What a given BMI means in Brunei

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	9%	12%
22.5	Healthy weight	19%	22%
25.0	Overweight	34%	36%
27.5	Overweight	51%	51%
30.0	Obese	69%	67%
32.5	Obese	83%	80%
35.0	Obese	92%	89%

Read it as: a man with BMI 30 in Brunei has a higher BMI than 69% of men. Values under 1% or over 99% are shown as <1 and >99.

In plain language

The standard deviation for men in Brunei is 5.5. About two thirds of men have a BMI between 21.8 and 32.8; for women the middle two thirds run from 21.1 to 33.5. Compared with the global mean, men here are 2.8 points higher and women 2.5 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.
