Interpretation
Demographics Interpretation
It's a damning paradox that while overall numbers have slightly improved, the system remains a starkly overused last resort for America's children, disproportionately funneling them, especially the youngest and Black youth, through a cycle of trauma where neglect is the most common reason for entry and "home" is a temporary, often unstable, concept for an average of nearly two years.
