COVID-19 cases, deaths, and tests by age and sex

This project is currently in development, stay tuned for documentation. You can get preliminary output in 5 and 10-year age groups in the /Data folder. This contains columns for Cases, Deaths, and Tests. There may be more populations availale in the unharmonized input database (inputDB.csv), because some are awaiting corrections or additional inputs .

Getting started

A short guide to reading the data into R can be found here. We will add other basic scripts for common data operations, and we will add some Stata examples too.

Data availability

You can get the most up-to-date data at the OSF site that we mirror to:

Here's an overview of global coverage as of now. A country marked as forthcoming means we've identified a source, but that collection is pending for one reason or another. Are you from one of the countries not yet in the collection and want to pitch in? Please reach out, if so by emailing us as coverage-db < at > coverage map

A detailed dashboard of data availability can be found here.

Data processing steps

A draft Method Protocol is available here

A dash overview of which steps are applied to each country-region-date subset of data can be found here.

This does not yet give an overview of age-group harmonization performed, but we'll add this soon. Further details will be spelled out in a methods protocol, presently in preparation.


Source documentation is presently being gathered and standardized, and we will find a slick way of displaying it when it's further along. All data results are provisional and may change if we decide to change particular sources, or if we change our minds about how to split age groups, etc. So please always use the most up-to-date version.


A basic data source dashboard is available here.


Most populations in the database contain multiple time snapshots, and all are continually monitored for new data releases. All statistics reported here are cumulative.

If you know of sources for other populations, please either email, Tweet, or leave an Issue in this repository, and we'll look into it. If you would like to assist this project in gathering data, or other tasks, please let us know and I'm sure we can find a task!
