These are the project files used for analyzing census population estimates and IRS migration data for New York City and the New York Metro Area for the paper "New York's Population and Migration Trends for the 2010s" published in the Weissman Center for International Business Occasional Paper Series in Fall 2020.

Scripts for data processing and analysis are Python Jupyter Notebooks with Pandas stored in the scripts folder. Source and output data is saved in subfolders under this folder. Go to scripts/output/data to access summary migration and estimates data for NYC and the NYMA.

The data for this project comes from: Vintage 2019 census population estimates, IRS county to county migration data from 2011-12 to 2017-18, and the 2014-18 American Community Survey.
