What a given BMI means in Mongolia

Share of adults with a lower BMI than each value, estimated from mean and SD
BMI	WHO band	Lower, men	Lower, women
20.0	Healthy weight	13%	14%
22.5	Healthy weight	26%	24%
25.0	Overweight	42%	39%
27.5	Overweight	60%	54%
30.0	Obese	76%	70%
32.5	Obese	88%	82%
35.0	Obese	95%	91%

In plain language

The standard deviation for men in Mongolia is 5.5. About two thirds of men have a BMI between 20.6 and 31.6; for women the middle two thirds run from 20.6 to 33.0. Compared with the global mean, men here are 1.6 points higher and women 2.0 points higher.

BMI does not distinguish muscle from fat, and the WHO bands were set on European populations. For South and East Asian populations the same BMI carries more health risk, which is why several countries there use 23 and 27.5 as their own cut-offs.
