New York City - In-migration
To remove the interstate migration from the provided dataset (i.e. people who move to Bronx County from all other NY state counties), re-calculate total, and validate these in-migration estimates through another source (either another US census dataset or external source).
- After excluding the interstate migration data and recalculating the totals, the latest dataset has been provided in "Updated — New York City (5 counties)" tab of the shared spreadsheet.
NYC Total Inflow — 2013-2017
- Updated in-migration data after excluding the interstate migration is as follows:
- A total of 24,483 people moved to Bronx County, New York from other US states and abroad.
- 53,949 people moved to Kings County from other US states and abroad.
- 90,672 people moved to New York County from other US states and abroad.
- 42,758 people moved to Queens County from other US states and abroad.
- 3,885 people moved to Richmond County from other US states and abroad.
- Total in-migration in all five NYC counties = 24,483 + 53,949 + 90,672 + 42,758 + 3,885 = 215,747
- Hence, a total of 215,747 people moved to NYC from other US states and abroad.
- Out of the 215,747 people, 120,250 moved to NYC from other US States.
- This indicates that only 95,497 people moved to NYC from other countries during 2013-2017.
- To ensure that our in-migration calculations are correct, we compared these calculations with the New York tab of the "inflow dataset" for "County-to-County Migration Flows" provided by the US Census Bureau.
- This inflow-only dataset can be found in this shared spreadsheet. We used estimates for "Movers from Different States" and "Movers from Abroad" to find the in-migration to the five counties of NYC.
- The in-migration numbers in both datasets are the same.
- We also tried to verify these numbers from external sources but found that data for these exact years (2013-2017) is hard to come by and several news reports focus more on net migration or out-migration statistics. We could not review any other external sources including the IRS migration data due to shortage of time.
Proposed next steps:
You need to be the project owner to select a next step.
We recommend research to find the in-migration data for the five NYC counties using external sources. However, if statistics for comparable years i.e., 2013-17 are not available, we will provide estimates for other available years.
Alternatively, we can just focus on finding the most recent domestic and international in-migration statistics for NYC published in news and media resources.
