Architecture Billings Index

The Architecture Billings Index (ABI) is a leading economic indicator that reflects the health of the construction and design industries in the United States. It measures the demand for architectural services by tracking billing amounts from firms. A higher ABI indicates more work and increased confidence in the construction sector, suggesting future growth, while a lower index signals a slowdown. Architects and industry professionals use the ABI to gauge trends, predict project timelines, and understand market conditions, which can ultimately impact economic development and employment within the sector.
