Body mass index (BMI) is a tool for measuring obesity. For an individual, BMI, computed by dividing weight (in kilograms) by height squared (in meters), can be used to classify people into weight categories (underweight, normal weight, overweight, obese, morbidly obese). For example, individuals with BMI below 18.5 kg / m2 are typically considered underweight, while individuals with BMI above 25 kg / m2 are considered overweight and individuals with BMI over 30 kg / m2 are considered obese. National average BMI values can provide insight into obesity trends across the national population.
Our research suggests that national driving habits and food consumption are associated with national average BMI in the United States. If you enter your height and weight below, along with your driving habits (in annual miles driven) and caloric intake (in daily food calories, also called kilocalories), this page will compute both your personal BMI for your height and weight, and estimate the national average BMI for an average person like yourself.
