According to the U.S. Census Bureau, our city is home to 2.71 million people to Toronto’s 2.79 million in 2012.
Mexico City, New York and Los Angeles top the list.
Chicago is still one of the top 10 largest cities in North America, and the population did increase by more than 11,000 residents between 2010 and 2011. And we lead the nation in the category of cities that have experienced population growth downtown over the last decade, with an increase of more than 37,000 residents within 2 miles of City Hall, according to Chicago magazine.
Not a big difference at this point but Chicago is unlikely to get much closer in population compared to Los Angeles anytime soon, Toronto may continue to grow, Washington D.C. is growing in influence, and Houston is a ways behind Chicago but has been growing at a rapid pace in recent decades. Maybe this means Chicagoans should be a little worried about their status as a global city?
One area where Chicago does not have to worry: it is still securely ahead of Toronto in terms of its metropolitan area population. The Chicago metro area has over 9 million people while the Toronto metro area has over 5.5 million (2011 figures). Additionally, Chicago has over 2.5 million more than the next biggest US MSA, Dallas.
