Document Summary
Population geography: the study of the spatial expressions of population. What was the global population (approx. ) in 1998. 1. 4 billion people in your lifetime: 210,000 per day. Population growth rate = 1. 2% (1. 13% in 2015) per year. Beyond simple growth, the key issues are: differential (unequal) population growth. ~10% of births in more developed world: the consequences of this growth: Concentrated population (examples: north america, as in the united states) Recall: the (cid:449)orld is di(cid:448)ided i(cid:374)to (cid:862)ha(cid:448)es(cid:863) a(cid:374)d (cid:862)ha(cid:448)e (cid:374)ots(cid:863) (cid:449)ith respe(cid:272)t to e(cid:272)o(cid:374)o(cid:373)i(cid:272) a(cid:374)d so(cid:272)ial development. The most populous countries tend not to (cid:271)e part of the glo(cid:271)al (cid:862)(cid:272)ore(cid:863) Recall: population density the number of people occupying an area of land. Arithmetic (crude): # of people per unit area of land. Physiological: # of people per unit area of arable land (land that can be used for food production) Are there limits to population growth, population density, and the capacity of the earth to support out population.
