Facebook usage in the U.S. varies significantly by state, with California, Texas, and New York leading in total users while many states show consistently high population penetration rates near 50%.
USA has over 148 million people registered on Facebook which makes it by far the #1 country on Facebook in terms of users.
How does each state perform on Facebook and what is the value of penetration to population?
Find out in the following chart:

As we can clearly see from the chart, California is the leading state with more than 19 million people and penetration to population close to 52 %. That means every second Californian has an account on Facebook. If California were an independent country, it would have placed itself in the 9th position in the world! Right between Mexico and Italy.
The second and third highest numbers of users on Facebook belong to Texas (11 million) and New York (10 million). These are the only states (together with California of course) that conquered the 10-million barrier. The rest of the positions belong to Florida (8.8 million), Illinois (6.2 million), Pennsylvania (5.8 million), Ohio (5.4 million), etc.
An interesting fact is that most of the states in the TOP 20 score quite high values in the penetration to population percentage. This number is very close to 50 % in many states. The only exceptions in the top 20 lists are Arizona (42 %) and Virginia (38 %).
As the total number of users in the US will eventually slowly stagnate, it will be interesting to watch how each state will develop in terms of the total number of users and more importantly – evolution of penetration to population.

California ranks first with more than 19 million users, followed by Texas with around 11 million and New York with approximately 10 million. These three states stand out as the only ones surpassing the 10-million-user mark, with Florida, Illinois, and Pennsylvania following behind.
Penetration rate refers to the percentage of a state’s population that uses Facebook. It provides a clearer picture of adoption than total user numbers alone, showing how deeply embedded the platform is within a given population.
Many of the top 20 states have penetration rates close to 50%, meaning about half of their populations are active on Facebook. This indicates that Facebook usage is not just concentrated in large states but is broadly adopted across the country.
Yes — while most top states have high penetration, some like Arizona (around 42%) and Virginia (around 38%) fall below the ~50% range, showing that adoption levels can vary even among highly ranked states.
California not only has the largest number of users but also a high penetration rate of around 52%, meaning roughly one in two residents uses Facebook. If considered independently, its user base would rank among the largest globally, underscoring both its scale and the platform’s deep integration into daily life within the state.
