Do you live in one of the most dangerous cities in New Hampshire?

We all watch the news and see reports on Facebook of the latest crimes that happen in our hometowns. But it can be hard to tell at a big picture level how dangerous our town actually is.

No one wants to feel unsafe, and statistically speaking, odds are that where you live is most likely relatively safe. In order to help the good people of New Hampshire — and anyone looking to move to New Hampshire — know just how close they are to danger, we took data from the annual FBI report and did some serious analysis.

The data shows that these ten cities are currently the most dangerous in the Granite State:

  1. Laconia (Photos)
  2. Rochester (Photos)
  3. Somersworth (Photos)
  4. Manchester (Photos)
  5. Lebanon (Photos)
  6. Plymouth
  7. Keene (Photos)
  8. Belmont
  9. Seabrook
  10. Claremont (Photos)

How we determined the most dangerous cities in New Hampshire for 2018?

Every year the FBI release two crime datasets, a preliminary dataset limited to the biggest cities in the country, followed by a more detailed release at the end of the year.

For our analysis, we focused on the JUST released 2016 data, specifically the 2016 Crime In The United States Report. We will update the results when data becomes available for 2017 in October 2018.

So what criteria did we use? Have a look:

  • Violent Crimes Per Capita
  • Property Crimes Per Capita

In order to make the analysis as apples to apples as possible, we only considered cities over 5,000 in population. That left us with 66 cities in New Hampshire.

We then ranked each city from 1 to 66 for the two criteria with a #1 ranking being the most dangerous for the particular criteria.

Next, we averaged the two rankings into one “Dangerous Index”.

Finally, we ranked every city on the “Dangerous Index” with the lowest index being the most dangerous in New Hampshire — Laconia. Read on for a detailed look at the 10 most dangerous cities in New Hampshire.

2. Rochester

Rochester, New Hampshire

Source: Wikipedia

Population: 30,096

Property Crimes Per 100k: 3,332
A city on the eastern edge of the state, Rochester is the 2nd most dangerous city in New Hampshire overall.

Source: Wikipedia

Rank Last Year: 6 (Up 3)
Violent Crimes Per 100k: 289

The 10 sq. mile Somersworth saw a total of 359 property crimes in 2016, which calculates out to a 1 in 32.7 chance of being a victim of theft.

Somersworth ranked 5th for violent crime.

Source: Wikipedia

Population: 110,353
Rank Last Year: 2 (Down 2)

Located in south-central New Hampshire, Manchester is the largest city in the state, as well as the largest city in northern New England.

While the city has been named one of the most affordable in the region by several sources, its status as the 4th most violent city in the state might mar that fact.

Between 2014-16, violent crime went up, leaving residents with a 1 in 148 chance of being the victim of violence in 2016; that’s considerably higher than most places on the list.

5. Lebanon

Lebanon, New Hampshire

Source: Wikipedia

Population: 13,668
Rank Last Year: 5 (No Change)
Violent Crimes Per 100k: 278
Property Crimes Per 100k: 2,985
From 2014-16, Lebanon experienced an enormous jump in instances of violent crime, leaving residents with a 1 in 359 chance of being the victim of violence in 2016.

Property crime also went up during this period, meaning that, if trends continue, Lebanon will climb this list in no time.

6. Plymouth

Violent Crimes Per 100k: 451
Property Crimes Per 100k: 2,635

7. Keene

Keene, New Hampshire

Source: Wikipedia

Population: 23,244
Rank Last Year: 4 (Down 3)

Instances of property crime went up between 2014-16, with 2016’s rate being 1 in 34.4.

Violent crime also went up during this time period to 15th worst overall, which didn’t quite get Keene into the top ten most violent cities in the state.

8. Belmont


Population: 7,315
Rank Last Year: 8 (No Change)
Violent Crimes Per 100k: 287
Property Crimes Per 100k: 1,886
Belmont is the least populated city on this list, as well as the least violent.

Located in the southeastern corner of the state, on the Atlantic coast, Seabrook ranks 9th for its danger.

In 2011, Seabrook wouldn’t have made this list, but a whopping increase in violent crime between 2014-16 changed that.

10. Claremont

Source: Wikipedia

Violent Crimes Per 100k: 224

  1. The only reason my hometown of laconia even registers on this list is the fact that bike week is held here every year. Our population doubles from tourists and everyone gets drunk and stupid.

    1. The biggest reason laconia is on here is because of the drug problem, along with unemployment and lazy people on disability that dont need it. Dont blame bike when most of the crime happens the rest of the year not during bike week.
