Average comparability for each survey list by item classes and material classes. The proportion represented the average percentage of classes in other lists that the list plotted has. The x axis is the average comparability of the item classes, and the y axis is the average comparability of the material classes—an arrow points toward where we aim for survey comparability to go in the future. Marginal boxplots on the top and right axes show the boxplots for the x and y axis, respectively. Full list of comparability metrics for all survey lists is in the SI (Table S6)
