  3. Fast Facts of Canada - (stats Canada) • By 2034 Canada can reach anywhere between 40 and 47 million people. • Life expectancy of a new born in Canada for a male is 78; girl 83. • In 2006, nearly 80% of Canadians were living in urban areas. • 2001 to 2006, seniors • increased by 11.5% while • children declined by 2.5% • (under 15).

  5. World Fast Facts Every second 5 people are born and 2 people die. About half of the population are under age 25. 1 in 10 people lived in cities in 1900. By 1994 that figure had grown to 1 in 2. Christian (33%) and Muslim (22%) are the most practised religion Arabic, Chinese, English, French, Spanish, and Russian are the mother tongue or Second language for about half of the world`s population. As of 2009, the median age of the world was 28.4 years.

  6. Important Population Definitions Demography – the study of population and its’ changes and patterns. Population Density – the average number of people per square kilometre. Population Growth Rate – in %, refers to the speed at which a population grows per year. (ie. World = 1.092%) Birth rate – refers to the number of live births in a country per 1000 population per year. (ie. World = 19.12/1000) Death Rate – refers to the number of deaths in a country per 1000 population per year. (ie. World = 8.12/1000) Natural Increase – birth rate higher then death rate. Natural Decrease – death rate higher then birth rate. Infant Mortality Rate - # of infant deaths per 1000 live births. (World is at 41.61/1000 live births.)

  7. Definitions Continued Doubling Time - # of years required for a population to double. Overpopulation – condition where organism’s numbers exceed the carrying capacity of its habitat. Most commonly refers to the relationship between human population and its environment. Dependency load – The ratio of people under 15 and over 65 in any population, most commonly shown to reveal the strain on the working class. Population Momentum – When the rates of growth are expected to decline but the actual population members continue to grow. Why is this happening in Canada? Carrying capacity – the max number of people that a habitat can support. Total fertility rate – The average number of children each women will have in her lifetime.

  8. Hans Rosling on global population growth • Swedish medical doctor • discovered konzo, a paralytic disease • Academic and public speaker • co-founded Gapminder Foundation http://www.ted.com/talks/hans_rosling_on_global_population_growth.html

  9. Demographic Transition Model

  10. Demographic Transition Model

  11. Demographic Transition Model Activity • Use this template to fill out the DTM. • The DTM has three lines: Birth rate, • Death rate, and Natural Increase. • Label the stages and the two axis. • Identify the three lines on the bottom • right hand corner. • Use the finished product as a study • guide for your population test.
