Relying on three new indicators of the information capacity of states, this paper provides new evidence on the ability of states to collect and process information about the territories and populations that they govern. The three indicators are (a) the availability of a reliable census, (b) the establishment of a permanent government agency tasked with processing statistical information about the territory and the population, and (c) the regular release of statistical yearbooks. We find, as expected, that there has been a secular increase in information capacity over time. We also investigate salient differences among countries from the early 1800s onward.
