The Iron Curtain that once divided Europe may be long gone, but the continent today is split by stark differences in public attitudes toward religion, minorities and social issues such as gay marriage and legal abortion. Compared with Western Europeans, fewer Central and Eastern Europeans would welcome Muslims or Jews into their families or neighborhoods, extend the right of marriage to gay or lesbian couples or broaden the definition of national identity to include people born outside their country.

These differences emerge from a series of surveys conducted by Pew Research Center between 2015 and 2017 among nearly 56,000 adults (ages 18 and older) in 34 Western, Central and Eastern European countries, and they continue to divide the continent more than a decade after the European Union began to expand well beyond its Western European roots to include, among others, the Central European countries of Poland and Hungary, and the Baltic states of Estonia, Latvia and Lithuania.

The continental divide in attitudes and values can be extreme in some cases. For example, in nearly every Central and Eastern European country polled, fewer than half of adults say they would be willing to accept Muslims into their family; in nearly every Western European country surveyed, more than half say they would accept a Muslim into their family. A similar divide emerges between Central/Eastern Europe and Western Europe with regard to accepting Jews into one’s family.
