The March 2020 global poverty update added more than 200 new surveys to PovcalNet,
bringing the total number of surveys to more than 1,900. New poverty estimates for the reference year 2018 are now included for some regions, and the previously published global and regional estimates from 1981 to 2015 have been revised, reflecting data revisions and the availability of new data. More details on the revisions can be found in Atamanov et al. (2020).
