The liberalisation of the labour market in Germany in 2017 led to a significant wave of emigration from Bosnia and Herzegovina. The Una-Sana Canton has been the leading region in terms of emigration within the country. In 2021, the Cantonal Ministry of Internal Affairs issued 15,900 certificates of impunity for the purpose of working abroad. This marked an increase from around 13,500 certificates issued in 2017, 14,800 in 2018, and 12,200 in 2019. In 2020, the number of certificates issued was around 9,200. Furthermore, in 2021, approximately 1,500 children enrolled in the first year of primary school, which is 2,000 fewer than 20 years ago.

Due to the proximity to Croatia and its narrow northern outline, various important traffic lines between Zagreb and the Adriatic traverse the Una-Sana canton, such as the railway line Novi Grad-Bihać-Knin. The airport of Željava is located near Bihać and is located right between the Bosnian and Croatian border.
