This Etla brief introduces a method for comparing the maturity of national data economies using a composite indicator. We assess the data economy from three perspectives: the prerequisites set by the public sector, the utilization of data, and the innovation impacts within the data economy. Combined, these three sub-indicators form the Databarometer. The chosen metrics draw from publicly available data sources and cover elements such as ICT expertise, the use of artificial intelligence technologies, and data driven startups. The various indicators are integrated into a single composite indicator using the Digibarometer calculation framework developed at ETLA. Both the framework and the underlying data are openly available and well-documented, ensuring that the calculations can be easily replicated.
