But there was no running water, no electricity and only an outhouse for toilets. The camp had never been winterized, and there were holes in some of the cabins’ roofs. Everyone just made the best of it because no one believed they would be there for more than a few weeks, Kuprina said.

That was nine months ago, and she and her family are still living at Romashka. They are trying to accept that they may need to begin calling Kharkiv home, she said. “It’s looking like we’re not going back to Donetsk anytime soon,” she said. “Even if we could, what would we go home to? There is nothing left of our street.”

Kuprina is one of more than 1 million registered internally displaced people, or IDPs, who have been uprooted by the violent conflict in Ukraine’s east. In the 10 months since the first wave of IDPs started flowing out of the rebel-held territories, the number of displaced in Ukraine has risen to the most in Europe since the Balkan wars.

The largest group, about 140,000, have fled to Kharkiv, a mostly Russian-speaking region that borders Russia to the north and the Donestk region to the south. Other cities like Kiev, Dnipropetrovsk and Zaphorizha have also received tens of thousands of IDPs. Another 600,000 people have fled the country, many to Russia. There are thousands more people displaced in Ukraine who haven't registered.

The number of IDPs is beginning to weigh heavily on Ukraine’s struggling economy. Near default when the military conflict began in April between Ukrainian forces and Russian-backed rebels, Ukraine’s economy has been weakened by the costs of the war. Each registered IDP who is able to work receives 440 Ukrainian hryvnia (about $15) a month in aid for two months.

International aid organizations and Ukrainian volunteer groups say the number of IDPs continues to grow, despite a Feb. 15 attempt at yet another cease-fire, which was agreed to by both sides but hasn’t halted the fighting that has destroyed vast areas of the country’s former industrial heartland.

Kharkiv Station on Karl Marx Street near downtown is a welcome center for IDPs and recent evacuees from the east. On a cold February morning, several dozen people stood in a line that snaked around a block as they waited for help and advice on where to find food, shelter and work. The center is run by a group of local volunteers, many of whom are IDPs themselves.

Inside the center, dozens more waited to speak to a consultant who could explain how to get registered with the Ministry of Social Policy, where and when they can receive humanitarian food and clothing packets, and the logistics of registering their children in the Kharkiv school system.

The thousands of IDPs are beginning to test the patience of war-weary Ukrainians, who faced high unemployment and inflation before the crisis began. With thousands of IDPs looking for jobs and housing, vacancies are scarce.

Some find temporary jobs in construction, grocery stores or day cares through postings at the IDP center or online listings. The pay isn’t much, but it helps many get back on their feet, said Olga Kianovskaya, 26, who evacuated the Luhansk region in May, settled in Kharkiv and now volunteers at the station’s job search center.

“It’s harder for the older generations because they aren’t as willing to let go of what they’ve left behind,” she said. “For my generation, we have more of a positive attitude to our prospects.”

Discrimination against IDPs is increasingly becoming a problem among the frustrated Kharkiv locals, she said. Everyone in Ukraine is feeling the economic crunch, as the Ukrainian hryvnia has lost 50 percent of its value and inflation continues to rise.

Online postings for rental apartments often add a clause at the end of the property description reading “refugees need not apply.”
