A majority of Luxembourgers back further enlargement of the European Union, though support is below the levels seen in northern Europe, according to a Eurobarometer survey published last week.

Across the EU, 56% of citizens said they favoured future enlargement, with strong support among younger people.

In Luxembourg, 60% of respondents were in favour, just above the halfway mark but below the enthusiasm recorded in countries such as Sweden (79%) and Denmark (75%). Opposition in Luxembourg stood at 42%, with 5% undecided.

Sentiment against EU enlargement was strongest in Czechia and France, where only 43% backed enlargement, and in Austria, where 45% supported it. In Germany, fewer than half of respondents (49%) expressed support, leaving Europe’s largest economy among the more sceptical member states.

When asked which candidate countries they would like to see join the bloc once conditions are met, Luxembourgers were most favourable towards Montenegro (57%), making the Grand Duchy one of the seven EU countries where it ranks highest.

Support for Ukraine’s accession was also higher than the EU average: 56% in Luxembourg compared with 52% across the EU. It was highest in Sweden with 91%.

Concerns among Luxembourg respondents mirrored broader European trends. Citizens cited migration, corruption and the cost to taxpayers as risks of expansion.

At the same time, they saw benefits in a larger market for EU businesses, more choice for consumers and a stronger EU role globally.

The data underlines the generational split: younger Luxembourgers, like their peers elsewhere in the EU, are more supportive of enlargement than older age groups. Education levels also play a role, with those still studying showing the highest levels of backing.

The survey was conducted between February and March 2025, covering more than 26,000 EU residents, including 504 respondents in Luxembourg.
