The UN migration agency now estimates that more than 11 million people have fled their homes in Ukraine since Russia's invasion.
The International Organization for Migration, in its first such full assessment in three weeks, reported Tuesday that more than 7.1 million had been displaced within Ukraine as of April 1. That comes on top of the figure of more than 4 million who have fled abroad, reported by the U.N. refugee agency.
IOM said more than 2.9 million others are actively considering "leaving their place of habitual residence due to war."
Ukraine had a pre-war population of 44 million.
The tally marked an increase from IOM's tally in mid-March of more than 9.7 million displaced internally in Ukraine or driven abroad.
