Recognizing their critical role, the Best-Performing Cities (BPC) index evaluates the relative economic performance of 403 metropolitan areas, providing valuable insights into the strengths and vulnerabilities of these economic powerhouses.The BPC index utilizes 13 key metrics, combining labor market conditions, high-tech industry growth, and access to economic opportunities.
