        <p> The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides Federal grants to States for supplemental foods, health care referrals, and nutrition education for low-income pregnant, breastfeeding, and non-breastfeeding postpartum women, and to infants and children up to age five who are found to be at nutritional risk.</p>

        <p>The scatterplot compares the number of WIC Participants and Free and Reduced Lunch participants by state.</p>
