Thomas Brambor, Agustín Goenaga, Johannes Lindvall and Jan Teorell created The Information Capacity Dataset for their article "The Lay of the Land: Information Capacity and the Modern State". The Information Capacity Dataset offers numerical data on five institutions and policies that modern states use to collect information about their populations and territories: (1) the regular implementation of a reliable census, (2) the regular release of statistical yearbooks, the operation of (3) civil and (4) population registers, and (5) the establishment of a government agency tasked with processing statistical information. The dataset also includes an overall index of “information capacity” for 85 polities from 1750 to 2015.
