Nantucket Crime Rate: What Residents and Visitors Need to Know
Nantucket is genuinely safe by most measures. The island’s overall crime rate sits roughly 45% below the national average, making it one of the safer communities in Massachusetts for both year-round residents and summer visitors. The Nantucket Police Department and the 2025 Town of Nantucket Annual Report both confirm that overall crime statistics have remained stable in recent years. That said, property crime, particularly larceny and theft, is the category that deserves your attention, especially during the busy summer season when the island’s population swells from its year-round residents to more than three times that during summer.

How does Nantucket’s crime rate compare to state and national averages?
The numbers tell a reassuring story, though a few details are worth understanding before you take them at face value.
| Metric | Nantucket | U.S. National Average |
|---|---|---|
| Overall crime rate (per 100k) | 1,115.7 | Significantly higher |
| Violent crime rate (per 100k) | 202.9 | — |
| Property crime rate (per 100k) | 912.8 | — |
| Chance of violent crime | 1-in-612 | 1-in-612 |
| Chance of property crime | 1-in-85 | 1-in-85 |
FBI-derived figures reported by CrimeByCity place Nantucket’s 2024 total crime rate at 1,115.7 per 100,000, with violent crime at 202.9 per 100k and property crime at 912.8 per 100k. Aggregated sources estimate this results in a roughly 1-in-612 chance of violent crime and a 1-in-85 chance of property crime for residents.
For visitors, property crime is the more relevant number. Theft from unlocked vehicles, bikes left unsecured, and vacation-home break-ins account for the bulk of incidents. For residents, the violent crime rate matters more for long-term planning, and at 202.9 per 100k, it remains well below the national estimate.
Pro Tip: Per-capita rates on Nantucket are calculated against the year-round population of roughly 14,000. During summer, the real population is closer to 50,000, which means the true per-person risk during peak season is considerably lower than the published rate suggests.
What do recent crime trends on Nantucket look like?
The clearest trend over the past few years is not a spike in crime. It is a shift in how the Nantucket Police Department operates.
- Arrests declined significantly from FY2023 to FY2025. Total arrests dropped from 591 in FY2023 to 452 in FY2025, according to local reporting from Nantucket Current.
- Motor vehicle stops increased notably in the same period. Stops increased from 2,158 to 3,581, reflecting a deliberate shift toward traffic enforcement rather than a drop in public safety activity.
- Overall crime statistics have remained stable. The 2025 Town Annual Report describes crime levels as steady, without a structural upward trend in violent or property incidents.
- Violent crime has trended downward over five years. Travel safety sources note a multi-year reduction in violent crime, consistent with the island’s historically low baseline.
- Seasonal volatility is real. A handful of additional incidents during a busy July weekend can move the annual per-100k rate noticeably when the denominator is a small year-round population. Multi-year averages are more reliable than any single-year snapshot.
The seasonal population dynamic is a key factor in reading these numbers correctly. What looks like a year-over-year crime increase may simply reflect a busier tourist season rather than a genuine safety deterioration.
Pro Tip: When comparing Nantucket’s crime figures across years, check whether the source uses year-round or seasonal population as its base. The difference can change a rate by a factor of three or more.
Which crimes are most common on Nantucket?
Property crime drives the overall count. Violent incidents are comparatively rare, and when they do occur, they often involve people who know each other rather than strangers.
- Rental scams — Not a traditional crime category in FBI data, but a real risk for visitors booking accommodations. Fraudulent listings targeting summer renters have been flagged by local sources.
Pro Tip: Lock your bike every time, even for a quick errand. Bicycle theft is one of the most common and underreported property crimes on the island during summer, and recovery rates are low.
Are some parts of Nantucket safer than others?
Nantucket is a small island, and the differences between neighborhoods are less dramatic than in a large city. Still, a few patterns are worth knowing.
- Downtown Nantucket (near the harbor and Main Street) sees the highest concentration of foot traffic and, accordingly, the most reported theft and minor incidents. Summer crowds create more opportunity for petty crime.
- Residential neighborhoods away from the commercial core (Madaket, Siasconset, Polpis) report fewer incidents. Lower density and less tourist activity translate to a quieter day-to-day experience.
- Seasonal rental clusters can see spikes in noise complaints and minor property incidents during peak summer weeks, particularly in areas with high short-term rental density.
Third-party platforms like NeighborhoodScout and Niche publish neighborhood-level safety grades and crime maps for Nantucket that residents and prospective movers use regularly. Nextdoor’s Nantucket community feeds offer near-real-time reports from neighbors, which is often more current than annual data. CrimeGrade.org also publishes a safest-places breakdown for Nantucket with block-level detail.
One important caution: in a community this small, a single incident in a quiet neighborhood can double or triple that area’s annual rate. A neighborhood with two reported thefts in a year is not meaningfully less safe than one with zero. Small numbers make rates volatile, so treat neighborhood-level scores as directional, not definitive.
What recent incidents and local news tell you about safety
The local picture over the past two years is one of stability rather than alarm.
- The African Meeting House vandalism investigation — (a 2018 racially motivated graffiti incident) resulted in an independent review completed in 2025, underscoring the community’s commitment to accountability even for older cases.
