Entry-Level Open-Water Scuba Diving Certification Numbers & U.S. Market Trends & Statistics

How many new entry-level open water divers are certified annually in the USA, by state, region & per capita?

The Diving Equipment & Marketing Association (DEMA) surveys the number of entry-level open water scuba certifications by a limited number of dive training agencies (PADI, NAUI & SDI) and then extrapolates to estimate the total number of entry-level scuba diving certifications per quarter and per year in the USA and per state.

Open Water Scuba Certifications by U.S. State & Region

If you operate a local dive shop in the USA, you are more interested in the size of the industry in your neck of the woods—or neck of the oceans! For you, the following Tables provide the number of entry-level open water certifications by state, as estimated by DEMA.

A better way of evaluating your market potential would be to know the participation rate by state in addition to the number of certifications, but this information is currently unavailable.

Please participate in our dive industry market surveys so that we can eventually provide you with more market data specific to your geographic region.

Keep in mind that a high percentage of scuba divers do their certification course while on vacation in a tropical destination. Therefore, even if a geographic region has a low level of open water certifications, you may still have a good market for selling gear and travel to scuba divers who don’t dive locally.

Scuba Certifications per Capita by State

In the following table, we ranked U.S. states by the number of entry-level open water scuba certifications per capita (per million of citizens) in 2023.

As a reference point for how “outdoorsy” the state’s residents are, we compared open water certs per capita to each state’s outdoor recreation value-added as a percent of the state GDP, using data from the U.S. Bureau of Economic Analysis (BEA).

  • Certs per M” = Number of entry-level open water certifications in that state per million of citizens in 2023
  • % of GDP” = Outdoor recreation value added as a % of the state GDP in 2023

*The outdoor recreation value added as a % of the state GDP was not available for the U.S. Virgin Islands and Puerto Rico.

**The outdoor recreation value added as a % of the state GDP in 2023 was 1.7% for Virginia and Maryland, and 0.9% for D.C.

It is interesting to note that landlocked states like Utah and Colorado issue more open water certifications per capita than Florida. And California comes lower than many other landlocked states. Access to water is not everything!

Although these numbers indicate the number of entry-level open water certifications per capita (per million of citizens), it does not mean that these certifications were done for residents of that state.

A high percentage of scuba divers do their open water certification course while on vacation in a tropical destination. Therefore, even if a geographic region has a low level of open water certifications, there may still be a good number of active divers – they simply do not dive locally or, at least, did not get their C-card locally.

And vice versa, in a state like Hawaii, a good percentage of the open water certifications are done to tourists visiting from out of state and out of the country.
