Percentile is the share of the group with a BMI below this one. “1 in X” counts the rarer side: people at or beyond this value above the median, at or under it below. Percentiles are estimated from a normal distribution with each group's mean and standard deviation.

What this means

  • For a man of 180 cm (5 ft 11 in), a BMI of 24 is 78 kg (171 lb). For a woman of 165 cm (5 ft 5 in) it is 65 kg (144 lb).
  • Across the 186 countries in our data, a BMI of 24 is most ordinary for men in Sao Tome and Principe, where it is higher than 50% of men, and stands out most in Tonga, where it is higher than 11%.
  • BMI is weight divided by height squared. A rugby forward and a desk worker can share a number and little else, which is why doctors measure waists too.
