The National ABI 2008 - 2020
The trend in architectural design billings helps contruction related businesses forecast future trends. It's a common belief that if we don't study history, that we are doomed to repeat it. Thus, inside.lighting is providing a historical view of the ABI that shows how design billings were impacted by the Great Recession 2008 - 2010.
Like many ecomonic disclaimersstate, past performance may not be indicative of future results.
Interpreting the Architecture Billings Index:
The survey panel asks participating architectural firms whether billings increased, decreased or stayed the same in the month that just ended. According to the proportion of respondents choosing each option, a score is generated, which represents an index value for each month.
- An index score of 50 indicates no change in firm billings versus the previous month.
- A score above 50 indicates an increase in firm billings versus the previous month.
- A score below 50 indicates an decrease in firm billings versus the previous month.
- NOTE: Index numbers cited for the last three reported months are preliminary.
- The regional and sector categories are calculated as a 3-month moving average, whereas the national index, design contracts and inquiries are monthly numbers.
National Architecture Billings Index
The Architecture Billings Index (ABI) is a leading economic indicator for nonresidential construction activity, with a lead time of approximately 9–12 months. The index is derived from The American Institute of Architects (AIA) Work-on-the-Boards survey, which has gathered data on shifts in billings from architectural firm leaders for over 20 years.
