From January to May, 2015 the CIDI commissioned a Capstone team from Columbia University's School of International and Public Affairs (SIPA) to create a place-based index of socio-economic well-being in NYC communities. The use of an index, a composite measure with weighted domains and indicators, facilitates the synthesis of data from disparate disciplines in order to paint a more holistic picture of quality of life and track differences between and among populations over time. Well-being, by definition, is a subjective perception of one's quality of life. In a city such as New York, with its wealth of diversity and preferences, community well-being can be difficult to capture; nonetheless, certain indicators do indeed correlate with a community's state of well-being. This research attempts to integrate data on a range of indicators that approximate the well-being of New Yorkers within the City's neighborhoods.
