25:null 26:["$","title",null,{"children":"NYC & LI 2015 Child Opportunity Index | Duy Nguyen | Observable"}] 2b:T437,md`From diveresitydatakids.org, the Child Opportunity Index (COI) 2.0 measures conditions crucial to child development in over 72,000 census tracts around the U.S. For each tract, 29 indicators across three major domains — Education, Health & Environment, Social & Economic — are used to calculate a final score from 0 to 100. This post examines the final scores of tracts across seven counties in New York City (five) and Long Island (two) — and scores for each domain. All scores are *nationally* standardized. This means that if a tract has a score of 90, its level of opportunity is considered to be higher than 89 percent of (recorded) tracts across the U.S. In addition, scores reflect opportunity levels in *2015*. *A lot may have changed since then.* Census tracts comply to 2010 census information.

Harlem, like The Bronx, is historically and predominantly a black neighborhood. The Lower East Side features a cluster of low-income housing projects. The Upper East Side and Tribeca are among Manhattan's priciest neighborhoods. Polarization is also happening in Brooklyn. Heavily gentrified neighborhoods such as Brooklyn Heights and Park Slope have very high levels of opportunity, but as we move further away from Manhattan — also into black neighborhoods — scores fall drastically.
