@hackingdata @KrisKennedy You can see our notes on each number, too.

March 15, 2020, 1:35 PM PDT

By known positive tests, the 10 states with the highest per capita number of cases are: Washington New York Colorado Massachusetts Louisiana Rhode Island New Jersey South Dakota New Hampshire Georgia

March 18, 2020, 2:28 PM PDT

Among individual states, two stand out for different reasons. First, New Jersey's case total jumped from 267 to 427. Unfortunately, they only report total tests by their own public health lab, so we don't know the true denominator for the positives. https://t.co/NGrSCgFldX

March 19, 2020, 10:56 PM PDT

@GunaRockYa Do you think it's possible we'll see something like this out of New Jersey? https://t.co/fCH0Sk3mxR

Big transparency win and keeps people from thinking the positive rate for testing is too high! -@alexismadrigal

March 21, 2020, 2:18 PM PDT

New York accelerated past Washington in per capita positive tests. Here’s the top 10:

New York Washington New Jersey Louisiana DC Michigan Massachusetts Colorado Rhode Island Illinois

March 22, 2020, 2:25 PM PDT

New York continues to have the highest positive tests per capita, an indication of both the intensity of testing there and the severity of the outbreak. Here’s the top 10:

New York Washington New Jersey Louisiana DC Michigan Illinois Vermont Colorado Rhode Island

March 24, 2020, 1:59 PM PDT

New Jersey released new total test numbers today, too. The confirmed cases have grown rapidly as testing ramps up in the NY metro area. https://t.co/PARqhvwpSo

March 25, 2020, 2:20 PM PDT

Over the past two days, it is worth noting that two large states have begun reporting more complete testing data. NJ yesterday and OH today both moved the numbers.

CA remains a major question mark. We hope to see movement there later today.

WA is not yet reporting outcomes.

April 2, 2020, 3:27 PM PDT

Michigan continues to be a real trouble spot and now has the third highest number of confirmed cases (after NY and NJ), crossing 10,000 total today.

(We don't know nearly enough about their testing regime in the state, either.) https://t.co/5Vf1ymWOMH

April 5, 2020, 2:36 PM PDT

On Michigan. The state has the third-most confirmed cases and deaths (after NY, then NJ). We had not been including their negative test number because the state said it represented "specimens" not people.

April 6, 2020, 7:52 AM PDT

@JPVMan @Ian_Myers @GovMurphy Also, the number of hospitalizations went up by 1000 the next day. Could be NJ is a day or two behind NY. So many confounding factors.

April 6, 2020, 3:15 PM PDT

The nation passed 10,000 deaths today.

New York stands at 4,758 deaths. New Jersey passed 1,000.

16 states have lost more than 100 people to COVID-19.

April 6, 2020, 5:50 PM PDT

As of today, 8 states are reporting racial demographics for COVID cases: CT, IL, MI, MN, NC, NJ, SC, VA

And 5 states are reporting racial demographics for COVID deaths: CT, IL, LA, MN, NC

April 7, 2020, 3:23 PM PDT

One thing to note about hospitalization data: New Jersey, Illinois, and California are all including different sets of people in their numbers. We are reporting the lower numbers where they are available (as in CA, which breaks out confirmed and suspected COVID-19 cases).

April 8, 2020, 9:09 AM PDT

@vscooper @CCgirt I agree. NJ is going to see some very scary situations. --@alexismadrigal

April 11, 2020, 2:24 PM PDT

The death toll continues to be concentrated in New York and New Jersey, although Michigan, Illinois, and Pennsylvania continue to see substantial numbers of deaths each day. https://t.co/GbJ5RNM0mc

April 12, 2020, 2:23 PM PDT

Outside the NY-centric outbreak (NY, NJ, CT), Michigan has the most severe outbreak. https://t.co/P3hqp3Hd9B

April 30, 2020, 1:59 PM PDT

Deaths stayed above 2,000 today. New Jersey alone reported 460 deaths today. https://t.co/Fcj7uquV2k

May 2, 2020, 2:40 PM PDT

9 states reported over 50 deaths:

California: 98 Florida: 74 Illinois: 102 Indiana: 54 Massachusetts: 130 Michigan: 154 New Jersey: 204 New York: 299 Pennsylvania: 64

May 4, 2020, 3:08 PM PDT

One reason to expect that the death number will rise tomorrow would be to look at some key states—NJ, CA, MI, MA—all seem to show the same kind of reporting dip. https://t.co/m5TT3QWQfY

May 8, 2020, 2:18 PM PDT

Cases continued their slight drift downward, but it's important to remember that outside NY-NJ-CT, cases are not falling. https://t.co/LB17L585rx

May 9, 2020, 2:17 PM PDT

And an important reminder: the story is very different in different regions of the country. Outside NY-NJ-CT, cases are not really declining. https://t.co/LCsljoCpXK

May 11, 2020, 2:46 PM PDT

Our daily update is published. We’ve now tracked 9.4 million tests, up 395k from yesterday, a new high with a major caveat: NJ dumped a big backlog, it seems.

Note that we can only track tests that a state reports.

For details, see: https://t.co/PZrmH4bl5Y https://t.co/3gDkpXkH6o

May 11, 2020, 2:48 PM PDT

New Jersey appears to have taken the road that California did recently, moving away from reporting "people tested" and to "tests completed." But we're still trying to get confirmation on this.

