Good Morning #Canada
You don't have to like numbers to appreciate Statistics Canada, aka StatsCan. Jean Talon could be considered Canada's first official statistician when he arrived in North America in 1665 on a mission for King Louis XIV to conduct Canada's first census in 1666. In 1918, the Statistics Act created the Dominion Bureau of Statistics, a national statistics office that ultimately would become Statistics Canada. Besides conducting the Census of Population and the Census of Agriculture every five years, StatCan has more than 450 active surveys on virtually all aspects of life in Canada. Results are published twice a month and can be accessed via The Daily web page.
One of my favourite web pages is Canada's Population Clock (real-time model). It's fascinating to watch, and our population increased by 11 while I typed this post.
