1/4 Data on COVID-19 testing is crucial, but definitions are messy, sources are hard to check, and figures change quickly.

We are trying to build a scalable database. We have so far time series data for 26 countries with thorough source descriptions here: ourworldindata.org/covid-testing 2/4 We have made a checklist on the key comparability and data quality issues to keep in mind when collecting and using this data. These are the questions that we try to answer when we compile the data for each country.

It’s not a straightforward question at all: Some factors may bias death counts up, others down.

New datasource on a very important question! The V-DEM project (Varieties of Democracy, @vdeminstitute) measures democratic institutions across the world, with long-run series going back to 1789