As you can see, today is a bit of an outlier. https://t.co/2E9fh6WSuI

May 29, 2020, 3:25 PM PDT

States reported 1,186 deaths. Only New Jersey reported more than 100.

The 7-day average remained under 1,000. https://t.co/XL5uqsOUBf

June 2, 2020, 2:56 PM PDT

2/2

Missouri Nevada New Jersey New York North Carolina Ohio Pennsylvania South Carolina Tennessee Wisconsin

June 7, 2020, 3:35 PM PDT

Only 20k new cases were reported today. 24 states reported more than 300 new cases today.

New York and New Jersey tested more than 102k people combined, and only got ~1k positives.

On the other end of the spectrum, Arizona tested ~10k people and confirmed 1,438 new cases. https://t.co/q7b8gj50V2

June 8, 2020, 3:14 PM PDT

States reported 640 deaths. The 7-day average ticked up a little.

Deaths in the NY, NJ, and CT have plummeted. They've also fallen elsewhere, but much more slowly. https://t.co/9DYyuzcrLY

June 22, 2020, 2:59 PM PDT

Take out just three states from the data—NY, NJ, and CT—and a different story emerges.

The positive rate outside that area never reached as high, nor did it ever get as low. And it began climbing over the last week. https://t.co/23x5Yse3wV

June 25, 2020, 3:08 PM PDT

There are important caveats in today's data:

New Jersey reported 1800+ probable deaths from previous days. That number is in our API, but we will exclude it from charts here.

We think we'll be able to get historical data from NJ in order to properly assign those deaths.

June 25, 2020, 3:08 PM PDT

  1. Wisconsin reported 2.8k probable cases today from previous days. They are also in the API, but excluded from the charts presented here.

As with NJ, we hope to be able to properly assign those probable cases to the right dates, too, with the state's help.

July 8, 2020, 4:48 PM PDT

This is the same pattern we saw for cases and hospitalizations over the last couple months. Compare Arizona, New Jersey, New York, and Texas. https://t.co/Uz6d2aQ9LU

July 8, 2020, 5:05 PM PDT

New Jersey has been adding probable deaths to its backlog. We put them in our raw data, but have kept it out of these charts, so that it’s easier to see the current trends. We’re still hoping to get more data from the state so that we can properly backfill those deaths. https://t.co/DDhlQT8tcA

July 25, 2020, 3:49 PM PDT

It’s the weekend, so as usual, the data is less complete than on weekdays. Michigan didn’t update today bc of tech problems; New Jersey only posted positive results, no totals or negatives.

July 30, 2020, 4:03 PM PDT

California is now #3 in the United States for total COVID-19 deaths, behind New York and New Jersey. We hope that declining case counts in CA will be reflected in falling deaths within the next 2-3 weeks. https://t.co/iGGokUAjGB

July 31, 2020, 3:46 PM PDT

The 7-day rolling average of deaths for Texas and Florida has now surpassed some early hotspots like Michigan and Massachusetts.

The trajectory looks more like harder hit states like New Jersey. https://t.co/D49edXZKXT

August 4, 2020, 3:29 PM PDT

Data on current hospitalizations remains iffy. Today we saw hospitalization numbers in ID and NJ drop by ~50%, which seems unlikely to reflect reality. Some states with rising cases have dropping hosp. figures.

Last week's post is likely still relevant: https://t.co/wLbFSPAfZW

August 7, 2020, 3:52 PM PDT

We were able to backfill all New Jersey deaths, redistributing the previous large June 25 spike of probable deaths to the correct days. Thank you to @govmurphy and @NJDeptofHealth for publishing the data we needed to improve the dataset. https://t.co/2kKeoGhUi8

November 14, 2020, 3:20 PM PST

38 states reported over 1k cases. CO, IN, KY, MD, MN, MO, MT, ND, NH, NJ, NV, PA, WV, and UT all set records for detected cases. (5 states did not report cases.) https://t.co/3Gi0ieFO3i

November 15, 2020, 5:00 PM PST

New Jersey reported 128,343 tests today—much higher than a normal day. We haven’t found an explanation, but we’ll keep an eye out.

November 21, 2020, 4:44 PM PST

40 states reported over 1,000 cases today. And four didn't report. New Jersey, California, Mississippi, Idaho, and Oregon reported record numbers of cases. https://t.co/q23xwQ3BW7

December 1, 2020, 4:35 PM PST

A handful of states reported data for more than one day today, a result of data disruptions caused by the Thanksgiving holiday. On the other hand, CO, NJ, TX, WA, and WY only published partial updates today.

December 3, 2020, 4:54 PM PST

Zooming into the state level, more than 10 states broke case records today: AK, AR, AZ, DE, IN, MA, ME, NJ, PA, RI, and VT. Note: AZ had a higher count on Dec. 1, but it was a data backlog. https://t.co/ao6T6EQxiH

January 8, 2021, 4:58 PM PST

NJ reported nearly 20K probable COVID-19 cases and CA reported over 50K cases. Both states greatly influenced the large uptick in today's total cases.

January 9, 2021, 4:58 PM PST

The past week had the most reported cases, average hospitalizations, and deaths of any week during the pandemic.

We are still seeing post-holiday instability in the data - NJ reduced their probable cases number by more than 10k since yesterday. https://t.co/0Ab7viJ7Wr
