I’m really struggling with the all blue key. The different shades are just too close together.

Is this better?

I think there is still a similar issue. not to say these maps you made aren't good. thank you so much for them, OP!

I also have some trouble differentiating. it would look a lot uglier, but maybe making each color entirely different would help, but then you lose the benefit of being able to look at the map as a whole and seeing clusters of counties/ cities with crime

/u/potkea - It's the gradient.... There are too many steps with colors that are too similar. If you poke around /r/dataisbeautiful for a period of time you'll see some constructive feedback in and around that area.

Ok. Thank you.

Hey potkea! Id potentially make the data into fewer cuts, which would eliminate the number of shades & simplify this overall…maybe 250/500/750/+.

What you’re really drawing attention to is outliers, and they’ll remain as such even with fewer cuts. You can also put the “incidents per 100K” somewhere ONCE - no need for it written out each time. With newfound space (or maybe even without), blow the map up larger, and maybe add a few labels somehow, calling out major cities (small, potentially unnecessary idea tbh), but could be helpful to orient.

The point of the map isn’t to see and match individual colors it’s to see trends across the state.

tstop22 t1_j265xk4 wrote

Maybe, but I think it’s a combination of things that are confusing my eye:

  • There are probably too many different buckets, what happens if you cut the number in half? Do you lose relevant data for your story?
  • The legend boxes of color are much bigger than the states that are colored. This makes it really hard to evaluate color density by eye.
  • “No data” can’t be white on a chart like this or you are biasing the story. It should probably be a different palette completely (yellow?) if you are being more neutral.

What story you are trying to tell should dictate your choices.

Interesting plot, btw. Love that you are bringing original content to the sub.

This is a re-upload based on the constructive criticism you /r/massachusetts users gave me. The original thread is archived here

I'm from Michigan, I just was teaching myself QGIS and decided that making this map would be interesting.

I used the FBI's crime data explorer to gather info on the number of violent crime incidents from reporting municipalities, divide that by the estimated population, and multiply that number by 100,000 to get the violent crime rate. For example: Boston had a total of 4,354 reported violent crimes in 2020 and an estimated population of 697,323, so (4,354/697,323) x 100,000 = a violent crime rate of 624.38 incidents per 100k.

Overall, the Commonwealth had 308.8 incidents of violent crime per every 100k residents, making it the least safe state in New England but safer than many other states and lower than the Nationwide rate of 398.5 incidents per 100k.

And since people were asking about this: Not reporting just means that the data isn't reported to the FBI.

I can always find Holyoke because it's flipping the bird to the rest of Western Mass

Doesn’t feel dark blue dangerous does it?

Balsac_is_Daddy t1_j25ksfa wrote

I cannot speak for anyone else in Holyoke, but my neighborhood feels safe. Its absolutely not perfect, this Paper City. There absolutely is crime, people have been killed, but Id say the average person wouldn't have any problems. Most of the folks I know in Holyoke chose to move here, chose to buy properties here, chose to invest time and money into this community. And we throw the best goddamn St. Patrick's Day party. ☘️

I haven’t had any issues whatsoever in holyoke. Granted, I live in a more suburban area of the city though.

There are the Heights and the Flats. The Heights are older, Victorian suburbs; the Flats are the remains of the housing for the mills workers when there were any to speak of. I worked at a business in the the Holyoke Mall and it attracts a mixed bag of people. Not at all the type of town I would want to raise a family in.

Wow! Points to SE Martha's Vineyard for nearly as much violent crime per 100k as Pittsfield, Springfield and Fall River!

supercrooky t1_j256zrj wrote

Crime rates don't work right on the Vineyard, or to lesser extent the Cape.

The problem is these figures always use the number of residents as the divisor, not the number of people present, while the crime totals are all committed by all people present, not just residents. This is a good enough approximation most places, but in the case of MV the residents figure is around 1/10th the peak summertime population. So, you get the violent crimes committed by tourists and seasonal residents all added up and attributed to the year round population, inflating the figure.

You see this to some extent or another anywhere lots of people visit and fewer people live - tourist destinations, downtown business districts, shopping centers, etc.

You run into this in Western Mass as well. The college students are often counted as living at home make the population of places like Amherst look smaller than it is.

North Adams gets hit by both factors. And its small, one extra even a year is a big deal when your population is barely over 12K.

I don't know. I think it says something. Paxton has a college, is 7K people and still has really low rates.

bryanhealey t1_j250wto wrote

honest question: what constitutes a violent crime? does that include stuff like armed burglary? would also be interested in how this compares nationally and internationally.

great map, tho! love being able to easily visualize these kind of stats.

potkea OP t1_j2526ls wrote

The FBI considers violent crime to be:

  • Murder and nonnegligent manslaughter

  • Rape

  • Robbery

  • Aggravated assault

>would also be interested in how this compares nationally and internationally.

IDK abt internationally, but nationally you can compare the rates to these: https://en.wikipedia.org/wiki/List_of_U.S._states_and_territories_by_violent_crime_rate

awesome, ty!

edit: holy shit, DC!

also, definitely interesting to see the trend lines per state from year-to-year...

DernKala1975 t1_j269qe3 wrote

In defense of DC: it’s not really fair to compare DC to the states. DC shows up as dark red compared to the states on the map but in reality would be more comparable to other large cities - I know the crime rate in DC is high but IIRC there are other cities that are higher.

96ToyotaCamry t1_j253iuc wrote

Straight from the Wikipedia article that OP linked in comment: In the United States, violent crime consists of five types of criminal offenses: murder and non-negligent manslaughter, rape, robbery, aggravated assault, and gang violence

This makes Mass the 33rd state when ranked from most to least violent crimes per 100k from 2011-2020. Mass has been on a downward trend (decreasing levels of violent crime) every year.

Whole lotta people there in the summer, but they don’t count as residents, so it just looks artificially high.

Longmeadow is interesting. Just south of two of the most violent places, Springfield and Holyoke, but far lower crime rates than any of its neighbors. Geography: the west side of town is the Connecticut River, with no bridge. The north side of town is Forest Park. The only street through the park is usually closed . It's not easy to get from Springfield to Longmeadow. And Longmeadow has a good police department.
