According to official sources, 8.5 million crossings into Ukraine's western neighbor via foot, bus, car or train were recorded, largely caused by the Russia-Ukraine war. Border crossings into Russia have also increased significantly since the first weeks of fighting. According to official information, 2.9 million crossings to Russia from Ukraine took place, more than in Hungary, Romania, and Moldova, which bore the brunt of the refugee wave for a long time. However, the most recent data for border crossings into Russia is from October 3, 2022, so the actual values are likely to be higher now due to the ongoing hostilities in the country.
