Accuracy and precision
Data is fairly inaccurate and imprecise, with the accuracy and precision getting worse the farther back in time we go, and also varying significantly across geographical regions. However, the database does not provide error bars or any other explicit quantification of uncertainty.
The working paper uses [[Steve Broadberry's classification of data sources]], listing four broad types of data sources in decreasing order of reliability, along with the color coding that should show up in the database.<ref name=maddison-project-2013-update/>{{rp|4}} Unfortunately, the color coding does was not seem to show up implemented in Mac's Numbers or in Google Sheetsthe dataset.<ref name=maddison-project-2013-data/>
