A study has identified 15 neighborhoods in New York City that can be categorized as gentrifying, DNAinfo reports. The study was published by the NYU Furman Center as part of its State of New York City's Housing & Neighborhoods - 2015 Report (PDF!). It qualifies gentrifying neighborhoods as those that were relatively low-income in the 1990s, but have seen a dramatic increase in median rent in the last 20 years.

Unsurprisingly, Williamsburg is right at the top of that list. The neighborhood saw the average rent increase by 78.7 percent between 1990 and 2010-2014. Central Harlem followed in second place with a 53.2 percent increase in the same time period.

Of the 55 neighborhoods, the study analyzed, 15 were categorized as gentrifying, seven as non-gentrifying, and the rest as high-income. What does that mean? Non-gentrifying neighborhoods were those neighborhoods that were low-income in the 1990s and haven't seen a dramatic change in the last 20 years, and high-income neighborhoods are those that were already in the top 60 percent of the income bracket back in the 1990s.

The study revealed some other interesting facts about these gentrifying neighborhoods. For instance these neighborhoods saw a greater increase in educated residents and single-family households compared to the rest of the city. These neighborhoods also saw an increase in white population and a decrease in black population, with statistics measured up to 2014.

The NYU Law School will livestream an event focused on these findings between 4 p.m. - 6 p.m. today.
