Cardboard Box Index

Cardboard Box Index

A measure of the production of cardboard boxes. The cardboard box index is used to gauge the production of consumer goods. Because the vast majority of non-durable goods are shipped in cardboard boxes, higher demand for them usually equates to higher production of these goods. As such, the cardboard box index is considered a fairly reliable indicator of industrial production.
