aAIs for toddlers ages 1–3 y in the United States (IOM, 2002a). No weighting was done for this group.

bBased on U.S. Census Bureau estimates of the general population of the United States in 2005 ages 4 y and above (Population Projections Program, 2000).

cBased on U.S. Census Bureau estimates of the population of pregnant women in the United States in 2001 (Population Projections Program, 2000).

dIn the absence of specific data on the ages of lactating women, these values are based on National Vital Statistics System estimates of the population of pregnant women in the United States in 2001 (Ventura et al., 2003).
