Executive Summary

The Swiss Federal Statistical Office (FSO) recorded a total of 22,957 youth sentences in 2025 – stagnation compared to the previous year. Since 2020, however, the composition of offenses has shifted significantly: traffic offenses increased by 83%, while drug offenses declined by 63%. The number of unconditional custodial sentences doubled, but exclusively among foreign youth without residence permits. Placements outside the home and deprivation of liberty are lasting longer.

Swiss youth crime presents a paradoxical picture: while the overall number remains stable, detailed data reveal a fundamental shift in delinquency patterns. The dramatic increase in traffic offenses (+83% since 2020) points to changing mobility patterns and possibly inadequate prevention. Particularly relevant is the concentration of custodial sentences on foreign youth – a finding that raises questions about integration and residence law policy. The longer detention periods (from 94 to 105 days on average) signal a hardening of enforcement despite relatively stable case numbers.

Detailed Summary

The statistics reveal structural shifts within youth crime. While offenses against the criminal code stagnated at +2% since 2020, extreme fluctuations appear in specialized areas: in addition to traffic offenses (+83%) and violations of passenger transport regulations (+68%), the collapse of drug delinquency stands out (–63%). This divergence can be partially explained by changing life realities – increasing youth mobility explains the traffic increase, while the drug decline may reflect prevention successes or displacement effects.

Sanctioning practices have changed considerably. Reprimands – formal disapprovals by youth prosecutors or courts – now account for over one-third of all sanctions (+36% since 2020). At the same time, unconditional custodial sentences doubled from 258 to 524 cases. However, this increase is not an expression of general hardening: it results entirely from the conviction of foreign youth without residence permits (B or C permits), whose share grew from 161 (2020) to 422 (2025). This points to an enforcement problem – possibly foreigners are punished more harshly or incarcerated more frequently for identical offenses.

The duration of out-of-home placements increased from 151 to 159 days (2024–2025), and for court-ordered measures even to an average of 228 days. Deprivation of liberty extended from 94 to 105 days. These trends indicate longer intervention periods – whether for educational or security-oriented reasons remains unclear from the data.

The FSO has fundamentally revised the Swiss Stat Explorer data platform and now enables granular filtering by canton, type of offense, and sociodemographic characteristics of the convicted.

Key Statements

  • Youth sentences in 2025 stable at 22,957 cases, but offense structure shifting dramatically
  • Traffic offenses +83% since 2020; drug offenses –63% – opposing trends
  • Unconditional custodial sentences doubled, but only among foreign youth without residence permits
  • Out-of-home placements and detention periods continuously lengthening
  • Reprimands as sanctions now dominating with over one-third of all measures

Critical Questions

  1. Data Quality/Evidence: Are the 22,957 sentences completely recorded, or are there regional recording gaps? Is the classification into offense categories based on standardized classifications?

  2. Mobility Hypothesis: The FSO attributes the traffic increase to "increasing mobility" – are empirical data available for this (e.g., vehicle registrations, public transport use among youth)?

  3. Foreigner Overrepresentation: Why do all new custodial sentences concentrate on youth without B/C permits? Is this an expression of selective sentencing practices, different offense profiles, or lack of alternatives (e.g., deportation)?

  4. Drug Delinquency Decline: Is the 63% decrease in drug offenses attributable to prevention successes, decriminalization, or displacement to the dark figure?

  5. Detention Duration Increase: What factors explain the lengthening of out-of-home placements and deprivation of liberty? Are these harsher sentences or longer enforcement periods for identical sentences?

  6. Reprimand Rates: Does the increase in reprimands by +36% constitute more effective diversion, or are more serious cases simply being referred more frequently?

  7. Sociodemographic Blind Spots: What data on gender, origin, and social status are included in the statistics, and do they show disparities in sanctioning?

  8. Causality Mobility-Traffic: Does the increase in traffic offenses correlate with motorization rates or driving license rates among youth?
