In the past few years, the city of Toronto has risen in several prominent global rankings.
Liveability. In 2014, The Economist ranked Toronto the fourth most liveable city in the world on its annual "liveability index". The index considers 30 factors related to things like safety, healthcare, educational resources, infrastructure and environment in its assessment of which cities around the world provide the best or the worst living conditions.
Population. With the annual population growth rate rising steadily over the past decade, Toronto officially became North America's fourth largest city in 2013. According to the National Post, Toronto narrowly edged out Chicago in the rankings. While Toronto had an estimated population of 2,791,140, Chicago was not far behind with an estimated population of 2,707,120. However, if the ranking included each city's metropolitan areas, rather than just the city proper, Chicago would outrank Toronto by several million people. The top three populated cities in North America are Mexico City, New York and Los Angeles.
