The good news is that New York City already has many of the building blocks for a more integrated early education system in place. But it will take considerable problem-solving and intentional work—from policymakers and providers—to capitalize on existing opportunities for integration as well as open additional opportunities. This report attempts to give direction for some of that work, beginning with a discussion of why diversity in early education matters in the first place, followed by a summary of what we know about the demographics of early childhood education nationally. The subsequent sections give an overview of the early childhood system in New York City, covering children from birth up to age five; discuss the opportunities and challenges that the system presents for integration; and offer broad policy recommendations for the steps needed to provide more of the youngest New Yorkers with access to integrated learning environments.
