Francophone Voter Volatility in Belgium Hits Record High

More than half of Francophone voters in Belgium cast ballots for a different party in the 2024 federal elections compared to 2019, according to a landmark study published by the Centre de recherche et d’information socio-politiques (CRISP). The research, released on June 9, reveals that 51% of voters in Wallonia and Brussels switched party allegiances between the two elections — the highest level of electoral volatility recorded since CRISP began tracking this data in 1985.

A Historic Reversal

The findings, published in Courrier hebdomadaire No. 2686, mark a dramatic shift in Belgian electoral behavior. Between 2014 and 2019, 35% of Francophone voters changed parties. That figure has now jumped to 51%, representing a 16-percentage-point increase in voter fluidity.

In a striking reversal of historical patterns, Flemish voters are moving in the opposite direction. In Flanders, 37% of voters switched parties in 2024 — down from 44% in 2019, marking the first decline in electoral mobility in the region since CRISP began its longitudinal study four decades ago.

“For the first time since the beginning of our research on the subject, in 1985, we note a decline in electoral mobility in Flanders,” the study’s authors stated, as reported by La Libre Belgique. “In Francophone Belgium, we observe the opposite trend, with electoral volatility reaching a historic high.”

The result, the researchers noted, is “an unprecedented configuration” where the volatility of the Francophone electorate now exceeds that of its Flemish counterpart for the first time.

Youth Disengagement and the Green Vote Collapse

The study, authored by Marc Swyngedouw, Daan Delespaul, Koen Abts, Cecil Meeusen, and Bart Meuleman, also uncovered troubling trends among first-time voters. Nearly four out of ten first-time voters in Francophone Belgium did not participate in the 2024 elections — a high abstention rate largely attributed to the Brussels-Capital Region, according to L’Avenir.

Perhaps the most dramatic finding concerns the Green party, Ecolo. Among first-time voters, Ecolo’s support collapsed from 42% in 2019 to just 3% in 2024 — a loss of 39 percentage points that the study’s authors describe as a literal collapse, as 7sur7 reported.

What’s Driving the Volatility?

The surge in voter volatility reflects a broader erosion of traditional party loyalty in Francophone Belgium. The 2019 elections led to a prolonged government formation process that ultimately produced the De Croo government — a seven-party coalition that excluded the largest party, N-VA. The 2024 elections then saw the rise of the “Arizona coalition,” a five-party alliance led by Prime Minister Bart De Wever (N-VA).

Several factors appear to be driving the trend:

  • The decline of traditional centrist parties, as voters increasingly abandon established political brands
  • The rise of the right-wing MR (Mouvement Réformateur) under Georges-Louis Bouchez, which has reshaped the Francophone political landscape
  • The transformation of the former CDH into Les Engagés, a centrist repositioning that has attracted some voters while repelling others
  • Ecolo’s post-government collapse, after the Greens’ participation in the De Croo government led to a dramatic loss of support, particularly among young voters
  • Growing dissatisfaction with traditional political parties across the ideological spectrum

Implications for Belgian Democracy

The findings carry significant implications for Belgium’s political future. High electoral volatility can signal weakening party attachments and growing voter dissatisfaction — trends that may lead to more fragmented parliaments and increasingly complex coalition negotiations.

For Ecolo, the collapse among first-time voters represents an existential challenge. The party must urgently rebuild its appeal to young voters, who had been a core constituency just five years earlier.

More broadly, the high abstention rate among first-time voters — particularly in Brussels — raises concerns about long-term democratic engagement. If nearly 40% of new voters are opting out of participation entirely, the legitimacy of democratic institutions could face growing pressure in the years ahead.

The growing divergence between Francophone and Flemish electoral behavior also raises questions about federal cohesion. As the two main linguistic communities of Belgium move in opposite political directions, the challenge of forming stable national governments may only intensify.

What to Watch For

The CRISP study provides a valuable longitudinal dataset spanning four decades of Belgian electoral behavior. Future research will likely explore which specific parties are gaining and losing from this voter fluidity, the extent to which Brussels is driving the volatility figures, and how these trends compare with other European countries experiencing similar voter realignment.

For now, the message from the data is clear: Francophone voters in Belgium are more unpredictable than ever, and the country’s political parties must adapt to a new era of unprecedented voter fluidity.
