Baltimore Sun analysis

By Christine Zhang

The Baltimore Sun conducted an analysis of county-level population estimates for the state of Maryland — with a focus on the city of Baltimore — for a story published April 18, 2019 titled "Baltimore sees biggest population loss in single year since 2001, census estimates show" (print headline: "People continue to leave Baltimore").

The Sun's findings and analysis are available in the "analysis" notebook in this repository: 02_analysis.ipynb. The pre-processing code is in the "processing" notebook in this repository: 01_processing.ipynb.

The raw datasets are saved in the input folder. The cleaned files are saved in the output folder.
