I am looking for the best way to study an industry by NAICS code across time and geography. Example: QSRs in Columbus, Ohio sinceredactedI want to understand year over year revenue growth, CAGR, margins, valuation multiples, business count, salaries and broader market trends. In practice, I am trying to answer questions like: • Has this sector actually grown in this market over time? • Are margins improving or compressing? • Are transaction multiples expanding or just broker fantasy fiction? • Is the market fragmented, stable, or getting rolled up? What data source or workflow are people using for this? I have looked at IBISWorld, Census, BizComps, DealStats, and similar tools, but I am still looking for the cleanest repeatable approach. Any recommendations would be helpful.
