This time can be approximated by dividing 70 (more accurately by 72) by the percentage growth rate. Doubling time = 70/0.9 = 78 years Thus if the growth rate remains constant, Canada s population would double from its 2006 population of 33 million to 66 million by the year", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
