From the summary:
This Americas Society/Council of the Americas report shows how immigration has helped revitalize New York City since the mid-1970s by making communities safer, increasing public revenue, and boosting the city’s population.

The data shows that immigration has reduced New York City’s crime rate by up to two-thirds over the last two decades, increased the city’s housing wealth by $188 billion since 1980, and significantly contributed to the city’s population growth, thereby helping the local economy to thrive and remain strong.
