Baltimore Sun analysis

By Christine Zhang

The Baltimore Sun conducted an analysis of county-level population estimates by age, sex and race/ethnicity analysis for a story published June 19, 2019 titled "Baltimore's white population swells with millennials, resembling D.C., Brooklyn".

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. Note that these files are compressed as input/ and output/ and will need to be unzipped prior to analysis.
