Environment and Population (Cont.)
! World population – Factors influencing the global population: Deaths
•!World crude death rates (measures the rate of deaths for every one thousand people in a
given population, such as a country or the globe) has been falling for several decades because
of increased health, medicine.
•!So…deaths have slowed. This has contributed to the global population growth as much as
fertility rates (arguably more).
! Life expectancy
•!Japan 82.12 2009 est.
•!Canada 81.23 2009 est.
•!France 80.98 2009 est.
•!Norway 79.95 2009 est.
•!United States 78.11 2009 est.
•!India 69.89 2009 est.
•!Kenya 57.86 2009 est.
•!Somalia 49.63 2009 est.
•!Malawi 43.82 2009 est.
•!Zambia 38.63 2009 est.
•!NOTE: The low numbers in some countries are a function of high infant mortality rates.
•!When you see these really low numbers, people in some of these countries down at the
bottom they don’t necessarily die in their late 30s – there is just a really high infant mortality
so it’s really bringing the average down. If that’s the case, it really can bring the average
down, even for the entire population
! World population
•!Population growth will occur unevenly around the world
•!The vast majority in the vast population is living in poorer countries
o!Most developed nations will experience zero or even negative growth
o!Livi-Bacci (1992) predicts developing countries will account for approximately 95%
of the world population by 2050.
"!Developed Countries Today (about 1.2 billion people – 17% of the global
population):
"!Europe – 730 million
"!U.S. – 312 million
"!Japan – 128 million
"!Canada 34 million
"!Australia 23 million
! Projected annual growth rate of country populations, 2010-2050
•!Explosion of the population will take place in the poorest parts of the world
o!Biggest population expansions
Document Summary
This has contributed to the global population growth as much as fertility rates (arguably more). India 69. 89 2009 est. bottom they don"t necessarily die in their late 30s there is just a really high infant mortality so it"s really bringing the average down. If that"s the case, it really can bring the average down, even for the entire population. Developed countries today (about 1. 2 billion people 17% of the global population): Projected annual growth rate of country populations, 2010-2050: explosion of the population will take place in the poorest parts of the world o biggest population expansions. Why were we growing so slow for most of human history? o deaths were outpacing births! o no medicine, no vaccines: biggest drivers of drops in deaths rate: o vaccines and antibiotics. The demographic transition: refers to a shift in demographic pattern from high birth and death rates to low birth and death rates o occurs parallel to a society"s socio-economic development.
