* No official census: There isn't a specific census or survey that asks Croatians about their English proficiency.
* Varying levels of fluency: Some people might understand basic English, while others are fluent speakers.
* Regional differences: English proficiency might be higher in tourist areas or cities with more international connections.
However, we can make some educated guesses based on available data:
* English is increasingly popular: As in many countries, English is becoming more common as a second language in Croatia due to globalization, tourism, and technology.
* Education: English is often taught in schools, and many Croatians have some exposure to the language.
* EU membership: Croatia is a member of the European Union, which promotes English as a lingua franca.
Overall, it's safe to say that a significant number of Croatians have at least some knowledge of English, with the proportion likely increasing.