The decline in arrests alongside a rise in motor vehicle stops reflects a deliberate policing strategy, not a loss of public safety capacity. The department is doing more enforcement work, just in a different category.
Pro Tip: Follow the Nantucket Current for the most timely local crime and police reporting. It covers incidents, police statements, and town meeting decisions faster than annual reports.
Where do the numbers come from and how are they calculated?
Understanding the sources behind any crime statistic helps you read it correctly.
| Source | Coverage | What It Provides |
|---|---|---|
| FBI UCR / NIBRS | Annual, national | Standardized incident counts by crime type, per-100k rates |
| Mass.gov EOPSS | Annual, state | Massachusetts NIBRS data from local agencies, state comparisons |
| Town of Nantucket Annual Report | Annual, local | Local police activity, arrests, traffic stops, population context |
| DoorProfit / CrimeByCity | Aggregated, ongoing | Comparative rates, chance-of-victimization figures |
| NeighborhoodScout / Niche | Aggregated, ongoing | Neighborhood-level grades and maps |
A few methodology points matter here. Per-100k rates use the year-round population of roughly 14,000 as the base, which inflates risk during summer when the real population is three to four times higher. The FBI’s Uniform Crime Reporting program counts reported incidents, not convictions, so unreported crimes (common with minor theft) are not captured. Arrest counts and incident counts measure different things: a drop in arrests does not automatically mean fewer crimes occurred.
For the most reliable picture, cross-reference the Town Annual Report (local operational detail) with FBI-derived aggregators (national context) and state data from EOPSS (Massachusetts comparison).
What the Nantucket Police Department and town report say
The 2025 Town of Nantucket Annual Report describes overall crime statistics as stable, with increased investment in traffic enforcement and specialty policing roles. That framing matters because it signals that the department is not responding to a crime surge. It is proactively expanding enforcement capacity in areas like road safety.
The sharp rise in motor vehicle stops from 2,158 to 3,581 between FY2023 and FY2025 reflects an intentional departmental priority, not a reaction to worsening conditions. More stops mean more visibility on the roads, which tends to deter other opportunistic offenses.
- Arrests declined 24% from FY2023 to FY2025, from 591 to 452.
- Motor vehicle stops rose 40% in the same window, from 2,158 to 3,581.
- Specialty roles and traffic enforcement were highlighted as growth areas in the Annual Report.
- Service calls increased, indicating the department is handling more community-level requests even as formal arrest counts fall.
This pattern, fewer arrests alongside more enforcement activity, is a known outcome of community-policing approaches. It does not indicate that crime is going unaddressed.
Practical safety tips for residents and visitors
Most precautions on Nantucket are straightforward. The island’s risks are concentrated in property crime, and the steps that reduce your exposure are simple.
For visitors:
- Lock your rental car every time, even in driveways. Motor vehicle theft and theft from vehicles are among the more common reported incidents.
- Secure bikes with a quality U-lock. Bike theft is frequent and rarely results in recovery.
- Store valuables out of sight in your rental property. Off-season burglaries often target homes that look unoccupied.
- Verify rental listings through established platforms before sending any payment. Fraudulent listings targeting summer visitors are a documented risk.
- Save the Nantucket Police non-emergency line before you arrive: (508) 228-1212.
For residents:
- Use a home security system or smart-lock setup, particularly if you leave for extended periods.
- Report suspicious activity through Nextdoor’s Nantucket community or directly to the police non-emergency line.
- Plan for island-specific emergencies: power outages, coastal flooding, and severe weather are safety concerns that rank alongside street-level crime for year-round residents.
Pro Tip: If you are relocating to Nantucket and need secure storage during the transition, using a licensed, insured storage provider reduces the risk of loss or damage to your belongings during the move-in window.
Pro Tip: Before peak hurricane season (August through October), confirm your emergency kit includes a battery-powered radio, three days of water, and a backup charging solution. Island infrastructure can be disrupted faster than mainland communities during major storms.

A local perspective on reading Nantucket’s safety numbers
The most common mistake people make when reading Nantucket’s crime statistics is treating them the same way they would treat numbers from a city of 100,000. They cannot be read the same way.
When the year-round population is 14,000 and the summer population exceeds 50,000, a single busy weekend can move the annual rate in ways that look alarming on paper but mean almost nothing in practice. The per-100k rate is a useful comparison tool, but it was designed for stable populations. On a seasonal island, it needs context every time it is cited.
The more telling signal from recent years is the policing data: arrests down, traffic stops up, service calls up. That combination suggests a department that is active and shifting resources toward prevention and visibility rather than reactive enforcement. For anyone deciding whether to visit or move to Nantucket, that is a more meaningful indicator than a raw crime rate number.
For summer visitors, the practical calculus is simple. Lock your bike. Lock your car. Verify your rental. Those three steps address the vast majority of incidents that affect people who are not already connected to the local community. For prospective residents, the data supports a positive picture, with the caveat that island life comes with its own category of risk, weather, infrastructure, and isolation, that does not show up in any crime report.
