The survey found that 72.8 percent of respondents support remaining in the EU, including 50.7 percent who said Poland should “definitely” stay and 22.1 percent who said it should "rather" remain.
Support for continued EU membership was strongest among women, people aged 60-69, residents of large cities with populations above 250,000, and those with a higher education, Polsat News reported.
Meanwhile, 22.9 percent of respondents favoured leaving the bloc—with 16.2 percent saying Poland should "rather" exit and 6.7 percent supporting a definite withdrawal.
The remaining 4.3 percent were undecided.
Among those strongly backing an exit, people aged 50–59 and residents of smaller towns with populations below 50,000 were most represented, Polsat News said.
The poll also asked respondents about the balance of EU membership for Poland. A majority, 56.5 percent, said the country has benefited more than it has sacrificed, while 18.1 percent said the opposite.
A further 16.7 percent said the gains and losses have been balanced, and 8.7 percent were unsure.
Views varied sharply along political lines. Among supporters of the opposition Law and Justice (PiS) party, more respondents said EU membership had brought losses than benefits—31.1 percent versus 11.8 percent.
By contrast, backers of the ruling Civic Coalition (KO) were overwhelmingly positive, with 98.6 percent saying EU integration has been beneficial.
The survey was conducted between March 19 and 22 on a representative nationwide sample of 1,000 adults through telephone interviews.
A former government minister warned this month that growing anti-EU sentiment on the Polish right could push the country toward a British-style rupture with the bloc.
