In recent decades, body mass index (BMI) has been rising globally due to many societal changes, including changes in eating and physical activity habits. Using data from the United Nations (UN) and the World Health Organization (WHO), the London School of Hygiene and Tropical Medicine calculated the average BMI for 177 countries and created a tool that enables you to see where your BMI fits in compared with individuals in your own country and others.
The calculator is available through the BBC.
