Technology Adoption

Cross-country Historical Adoption of Technology (CHAT)

Data contains information on the adoption of over 100 technologies in more than 150 countries since 1800. Described is technology usage primarily based on per capita measures and divide technologies into the two broad categories of production and consumption.
