The Architecture Billings Index (ABI) is derived from the monthly Work-on-the-Boards survey conducted by the American Institute of Architects (AIA) Economics Market Research Group. ABI is a leading economic indicator that leads nonresidential construction activity by approximately 9-12 months. Participants in the monthly Work-on-the-Boards survey panel are asked whether their billings increased, decreased, or stayed the same as the preceding month. According to the proportion of respondents choosing each option, a score is generated, which represents an index value for each month.
