City Business Profiles
Houston, TX
Houston is the world's energy capital with a COL index of 96, below the national average despite its massive scale — a combination that makes it highly attractive for operations.
oil & gas, healthcare (Texas Medical Center), port & logistics
Houston's lack of zoning creates unique commercial real estate dynamics; neighborhood character can shift dramatically within a few blocks, affecting foot traffic and customer demographics.
San Diego, CA
San Diego has a COL index of 146, driven by high housing costs, with California's full employer obligation suite — SUTA, SDI, and high workers' comp — adding to the burden.
defense & naval, biotechnology, telecommunications
San Diego's biotech corridor (Torrey Pines area) is one of the three largest in the US; life science employers face intense talent competition with the Bay Area and Boston.
