Nearly4.2millionUkrainians have fled their country since Russia's invasion began on February 24, with almost 40,000 pouring into neighbouring countries in the past 24 hours, UN numbers show.
The United Nationsrefugeeagency, UNHCR, said Sunday that 4,176,401 Ukrainians had fled in just over five weeks, up 38,559 from the figure given a day earlier.
Women and children account for 90 percent of those who have left Ukraine, with men aged 18 to 60 eligible for military call-up and unable to leave.
The UN's International Organization for Migration (IOM) said that in addition toUkrainianrefugees,nearly205,500 non-Ukrainians living, studying or working in the country have also left.
Nearly6.48millionpeople were meanwhile estimated to be internally displaced within Ukraine as of mid-March, according IOM.
That puts the total number of people displaced by the conflict at well over 10million, or around a quarter of Ukraine's total population.
Before the Russian invasion, Ukraine had a population of 37millionin the regions under government control, excluding Russia-annexed Crimea and the pro-Russian separatist regions in the east.
Children have been disproportionately affected.
The UN children's agency UNICEF said in late March that more than half of the country's estimated 7.5millionchildren had been displaced -- 2.5millioninternally and twomillionabroad.

The Moldovan border is the closest to the major port city of Odessa, which was hit by air strikes Sunday morning.Some 392,933 Ukrainians have crossed into the non-EU state, one of the poorest in Europe.
Most of those who have entered the former Soviet republic of 2.6millionpeople, sandwiched between Ukraine and Romania, have moved on.
But around 93,000 have stayed, with the UN Development Programme saying that some 80 percent are being housed by private individuals.
