Abandoned children reshape child welfare systems in different countries—and the signals vary by where and how cases are reported. In China, tens of thousands of abandonments were reported across 2010–2012, alongside a striking gender imbalance: 98% are girls. In the U.S., maltreatment affects young children and fuels developmental risk, while foster care numbers in FY2020 show how many children entered and exited care. The page compares patterns across countries and then connects these findings to development impacts and permanency planning.
