Introduction

This website is intended as a reference to track US regional trends in COVID-19 cases and deaths.

Before looking at the graphs below, please read this one HUGE caution:

THESE DATA ARE WRONG

By that, I mean that the data are not reality in the sense that most people want. They do not tell us the actual number of cases and deaths per day due to COVID-19. They are a super-dirty, extremely-noisy, very-wrong best attempts at measuring cases. They are most certainly underestimates of the true case load.

The graphs are best interpreted looking at the direction of the states’ long term trends and not as reliable reports of what is going on right now at this very moment. That being said, it is also amazing we have this caliber of data at all, even if there is inevitable noise. The people aggregating these numbers are doing an incredible job and have played an important role in managing the crisis!

Update 3/31/2020: All states are now up on the website and sorted by US Census Bureau. If you think your state is weirdly categorized, blame the Census Bureau. Who know Delaware is in the south.
The Midwest States
The Northeast States
The Southern States
The Western States

With that, I wish you happy and cautious data gazing!

Last notes:

• A refresher about log scales. On the y-axis you will sometimes see it in log10 scale. This makes it so that the space between 0-10, 10-100, 100-1000, and so forth are the same distance. This helps to visualize trends of things that happen explosively, like the exponential growth of a virus. I provide both an untransformed and log10 transformed scale below.

• The x-axis below should be interpreted as “days since the state reported its 10th case/death (depending on chart)”. This helps to show where each state is from a standard reference point in time and facilitates better comparisons of trends.

Worst Affected States

The Top 10

Here are reports for the top 10 states by reported number of cases. These are the states where COVID-19 seems to be most active.

Cumulative Cases per 100,000 People

These data are how many cases for every 100,000 people in the state. It helps to compare more populous states from less populous ones.
