Bosnia and Herzegovina’s population in 2025 is about 3.1 million ; one widely cited estimate gives 3,100,000.

Another 2025 estimate puts it at 3,181,557 , so the exact figure depends on the source and projection method used.

Why the number varies

Population counts for a given year are often modeled estimates rather than a single fixed census value, so different organizations can land a bit apart.

Practical answer

  • Best quick answer: about 3.1 million.
  • More specific estimate: 3,181,557 in 2025.

The short version is that Bosnia and Herzegovina in 2025 has roughly 3.1 to 3.2 million people.
