now and in near future (cid:0) worlds population is still growing but rate has declined since 1960"s. D. demographic transition model (cid:0) 4 stages (cid:0) stage 1: high stationary, high population birth rates/death rate (cid:0) stage 2: early expanding (cid:0) stage 3: late expanding, rapid population growth (cid:0) stage 4: low stationary, fairly low birth/death rates.
