The 2010 census indicates that since 1960 Mexico’s population has more than tripled to 112.3 million. However, the growth rate between 2000 and 2010 (1.4% per year) is less than half the 3.4% rate of increase experienced in the 1960s. If Mexico’s population had continued to grow at 3.4% since 1960, it would have been over 186 million by now!

Explanation:
The St. Lawrence seaway helped because it was large enough to allow shipping transportation to the USA. Which allowed Canada and the USA to trade goods. The seaway extends from Montreal through the Welland Canal in Ontario, Canada, to the eastern portion of Lake Erie.
(Have a great day!)
