Install miniconda, then in the command line, run

conda create -n covid-county
conda activate covid-county
conda install pandas ipython matplotlib tabulate

(Let me know if you want pure-Python no-Conda instructions via venv.)

I've already downloaded countypres_2000-2020.csv from https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/VOQCHQ but you can download it again to ensure I haven't committed bad data.

2020 data is missing counts for District of Columbia (FIPS 11001)? Party split taken from 2016 election.

From https://www.census.gov/programs-surveys/popest/technical-documentation/research/evaluation-estimates/2020-evaluation-estimates/2010s-counties-total.html I downloaded co-est2020.csv from the "Annual Resident Population Estimates for States and Counties: April 1, 2010 to July 1, 2019; April 1, 2020; and July 1, 2020 (CO-EST2020)" link. It's committed in this repo but you can download it yourself too.

Install Git and run this in this directory: git clone --depth 1 https://github.com/nytimes/covid-19-data.git (it might take a while)

Note five boroughs of NYC are combined into a single "county".

Fix follows the recommendation per upstream issue 105.
