Percentage* of Children and Adolescents Aged 4–17 Years with Serious Emotional or Behavioral Difficulties,†

"During 2011–2014 the percentage of children with serious emotional or behavioral difficulties was about twice as high among children living in poor families (<100% of the poverty threshold) compared with children living in the most affluent families (≥400% of the poverty threshold) (7.7% versus 3.8%). This pattern was found for both boys (9.9% versus 4.8% ) and girls (5.6% versus 2.8%). At each poverty status level a higher percentage of boys than girls had serious emotional or behavioral difficulties."
