The UN refugee agency UNHCR, on Sunday, said 3,821,049 Ukrainians has fled the country — an increase of 48,450 from Saturday’s figures.
It added that around 90 per cent of them are women and children,
The report says of those who have left, 2.2 million have fled to neighbouring Poland, while more than half a million have made it to Romania. Nearly 300,000 have gone to Russia.
Before the crisis began a month ago, EU member Poland was home to around 1.5 million Ukrainians.
According to AFP, a total of more than 10 million people — over a quarter of the population in regions under government control before the February 24 invasion — are now thought to have fled their homes, including nearly 6.5 million who are internally displaced.
On Thursday, the UN children’s agency, UNICEF, said that 4.3 million children — more than half of Ukraine’s estimated 7.5-million child population — had been forced to leave their homes.
It stated that some 1.5 million children have become refugees, while another 2.5 million are displaced inside the war-ravaged country.
The number leaving daily has fallen well below 100,000 per day, and even 50,000 in recent days, even as living conditions in Ukraine worsen.
The figures do not include citizens of neighbouring states who have left Ukraine to return home.
Here is a breakdown of which neighbouring countries Ukrainian refugees have headed to, as of Sunday afternoon. Russia’s figure relates to end Tuesday:
Six out of 10 Ukrainian refugees — 2,267,103 so far — have crossed Poland, according to UNHCR.
Many people who cross into Ukraine’s immediate western neighbours continue to other states in Europe’s Schengen open-borders zone.
Many are also going in the opposite direction. Border guards said earlier in the week that some 274,000 people have left Poland for Ukraine since the war began.
Some 586,942 Ukrainians have entered the EU member state Romania, including a large number who have crossed over from Moldova, wedged between Romania and Ukraine.
The vast majority are thought to have gone on to other countries.
The Moldovan border is the nearest to the major port city of Odessa.
UNHCR said 381,395 Ukrainians had crossed into the non-EU state, one of the poorest in Europe.
To reduce congestion, organised convoys leave daily from the Palanca crossing for Romania, with the most vulnerable prioritised for transfer.
Some 349,107 Ukrainians have entered Hungary, according to UNHCR.
Some 271,254 refugees have sought shelter in Russia, according to UNHCR figures last updated on March 22.
In addition, 113,000 people had crossed into Russia from the separatist-held pro-Russian regions of Donetsk and Lugansk in eastern Ukraine between February 21 and 23.
Some 272,012 people have crossed Ukraine’s shortest border into Slovakia.
Some 6,341 refugees have made it north to close Russia ally Belarus.
