Influx of People: New York City

Based on the calculations detailed below, about five people moved into New York City each hour from U.S. states (other than NY) and overseas in 2017. Below is an overview of the findings and calculations.
  • New York City is made up of five boroughs, which are also counties. They are New York County, Kings County, Bronx County, Richmond County, and Queens County.
  • From 2013 through 2017, it is estimated that 60,551 people moved into New York County from a different state and 30,121 came in from abroad. The total of 90,672 immigrants divided by five years brings the number of people who moved to the county to about 18,134 people per year.
  • From 2013 through 2017, 29,309 people moved into Kings County from a different state and 24,640 came in from abroad. The total of 53,949 immigrants divided by five years brings the number of people who moved to the county to about 10,790 per year.
  • From 2013 through 2017, 10,263 people moved into Bronx County from a different state and 14,220 came in from abroad. The total of 24,483 immigrants divided by five years brings the number of people who moved to the county to about 4,897 per year.
  • From 2013 through 2017, 2,177 people moved into Richmond County from a different state and 1,708 came in from abroad. The total of 3,885 immigrants divided by five years brings the number of people who moved to the county to about 777 per year.
  • From 2013 through 2017, 17,950 people moved into Queens County from a different state and 24,808 came in from abroad. The total of 42,758 immigrants divided by five years brings the number of people who moved to the county to about 8,552 per year.
  • Therefore, the estimated average number of people who moved into New York City per year between 2013 to 2017 = 18,134 + 10,790 + 4,897 + 777 + 8,552 = 43,150.
  • Being that 2017 was a common year, and there are 8,760 hours in a common year, then the hourly influx of people to New York City in 2017 = 43,150/8,760 = 4.92579908676 = 5

RESEARCH STRATEGY

While most resources seem focused on the number of people that NYC loses each year due to outbound migration, our exhaustive research produced various resources that provided estimates of the number of people who move into the city. A report by NYC Planning provides the latest data but it does not breakdown the number of domestic immigrants by origin, therefore, it was not possible to determine how many were coming from out of state. Forbes provides an interactive map but it was last updated in 2012 and a report by StreetEasy based its estimates on 2011-2015 ACS Census data. Therefore, the research team decided to use the latest consistent data set available (2013-2017 census data) in our calculations. We summed up the number of people who migrated into each of the five NYC counties from other states and abroad then divided by five because the "flow estimates resemble the annual number of movers between counties for a 5-year period." The calculations have been detailed above. Kindly note that we have provided screenshots of the data in a Google Doc because the link to Census Bureau's interactive map does not provide the relevant information. However, the interactive map is easy to use and it would not be difficult to access the data.
