Cass Freight Index
A Measure of North American Freight Volumes
Since 1995, the Cass Freight Index™ has been a trusted measure of North American freight volumes and expenditures. Our monthly Cass Freight Index Report provides valuable insight into freight trends as they relate to other economic and supply chain indicators and the overall economy.
Data within the Index includes all domestic freight modes and is derived from nearly $21 billion in freight transactions processed by Cass annually on behalf of its client base of hundreds of large shippers. These companies represent a broad sampling of industries including consumer packaged goods, food, automotive, chemical, OEM, retail and heavy equipment. Annual freight volume per organization ranges from $1 million to over $1 billion. The diversity of shippers and aggregate volume provide a statistically valid representation of North American shipping activity.

How the Index Works
The Cass Freight Index uses January 1990 as its base month. The index is updated with monthly freight expenditures and shipment volumes from the entire Cass client base. Volumes represent the month in which transactions are processed by Cass, not necessarily the month when the corresponding shipments took place. The January 1990 base point is 1.00. The Index point for each subsequent month represents that month’s volume in relation to the January 1990 baseline.
Each month’s volumes are adjusted to provide an average 21-day work month. Adjustments also are made to compensate for business additions/deletions to the volume figures. These adjustments help normalize the data to provide a sound basis for ongoing monthly comparison.
