Although the most dangerous cities are mostly well-known: the perennial top ten of Detroit, St. Louis, Baltimore, Memphis etc. when you get more granular the results change pretty dramatically.
While data shows that crime is actually down in the U.S. in recent years, many Americans believe that the country is becoming more violent than ever—and high-profile incidents like mobs rioting at the U.S. Capitol and the Department of Homeland Security issuing a threat bulletin
to warn of ongoing potential for domestic violence only underscore
those fears. So the timing of a new study from the risk assessment app Augurisk Now, revealing the country’s 10 most dangerous neighborhoods, couldn’t be better.
Augurisk Now—which launched last month—helps people track the
likelihood of crime and national disasters, making it a useful tool for
everyone from travelers to concerned citizens to potential homebuyers.
The way it works: Whenever you enter a dangerous block in the U.S., the
free app uses proprietary risk-scoring algorithms to alert of potential
dangers, warning users that they have entered a predicted or observed
high crime area. Similarly, the app can predict risks when it comes to
floods, earthquakes, wildfires and storms.
“Many years ago, while I was searching for a new property that would
be safe from floods or earthquakes, I was surprised no service provided
such essential information in an intuitive form,” says founder Mohamed
Mezian. “That’s where the idea for Augurisk emerged—our main mission is
to help people and businesses better prepare for the future.”
In order to zero in on the 10 most dangerous neighborhoods in the United
States, Augurisk analyzed its data and issued a report on the riskiest
places by looking at Census block groups, a statistical division of
tracts that usually contains 600 to 3,000 residents. Augurisk then
measured each Census block group by predicting violent crime occurrences
and violent crime rate (per 100,000 residents). “The data underlying
this crime analysis are taken from the predictions of our proprietary
machine learning crime prediction algorithm,” says Augurisk’s lead
scientist Simon de Bonviller. “Other contextual factors presented in
this article were adapted from the American Community Survey 2014-2018
5-Year estimates.”
Surprisingly, some of the cities in the U.S. that have recently been named most-dangerous places—like
Detroit and Memphis—didn't make this Augurisk list. According to de
Bonviller, one explanation for this relates to the resolution
considered. “We focus on block groups— i.e. neighborhoods—while such
rankings consider crime statistics in the entire city (or law
enforcement agency),” he says. “However, one risky neighborhood doesn’t
necessarily make a whole city dangerous, and vice versa.”
Another explanation: Augurisk trained a machine learning algorithm to
predict crime occurrences based on 188 predictors (including
socioeconomic, demographic, climatic and law enforcement variables,
among others). “This algorithm was trained using the exact location and
type of crimes committed in 11 U.S. cities between 2014 and 2018,
including Detroit,” says de Bonviller. “The result was used to generate
this ranking. Thus, we use predictions of the crime expected by our
algorithm given 188 predictors related to a place, not past crime—as in
the mentioned rankings—which can explain some differences.
Nevertheless, de Bonviller says that the he and team at Augurisk were
surprised by the results—especially by the high number of dangerous
neighborhoods in California. “Initially, when we were exclusively
focusing on crime rate, the most dangerous places in the U.S. were found
to be parks, airports and other busy places with low to no population.
If the population is low, then crime risk can be overestimated when
using such an indicator. Subsequently, we therefore used the number of
crimes committed as an additional criterion. Moreover, we were surprised
to notice the high occurrence of block groups located on the West Coast
in the ranking, including in Los Angeles and San Francisco.”

America. For people who are moving from one city to another, Augurisk’s public county risk assessment can provide free insights into their new county, while people acquiring a new property can use the Augurisk website to generate a free natural disaster and societal risk report, to make sure the property is not at risk.
