After reading this post at GNXP on obesity rates, I plotted obesity rates (2005) versus walking rates (2000) for 15 EU nations. The negative correlation is not surprising, but what is odd is that the three outliers for obesity (UK, Greece and Luxembourg) seem to form a linear regression by themselves, and the other nations cluster at a much lower level of obesity, with also a clear linear regression amongst themselves. [Update: Replaced original graphic with labelled graph. The cluster of three countries with overlapping labels consists of Spain, Germany and Ireland.]
I wanted to plot similar statistics for more countries, specifically to find out why Canada has much lower obesity rates than other English-speaking countries (UK, US, NZ, Australia). But I couldn’t find more statistics on walking.
