Oil and gas. The Joint Organisations Data Initiative (JODI) coordinates the collection, standardization, and publication of oil and gas data from around the world; the 100+ countries that participate represent the vast majority of global production. The oil data goes back to 2002; the gas data goes back to 2009. Both datasets are updated monthly and track a range of subproducts (e.g., crude oil, diesel, jet fuel) and flows (e.g., imports, exports, production) for each country. Previously: Global and gas infrastructure (DIP 2018.06.06) and state-owned oil companies (DIP 2019.05.01).
Historical terrorist groups. Joshua Tschantret, a political science Ph.D. candidate at the University of Iowa, has compiled a dataset of 260+ terrorist groups formed between 1860 and 1969. For the purposes of the dataset, “terrorist groups are operationally defined as politically-motivated non-state actors using bombings or assassinations,” Tschantret writes in an introductory article (PDF). About one-third of the groups in the dataset operated in the US, Russia, or China; the rest are spread across dozens of other countries. Related: Additional documentation (PDF). Good to know: On Twitter, Tschantret explains why the Black Panthers are included. [h/t Carla Martinez Machain]
