Implosion/Explosion Scenarios

Implosion Examples (the rapid decrease of population due to decreased birth rates) EUROPE AS A WHOLE WILL PROBABLY LOSE ABOUT 20 MILLION PEOPLE OVER THE NEXT 40 YEARS

As an example: Italy’s fertility rate fell to.9809 in 2005 (1.38 in 2010) ITALY WILL LOSE ABOUT 28 PERCENT OF ITS POPULATION

Population Trends Continued: More Developed/Less Developed Growth Contrast Uganda and Canada, which currently have about 34 million and 31 million residents, respectively. By 2050, Canada's population is projected to be 42 million, while Uganda's is expected to soar to 96 million.

Population Shift to Cities

Urbanization In 2004 approximately 51 percent of the world’s population lived in metropolitan areas In 2004 approximately 51 percent of the world’s population lived in metropolitan areas By 2020 the rate of urban growth will be four times that of rural growth By 2020 the rate of urban growth will be four times that of rural growth

Percent of Total World Population Living In Rural Areas Rural 2050 Rural 2030 Rural 2020 Rural 2090 Rural Now

Growth of Metropolitan Areas (Number of Cities with 1 million or more people) cities cities cities (2/3’s are in developing nations) cities (2/3’s are in developing nations) 2010 estimates indicated there were 368 cities of 1 million or more in the developing world alone estimates indicated there were 368 cities of 1 million or more in the developing world alone. Growth of cities will continue to be greatest in the developing world For example:… Growth of cities will continue to be greatest in the developing world For example:… Lagos, Nigeria has grown from 300,000 in 1950 to an estimated 21+ million residents today.
