Methodology

Each figure is the number of businesses listed on Google Maps that are in the Leadz database under the Advertising Agency category as of December 14, 2025.

This is not a census or a licensing count. A business can be missing from the database or filed under a different category. State figures may not add up to the US figure because some listings are outside the 50 states and the District of Columbia or have no state on record.

Per-capita figures divide each count by the 2020 Census resident population of the state (US figure: the 50 states and the District of Columbia) and multiply by 100,000. Share of US total divides each state count by the US figure.
