What is it about?

As a reaction to the spread of the new coronavirus in early 2020, countries across the world introduced restrictions to human movement. We collected restrictions in a systematic way and present a new data set: Which country had what kind of restriction when (and what exemptions)?

Why is it important?

The restriction of human movement in the fight against the new coronavirus affects people's fundamental rights. We need to know whether these restrictions are effective, how different restrictions gain popularity, but also how restrictions are lifted again. With this systematic data collection, we provide other researchers with a tool to better understand the consequences of Covid-19 in the wider sense.
