Republic of Korea weight percentile tables (P3–P97)

Republic of Korea’s published weight figures, P3 to P97 month by month, up to 10y 1m. Boys and girls separately, on the standard’s own curves.

This table spans two standards: who-cgs-2006 from 0 months, then who-gr-2007 for older ages. The numbers step at the join — that is the reference changing, not the child.

About this table

KNGC2017 uses WHO standards from birth to 35 months and Korean data from 3 years. What can be read from it is height and weight for 3–7 years. Its head-circumference series breaks between 72 and 73 months and its BMI series does not agree with its own height and weight, so neither is usable.
At 3 years, height and weight switch from WHO to Korean data, and the z-score steps up slightly because the Korean median is a little higher. That is the seam between two tables, not a change in growth.
