Coronavirus Data Hub FAQ: What you should know about our COVID-19 dataset

Editor’s note: Since published, we’ve updated the data source to make sure everyone has uninterrupted access to the latest data. Learn more about the latest data source.

The 国家授权正规彩票 COVID-19 Data Hub contains resources to help you visualize and analyze the most recent data on the coronavirus outbreak. On the hub, we’ve created a jumpstart workbook, pre-loaded with COVID-19 case data, that anyone can download and use for their analysis. We want to make sure that you’re fully informed about the data you’ll be working with on the hub. Below, we’ve compiled answers to some key questions about the data. We know this situation is changing rapidly, so as the data and questions change, we will update our answers accordingly.

Where is the dashboard data coming from?

The data comes from the dataset maintained and updated by the Johns Hopkins University Center for Systems Science and Engineering. 国家授权正规彩票 cleans, reshapes, and makes this data ready for your analysis.

What range of dates does the data show?

The data captures case numbers for every day from January 23, 2020 to the present day.

How is the data sorted geographically?

Every country and region is represented in the data. For the following countries, data is provided at the province or state level: Australia, Canada, China, Denmark, France, Netherlands, United Kingdom, United States.

For the United States, data is also provided at the county level. We started displaying county-level data on March 26, and it is available from March 23 onward. Due to this relatively recent change in the level of detail provided, the “Difference” field has been appears as a null value—we are working through this issue.

I noticed that data on recovered cases is no longer available. Why is that?

On March 24, JHU stopped providing data on recovered cases due to a lack of confidence in the data. This means that we’re no longer able to differentiate between active and recovered cases in the total case data, so we have removed those values from the dataset. This is a permanent change.

I saw guidance on the COVID-19 Data Hub about “vizzing responsibly.” What does this mean and where can I learn more?

In making these data resources available to the public for analysis, we want to make sure we’re advocating best practices—from the perspective of data visualization, and from the perspective of public health. This also means advocating for the idea of “flattening the curve”—the spike in the number of cases. We believe that this should be the goal of data visualizations representing COVID-19, as that’s what’s needed right now from a public health perspective.
