UPDATE: Estimates for Sunday's Paris march attendance have soared higher, with some outlets reporting as many as 3 million people swarmed the heart of the French capital to support free speech.
The Associated Press reported that around France, up to 3.7 million people marched on Sunday — which could mean more than 1 in 20 French, 5.6 percent of the nation's population, had taken a public stand.

What do those numbers mean in context?
Sunday's march was enormously larger than some of America's biggest protests — even more so when you account for the size of the country.
Given France's population of 66 million, 1.5 million marchers could mean nearly 2.5 percent of the entire country's population participated in the march — though plenty of foreigners converged on the French capital to rally as well.
By comparison, the famed November 1969 march against the Vietnam War, heralded as the largest anti-war march in American history, drew roughly half a million protesters, less than 0.3 percent of the then-202 million-strong U.S. population.
Of course, at 1.5 million, the French march isn't just bigger on a percentage basis — it's bigger in absolute terms than the 2013 March for Life and the 1969 Vietnam protest combined.
