This page contains charts detailing PPP (Price per part) and PPM (Price per minifig) over the years. They are broken down into PPP and PPM for each category as well as each comparable category which is a term we use on Brick Insights to group categories that have similar part types. This page is a companion to this PPP article.
Since the charts contain a lot of data they can be a bit hard to read. You can toggle individual categories by clicking on them in the legend.
