Document Summary
E. g. how density populations are: what resources do they use, what are their conditions of health and well-being, using global perspective, what is the current (approx. ) global population. An increase of close to 1. 5 billion people in lifetime: what is the worlds largest (by population) country. Major thresholds and time periods: ad1=300m, 1800=1 billion, 1927=2 billion, 1960=3 billion, 1975=4 billion, 1987=5 billion, 1999=6 billion, 2012=7 billion, feb. 2013=7. 06 billion, 2050(projected)=9billion, world population: growing at 1. 2% per year. Sounds small: population will double (~14 billion) in life time. Will rate change between now and then: experts believe so, beyond simple growth, the key issues are: Where will it occur? (less develop world) E. g. of 131 million births in 2005. Only about 13 million (10%) were born in the more developed world. Global population distribution: area of clustered settlement: europe, india, china, area of dispersed settlement: africa. Global population distribution: uneven: patterns of concentrated population. 90% north of the equator (northern hemisphere)
