1Data from the U.S. territories are excluded from the national breastfeeding estimates to be consistent with the analytical methods for the establishment of Healthy People 2030 targets on breastfeeding.

2Exclusive breastfeeding is defined as ONLY breast milk — NO solids, no water, and no other liquids.

3Poverty Income Ratio = Ratio of self-reported family income to the federal poverty threshold value depending on the number of people in the household.

4Unmarried includes never married, widowed, separated, divorced and living with partners.

5Metropolitan area is defined by the Census Bureau.

6WIC = Special Supplemental Nutrition Program for Women, Infants, and Children. Individuals who did not provide information on WIC status were excluded from analysis of this variable.

NA = Estimate not available because the 95% CI was mostly greater than 10 in these subgroups.
