3 On an average day…July 1, 2011-June 30, 2012 1042 babies born, 689 people died :. Growth of 353710 immigrants, 140 emigrants :. Growth of 570Therefore – there were 923 ( ) more people at the end of the day than 24 hours earlier!
5 That’s DEMOGRAPHY! …the study of populations We use rates to compare population growth and decline of different countries:Birth Rate (# of births per 1000 people)Death Rate (# of deaths per 1000 people)Immigration Rate (people moving in per 1000 people)Emigration Rate (people moving out per 1000 people)Net Migration (immigration rate – emigration rate)Natural Increase Rate (birth rate – death rate)Population Growth Rate (natural increase rate + net migration)
6 Concerns of growth or decline? Rapid GrowthRapid DeclineProblems providing housing, health care, jobsShortages of workers, businesses deal with a shrinking market
7 What observations can you make from the graph above? Rate calculation: (# / population) x 1000For example (Birth Rate):( / ) x 1000 = 10.3
8 Canadian Immigration: IMPORTANT! Canadian population growth is highly dependant on immigrationCanadian natural increase is lowCompare it to China (2012):birthsdeathspopulationCalculate the birth rate, death rate, natural increase
9 Compare China and Canada: What observations can you make? Natural Increase = 2/1000 (or 0.2%)Net migration = 6/1000 (or 0.6%)Pop. Growth rate = 8/1000 (or 0.8%)BR = 12.0, DR = 7.1Natural Increase Rate = 4.9
10 1. graph the data in Table 10-2 using a multiple line graph 1. graph the data in Table 10-2 using a multiple line graph. Note that the dates here are averages for 10- and 5-year periods (5 years after 1951). To graph these data you should use the middle year of the range (e.g., use 1856 for )Label “birth rate” and “death rate” on your graph. What area on the graph represents “natural increase”? Shade and label this.
11 If data existed before 1851, what values would you expect to see? Your graph shows the impact that particular historical events had on people having or not having children. Identify at least two such major events and indicate why the birth rate went up or downA) If you look carefully, you will see that the death rate has crept up slowly since By 2014, it had reached 8.3. At first glance, why does this seem odd?B) on the other hand, why should this not be surprising?4. A) If nothing changes, when do you predict that Canada’s natural increase rate will reach zero?B) what factors might change to alter your prediction? In what way will you and others your age contribute to what happens?
