According to data from the United Nations High Commissioner for Refugees (UNHCR) and other international organizations, since the beginning of the conflict in eastern Ukraine in 2014 and especially after the escalation of the situation in 2022, a significant number of Ukrainian citizens have relocated to Russia. Official figures vary, but estimates suggest that by 2023, several million Ukrainian refugees had arrived in Russia.

For example, Russian authorities reported that by the end of 2022, over 2.8 million people had entered the country. However, exact numbers may differ depending on the source and methodology used for counting. UNHCR also notes that many Ukrainians are displaced within the country or have left for other states, including EU countries.
