How to read these charts: Each panel shows the index level over the past 5 years and the 12-month percent change in the most recent period. For the PPI measures, a rising index means producers are receiving higher prices, which is a proxy for cost increases your projects could face. Rising costs are shown in red, falling costs in green, and mostly flat costs in gray. Data are refreshed each month.
