The reference population used to construct the CDC Growth Charts is a
nationally representative sample. Data were obtained from a series of
national health examinations and surveys conducted by NCHS from 1963–1994
and from supplemental data.
- The racial and ethnic distribution in the reference population
represents that of the U.S. population at the time each of the
National Health Examination Survey (NHES) and National Health and
Nutrition Examination Survey (NHANES) surveys were conducted.
- For the first time, nationally representative data were used to
construct the growth charts for infants — birth to 36 months of age.
- Nationally representative data were used to create the growth charts
for children and adolescents 2 to 20 years of age and were obtained
from 5 national survey data sets.
- The new reference represents the combined growth pattern of breast-
and formula-fed infants in the U.S. Approximately 50 percent of the
infants were reported to breastfeed with about 33 percent
breastfeeding for 3 months or longer.
