The ABI serves as a leading economic indicator that leads nonresidential construction activity by approximately 9-12 months. The survey panel asks participants whether their 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 represents no change in firm billings from the previous month, a score above 50 indicates an increase in firm billings from the previous month, and a score below 50 indicates a decline in firm billings from the previous month. *All graphs represent data from September 2020–September 2021.
