International visitors drove this growth. According to Visit Berlin, around 42 per cent of travellers to Berlin came from abroad. Last year, the proportion was just over a third. The most important countries of origin are the UK and the Netherlands. German visitors primarily come from the federal states of North Rhine-Westphalia, Bavaria and Baden-Württemberg. This was the result of a long-term survey conducted by the company among around 1,700 tourists between May 2023 and April 2024, according to which the guests were 40.3 years old on average and therefore younger than the national average for other cities (44 years).
