The Ukraine War now represents Europe’s biggest refugee crisis since World War II. Recent reports from UNHCR, the UN Refugee Agency, state that more than 5 million people have fled the country since Russia invaded on February 24, 2022.
According to the agency, Ukraine had a population of 44 million prior to the war. Now, two months after the invasion began, more than 7 million people have been internally displaced, in addition to the 5.7 million who had fled the country as of May 3, 2022. UNHCR states that another 13 million people are likely to be trapped in war-torn areas, with little-to-no access to food, medical care, water, or housing.
Comments made by UNICEF Spokesperson James Elder emphasized the gravity of the crisis, who in a press briefing at the Palais des Nations in Geneva on March 15 stated “Every single minute, 55 children have fled their country. A Ukrainian child has become a refugee almost every single second since the start of the war.”

The refugee crisis intensified in late April as Russia initiated a large-scale offensive in eastern Ukraine, near the Donbas region. The Donbas region is home to the Siverskyi Donets Donbas (SDD) canal, which supplies water for the 6 million Ukrainians living in-and-around the region. Parts of the system stopped functioning immediately after the invasion in February, when power systems across the country became unstable. An article in Quartz states that “[a]ny scenario in which Donbas’ water is weaponized and restricted, either by Russia or Ukraine, is a worrying one for the citizens who depend upon the SDD canal,” underscoring the potential threat that Russia’s offensive has on Ukrainian infrastructure.
The number of civilian casualties and the destruction of critical infrastructure continues to amass as the conflict escalates, forcing people to flee their homes in search of safety and assistance. In response to the emergency, CrisisReady generated and disseminated maps highlighting the evolving changes in population densities across Poland, Hungary, Slovakia, and Romania, all of which are situated along the western border of Ukraine. The maps generated use human mobility data as proxies to estimate and predict the movement of refugees as the war unfolded.
More recently, CrisisReady developed an interactive dashboard that provides signals to changing movement patterns in Poland, Hungary, Slovakia, Romania, and The Republic of Moldova on a continual basis. Its role is to help augment or add-to existing operational updates, conversations, and humanitarian information products being used to support those displaced by the war in Ukraine.
