Child Nutrition Statistics

With 30.2 billion in US federal child nutrition spending in FY 2022 but 46% of children under 5 globally missing a minimum acceptable diet, this page puts pressure on the gap between resources and outcomes while also tracking risk factors like 147.6 million children affected by child food insecurity worldwide in 2022. You will see the scale of feeding solutions too, from 12.2 million average daily School Breakfast participation in 2022 to WIC reaching 49.6 million people, alongside evidence on what improves health such as pooled effects that cut stunting risk by up to 24%.

Roughly 147.6 million children were estimated to be living with child food insecurity worldwide in 2022, even as obesity and overweight remain stubbornly high across countries. In the US alone, 2022 federal spending reached $30.2 billion for child nutrition programs, while 91.9% of National School Lunch Program schools met Offer versus Serve requirements in at least one reviewed week. Put together, these figures raise a sharper question than “are kids getting enough,” since the data point to very different gaps in diet quality, risk, and outcomes that policy decisions try to close.
