Does location affect our BMI? We wanted to explore if there are any disparities in the BMI of our users between the North of England, the Midlands and the South. The North and the Midlands both had an average BMI of 28.7 whereas the South had an average BMI of 27.9. The map above demonstrates this divide, with the darker colours at the top and lighter in the southern regions. Yorkshire is a slight anomaly, with a lower average percentage of overweight users than its surrounding regions.
