Viewing the city’s rent burden spatial distribution over the years one can identify the PUMAs that are at risk for displacement due to increasing rent burden. Also Figure 4 shows that the percentage difference between rent burden 2010 and 1990. The map shows northern brooklyn, northern east Queens, northern the Bronx, and Staten Island has higher rent burden growth than other NYC neighborhoods.

Overall, most of the neighborhoods have become more integrated in two decades, except top 6 median income level and Brooklyn Height. 5 out of 7 neighbors are in Manhattan and the others are located in Brooklyn. Fig.6 shows three maps of each year’s spatial distribution of the Income Integration level (entropy index).
