This Technical Note outlines the COVID-19 matched dataset from the Young Lives cohorts in Peru created by the Young Lives team.  The matched dataset combines COVID-19 administrative data with the extensive longitudinal data set from the Young Lives study in Peru.  The authors document the steps taken to create a set of variables that measure the number of COVID-19 cases, deaths and vaccine doses applied in the districts where Young Lives participants reside, along with the duration of the lockdown periods they endured.  They collected administrative data and integrated it with the Young Lives datasets from Call 2 (August to October 2020), Call 3 (November to December 2020), Call 4 (August to September 2021) and Call 5 (November to December 2021).  This data matching process enables assessment of how the COVID-19 pandemic had an impact on participants development outcomes, including their health, well-being, and their education and work lives.
