1. The document discusses research showing that investments in early childhood education can provide high economic returns by improving educational and life outcomes, reducing social problems, and allowing parents to work.
2. Studies like the Perry Preschool program and Abecedarian program found that early childhood interventions led to increased education levels, higher earnings, and less criminal behavior, with estimated returns of $16 or $4 for every $1 invested.
3. Factors like adverse childhood experiences, limited vocabulary exposure, and lack of quality early education can negatively impact brain development and create barriers to social mobility, highlighting the importance of interventions for at-risk youth.

Differences in development appear very early -- in this instance, differences in vocabulary growth between children in low socio-economic households and high socio-economic households begin to appear as early as 18 months. And as the children grow toward school age, and enter school, the differences only get larger in the absence of intervention.
And it’s not just cognitive development that is affected by early experiences--it’s also social-emotional behaviors and physical health. This study investigated adults with a history of Adverse Childhood Experiences in early childhood to determine whether these experiences increase the odds that they would experience alcoholism, drug abuse, and a range of unhealthy behaviors later in life. Perhaps not unexpectedly, all of these behaviors increased dramatically in adults who had higher numbers and prevalence of Adverse Childhood Experiences in their early years. But this graph shows that these experiences also lead to dramatically increased odds of having a range of physical health problems as adults -- in this case, cardiovascular disease. And these trends also appeared for diabetes, hypertension, stroke, obesity, and cancer.
