I became interested in how President Trump’s immigration policies might affect the size of the foreign‑born population in the United States. To explore this question, I created a Python package called acs‑nativity that provides a simple interface for accessing and graphing nativity data from the American Community Survey (ACS).
After publishing the package, I built a companion app that lets users explore foreign‑born population trends for any location in the United States. The app supports the nation as a whole, all states, and counties and cities with populations of at least 65,000.
Together, these tools make it easy to analyze how the foreign‑born population has changed over time — and to track how those trends evolve as the Trump administration’s immigration enforcement efforts unfold.
