The ASID Interior Design Billings Index is a snapshot of the health of the interior design industry.
It is produced by the ASID Research department, under the leadership of ASID Vice President of Research and Knowledge Management David Krantz in partnership with Jack Kleinhenz, Ph.D., and Russ Smith, Ph.D., both of Kleinhenz & Associates. The index, which was begun in November 2010, is a diffusion index compiled from a monthly ASID survey of 300 geographically diverse firms that primarily offer interior design services or offer interior design services as part of architectural, engineering, and other related practices. Resulting perspectives on current and future business conditions for the interior design industry are helpful indicators of changes in the direction of economic activity. The ASID indices are centered on a score of 50 (above 50 indicates expansion and below 50 contraction).
