Migrants are disproportionately represented among suspects of aggression and violence against care providers in the Netherlands, according to an analysis by economist Dr Jan van de Beek using official police and population data.
Van de Beek’s calculations are based on a report commissioned by the Ministry of Justice and Security and the Scientific Research and Data Center (WODC) and published in November 2025. The study was carried out by policy research firm DSP-groep in cooperation with Ipsos I&O and links police records on violence against frontline workers to anonymized microdata from Statistics Netherlands (CBS).
Using the report’s underlying tables, Van de Beek measured how often suspects from different countries of origin are registered for aggression and violence against police officers, municipal enforcement officers, firefighters, and ambulance staff, compared with people of Dutch origin.

— Dr. Jan van de Beek (@demo_demo_nl) January 21, 2026The analysis shows extreme overrepresentation in some groups. Suspects of Somali and Eritrean origin were registered around 15 times more often than people of Dutch origin, after correcting for population size. High levels of overrepresentation were also found among suspects of Moroccan origin, and people from the former Dutch Antilles and Suriname. Several other non-European groups were also above average, while suspects of German and Belgian origin were at or below the Dutch baseline.
The dataset covers 24,488 unique suspects. According to the report, people of Dutch origin account for 47 percent of all suspects overall, while several migrant groups make up a far larger share of suspects than their share of the population.
The authors of the report caution that the figures do not point to a single cause, emphasizing that factors such as age, gender, socioeconomic vulnerability, and alcohol and drug use must be considered. However, Van de Beek suggests there is irrefutable proof that migrants from certain countries of origin are more prone to violence than the indigenous population.
Van de Beek’s work has long sparked criticism from the Dutch establishment. In 2021, he co-authored ‘Borderless Welfare State: The Consequences of Immigration for Public Finances,’ which concluded that immigration as a whole has had a negative net fiscal impact on the Netherlands.
That study estimated the total net cost of immigration between 1995 and 2019 at around €400 billion, or roughly €17 billion per year. It found that migrants arriving for work or study, particularly from Western countries and East Asia, were more likely to make a positive contribution, while asylum and family reunification migrants were more likely, on average, to make a negative one, largely due to lower educational attainment.
The Dutch economist, however, appears rather dismissive of criticism from the mainstream media, recently posting on X, “You’re in trouble with some Dutch journalists if you don’t quite operate within the ‘correct migration narrative.'”
The criminal consequences of integration in the Netherlands came to the fore last week after the exposure of a multiculturalism experiment in Amsterdam that went wrong.

— Remix News & Views (@RMXnews) January 19, 2026The Stek Oost integration programme in the Watergraafsmeer district, launched in 2018, saw 125 refugees live together with 125 young students, but soon turned into a nightmare. Young men, predominantly from Syria, Eritrea, and Somalia, were housed at the facility that was soon plagued by reports of sexual assaults and physical violence.
In 2019, a Syrian was accused of raping a student in his room. In 2023, there was a gang rape investigation. Between 2018 and 2021, one refugee was accused of six sexual assaults. Another refugee threatened students with a kitchen knife.
The housing association warned authorities on multiple occasions, but the authorities ignored the complaints, citing difficulties with eviction.
Despite sparking global news coverage documenting violence, sexual assaults, and drug-related crimes in the shared living integration project, the city of Amsterdam refuses to shut the project down.
According to public broadcaster BNNVARA, the municipality has rejected calls to shutter the facility early and plans to run the project until its scheduled end in April 2028.
