Public Policy Adoption Index
What is a Public Policy Index? It’s a measure of how many public policies a country has adopted to control the pandemic. The higher the number, the more policies a country has adopted. Our index is based on an index created by Oxford University. We track several public policies intended to help control the pandemic. These policies include the closing of schools and non-essential businesses, and stay-at-home orders, among other policies. Measures are weighted based on the date when they were implemented, and on how long they’ve been in place.
Data for Brazil and Mexico come from the Observatory and reflect the average of a state or the federal district, weighted by the population of the state or the district. Data for the other countries come from the Oxford Government Response Tracker and are coded at varying levels.
Change in mobility; percentage change compared to usual mobility
Estimates based on Google data. These graphics show the change in population mobility in each country, compared to the usual mobility in the same time period (identified as the 0-baseline.) A decrease in mobility might also decrease the likelihood of community spread.
