COVID-19 Data Center

Open access to high-quality popular data sources of general interest through our Rich Data Services API and web applications to support research and decision making.


Rapid access to high quality COVID-19 and related contextual data is critical for policymakers, researchers, the media, and the public at large, to understand and effectively respond to emerging evidence. Such data is, however, not particularly easy to find and access, and is rarely in pristine or ready-for-use state. More importantly, it is rarely published in machine friendly formats or "as a service", locking it away from the information systems, data scientists, developers, or machine learning environments. These issues result in significant data wrangling, unreliable modeling, and misinterpretation while dramatically slowing down our capacity to react.

Given the critical needs for timely access to high quality COVID-19 data, we strongly believe our Rich Data Services platform, combined with our strong expertise in data and metadata management, can make a significant difference in addressing this global crisis, both in the short and long term.

Through the delivery of free high quality COVID data as a service, this project aims at:

  • Offering data scientists, developers, and other users a flexible platform for the discovery, extraction, and online or offline analysis of data
  • Granting immediate data access to computer applications or web sites, enabling rapid retrieval, analysis, visualization, machine learning, or other purposes.
  • Addressing quality issues by delivering curated data in open formats, ready for immediate use, allowing the focus to be on the research, and reducing wrangling and other time-consuming tasks
  • Facilitating harmonization and data linking through the use of standard classifications and common variable naming conventions
  • Promoting the use of open data, domain standards, and related best practices
  • Making curated data and tools developed for this project available in a public repository

Getting Started

RDS Explorer

Explore the Data

Use the RDS Explorer to browse the data, consult the codebook, create custom extracts by filtering records and selecting variables, or produce personalized open data packages for download.

The tool can also be used by developers and data scientists to generate API calls or source code for instantly reading the data into analytical tools, creating visualizations, and for other purposes.

Johns Hopkins Reports, Fairfax County, VA
COVID Tracking Project for New York State
Ohio Cases for Males aged 50 and over
Hospitalized community exposure cases in Canada
Select your data and explore!

Aggregate the Data

Use the RDS Tabulation Engine to aggregate data across various dimensions to rapidly create analytical tables. Start from scratch, or select from the following examples:

Confirmed Cases in 2020 for CA, CN, ES, IT, US
Tests per day in New York and Kings counties
Canada Labour Force Trends in 2020
Select your data and tabulate!
RDS Tabulation Engine

The tool can also be used by developers and data scientists to generate API calls or source code for instantly reading the data into analytical tools, creating visualizations, and for other purposes.


For Developers

Resources and examples to get you underway. Visit the RDS web site developer section for additional information.

Data Sources

We are in the initial stages of this project and are initially focusing on popular or quality pilot datasets. We are currently providing access to the following:

  • Case counts based on the Johns Hopkins daily report organized by Country, U.S. States, and U.S. County
  • U.S State level case and tests data from the COVID Tracking Project
  • Datasets collected directly from selected U.S. State agencies (New York, Ohio, Tennessee)
  • Case data from the Government of Canada and Statistics Canada
  • Canada Public Use Microdata files for the just-released Impacts on COVID-19 Survey the Labour Force Survey (Jan 2018 - Apr 2020), and other relevant datasets

See our public COVID-19 GitHub project for more information on these resources, along with source data and tools we are using to curate and publish in our catalog. We have identified several other potential sources, and anticipate for our collection to rapidly grow over time. We naturally welcome your suggestions.

Note that the nature of the data drives how the RDS API and applications should be used. Make sure you understand the data before jumping into the applications or analysis. Traditional survey data is naturally easy to browse or tabulate, but may require the use of statistical weights. Time series data, commonly used by many of the COVID-19 datasets, must always include a time dimension in their analysis. Be a responsible user!

Data Sources

Users & Researchers

COVID-19 data can be accessed through the following web applications, built for your convenience on top of the RDS API, and offering a browser-based user interface:

  • The RDS Explorer, which allows you to browse record level data, create subsets, and download in various open formats for offline analysis.
  • The RDS Tabulation Engine: for quickly creating analytical tables or data extracts for visualizations.

Developers & Data Scientist

If you are an application/web developer, scientist interested in data as a service, or into machine learning, RDS has you covered. No longer shall you need to spend hours data wrangling or coping with proprietary systems.

RDS is a REST based Application Program Interface (API) that can be used to concurrently query data and metadata from your favorite package or environment, to support web portals, visualizations, applications, analysis, or download.

Data Publishers

RDS is, amongst other things, a modern data publication solution. For this particular project, we act as the data broker by collecting, curating, and publishing the data ourselves. Contact us if you do have data that you feel would be a good addition to our COVID-19 project data collection.

Our RDS platform is also available to early adopters, visit our Rich Data Services website for more information.

If you need assistance getting started or have any questions, consult our knowledge base or simply open a free helpdesk request for assistance.

What's Next

RDS Explorer, RDS TabEngine, or above examples, are just a few of the many potential uses of the RDS API. Building your own applications or visualizations, accessing the data and metadata from your favorite analytical tools, integrating with your web portal, or enabling machine learning is where the power of the platform lies. So unleash your creativity, skills, and passion and use RDS in your own way.

Our project objectives are to help deepen the understanding of COVID-19, support better research, and foster evidence-based decision making. We also hope to encourage the adoption of best practices for the publication of data. Should you need assistance, you can:

How To Help

This initiative is primarily supported through internal resources, which can be challenging for a small company. We welcome any kind of support you may be able to provide to help us focus on free public data services. This includes financial support, in-kind contributions, and domain expertise. At this time, we are particularly looking for:

  • Direct sponsorship or donations
  • Funding opportunities, and assistance preparing or submitting proposals
  • Amazon Web Services credits to operate the infrastructure (or engineering support)
  • Suggestions or feedback on how we can improve the data offering, data quality, or our platform in general
  • Spreading the word about the data center and RDS

About Rich Data Services

The web applications and services (API) are powered by our Rich Data Services (RDS) platform, empowering both information systems and users by concurrently delivering data and metadata as a service in formats engineered for immediate use. As a developer or data scientist, you can directly query the data through the RDS API and open source libraries to build your own solution or for analytical purposes. Casual users and traditional researchers can leverage our browser-based application to explore, tabulate, or download data for offline analysis.
