Austria's population of 9 million is growing thanks to immigration, which makes up 27.8% of the total. As birth rates fall, immigration becomes essential.

According to the Office of National Statistics, immigration has become the main factor in Austria's population growth, which has increased by 38.4% in the last decade. Today, 2.51 million residents are of immigrant origin, and the proportion has risen from 21.4% to 27.8%. Austria faces more deaths than births, and without immigration, the population could fall significantly. The population is expected to exceed 10 million by 2069, largely due to immigration.
