OVERVIEW

Margins are included in all IMPLAN models and databases. Margins allow for purchases from Retail and Wholesale industries to be appropriately allocated among the retailer, wholesaler, transporters, and producer of the good in question, thereby correctly attributing the appropriate portion of the good’s sale price among all actors involved in bringing the good to the customer. Note, however, that margins in IMPLAN are not regionally specific. This article briefly discusses the margin data sources. Read more about the importance of Margins for analysis. 

MARGIN DATA SOURCES

Commodity margins are derived from the Bureau of Economic Analysis’ (BEA) Benchmark Input-Output tables. These Margins are updated annually and come from the Census Bureau’s Annual Retail Trade Survey and Annual Report for Wholesale Trade.
