Since February 24, 2022, when Russia invaded its neighbour, almost 10.8 million people have crossed into Poland from Ukraine, according to the Polish Border Guard agency.
Meanwhile, more than 8.9 million people have left Poland for Ukraine since the start of the Russian invasion, the agency said.
On Friday, around 31,000 people crossed from Poland into Ukraine, it also reported.
Poland's President Andrzej Duda told a global democracy summit on Wednesday that "today, Poland is home to more than 3.5 million Ukrainians."
The Polish presidential office said last month that around 1.3 million war refugees from Ukraine were staying in Poland after many who had fled Russia's invasion moved on to other countries or decided to return to Ukraine.
A deputy prime minister said in December that Poland was home to more than 2 million Ukrainians, including those who arrived before the war.
In March last year, Poland enacted a measure to offer wide-ranging support to Ukrainians escaping the Russian invasion of their country.
The measure grants them residence rights and ensures access to education, healthcare and social benefits.
Eighty-one percent of Poles are in favour of accepting refugees from war-torn Ukraine, according to a recent survey.
Saturday is day 402 of Russia’s war on Ukraine.
