Meanwhile, 70 percent of respondents believe that Russia's invasion of Ukraine poses a direct threat to Poland’s security, the study by pollster CBOS found.
The survey was carried out from August 14 to 27 on a sample of 1,024 respondents, Polish state news agency PAP reported.
The study also found that 38 percent of Poles were providing support to Ukraine and its people amid the Russian invasion, which is nearing its 19th month.
More than 15.5 million people have crossed into Poland from Ukraine since the start of the war in February last year, the Polish Border Guard agency reported on Thursday.
Meanwhile, nearly 13.8 million people have left Poland for Ukraine since Russia invaded on February 24, 2022, the agency also said.
Poland's President Andrzej Duda told public broadcaster Polish Radio earlier this year that the country was home to an estimated 3 million Ukrainians, including those who arrived before the war.
The Polish presidential office said in March 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.
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.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
Thursday is the 568th day of Russia’s war on Ukraine.
