A decade of Minneapolis homicides, population averaged

A couple of smart people asked that I balance yesterday’s “murder moat map” for neighborhood population, so here it is:

A few notes about the math:

It’s basically a given neighborhood’s decade-long homicide count divided by population times 10,000 to get a whole-number index. For example, Kingfield had 5 homicides over the decade, in a neighborhood of 7,473 people. Times 10,000 that gives you an index of 7, rounding up.

(If you want to think of the index as a phrase, it’s “annual homicides per 100,000 people.”)

The good news, such as it is, is that the index numbers (and thus the neighborhoods) can be compared to each other. For example, Kingfield (7) has 1/13th the murder rate of Hawthorne (94).

You can see Hawthorne really stands out, with almost twice the homicide rate of any other Minneapolis neighborhood, including Jordan and East Phillips.

As noted on the index, red numbers are above the city average (index: 11), yellow are below, and green is for the neighborhoods with no homicides from December 2003 to November 2013. I tried to make the red gradient reflect the index.

There are always limitations to the data. One is that it’s only balanced by population — not accounting for workers or tourists. Downtown’s homicide index, for example, might be high given all the non-residents who work and play there.

You’ll probably want to compare it to yesterday’s “murder moat map”:
