Census Business Formation Statistics count applications for an employer identification number, not seasonally adjusted. They run ahead of state registrations and include sole proprietors that never file with the state, so the two series measure different steps of starting a business.
Websites and domain age
Based on 185 business filings from Oct 2025 to Aug 2026, with domain registration dates from public WHOIS/RDAP records for 48 of them. The latest two months are left out because websites are often found weeks after a filing. A domain much older than the filing usually means an existing operation formalizing, not a brand-new idea.
