record membership growth across parties
The total number of political party members in the Netherlands reached 448,100 on January 1, 2026, the highest level since the 1980s [1]. This marks an increase of 57,000 members compared to the previous year [2]. The rise represents a significant reversal of decades-long declining trends in party membership [1]. Nearly all parliamentary represented parties reported membership gains during 2025 [3]. The data comes from the annual survey conducted by the Documentation Centre Dutch Political Parties (DNPP) at the University of Groningen [1].
forum voor democratie holds largest base
Forum voor Democratie (FvD) remains the largest political party by membership, with slightly over 70,000 registered members [1]. The party submitted an auditor’s verification to support its reported figures [1]. Despite being the smallest major party in terms of seats in the Second Chamber, it maintains the broadest formal membership base [1]. The Party for Freedom (PVV), which won the most seats in the 2025 election, does not allow formal membership—only Geert Wilders himself is officially a member [1].
groenlinks and pvda see strongest growth
GroenLinks recorded the largest numerical increase, adding 16,258 new members in 2025 [1]. The Labour Party (PvdA) followed closely behind with similar growth [1]. As a percentage, GroenLinks grew by approximately 35 percent, while PvdA expanded by 33.5 percent [2]. Both parties saw accelerated recruitment ahead of their planned summer merger [1]. Dual memberships between the two parties rose significantly during this period [1].
other parties show varied performance
JA21 increased its membership from 3,637 to 4,860, a gain of 33.6 percent [2]. DENK welcomed almost 30 percent more members, reaching a total of 5,300 [2]. On the decline, BBB lost 7.9 percent of its membership base [1]. NSC, following internal leadership changes and electoral loss, shed one-third of its members after exiting parliament in November 2025 [1]. Most established parties experienced net growth despite differing trajectories [2].
experts analyze drivers of renewed engagement
Researchers attribute the overall surge to heightened media coverage surrounding the October 2025 general election [2]. Historically, elections correlate with temporary increases in party affiliation [3]. However, scholars describe the 2025 growth as “particularly strong” even by those standards [1]. Political scientist Carla Hoetink notes the absence of breakthrough new parties, making organic growth more remarkable [1]. There is growing scholarly interest in whether digital outreach and generational shifts in activism play a role [1][3].
methodology and reliability concerns
The DNPP relies on self-reported membership data from each party annually [1]. While considered done in good faith, these figures cannot be independently verified [1]. Since 2009, subsidy eligibility has depended on members paying at least €12 and having voting rights, creating some standardization [3]. An updated accounting protocol introduced in 2025 mandates stricter audits of membership records and payment verification [3]. Full implementation and impact remain under review [3].
