In the United States, media has a great deal of influence on the people it has contact with. Over time the media has gained both positive and negative report regarding their intuitions. As such, for many years sources such as the Wall Street Journal, Fox News, NBC News, and USA Today all have their own takes on the safest and least safe cities in the United States. The research for today's discussion focuses on the question: “How faithful is the information the media is giving us?”After receiving an FBI Crime Dataset with crime from 1979 to 2014, Blake used data mining analysis to determine some crime patterns in the data. After viewing sources regarding the top 10 best cities and top 10 worst cities , the goal involved confirming if the pattern findings were correct. After Blake applied various data mining techniques including the K-means algorithm on the data set, Figure 3 shows the analysis of a high dimensional crime pattern being found when reduced to a geometrically interpretable dimension. With a confirmed algorithm showing results that make sense, the analysis of how the best cities and worst cities crime patterns are grouped over time.
The following tables show some of the cities that the algorithms are dealing with and how they rank before they are applied into the algorithm over time. As stated in the article titled Best places to live and 50 worst cities to live, the following tables show the best and worst 10 cities to live in the U.S:
|Best Cities||State Code|
|WEST DES MOINES||14|
|PARSIPPANY TROY HILLS||29|
|Worst Cities||State Code|
The analysis has shown that the best cities and the worst cities have a significant amount of overlap when clustered together. An interesting study would be to determine how much the media has displayed this information in the past, or at the very least, how often the media has taken cities off of the limelight of being best and actually grouped them into the worst. With a global understanding that crime in general has gone down, we don't have good statistics to determine that certain cities crime patterns have gotten better or worse. An example of a good situation would be if a city's population goes up while crime goes down, and this certainly can be the case for many cities accross the globe, but is not always the case. As we can see from the previous analysis, some smaller and general more well known safe cities can find themselves with quite malicious crime patterns rivaling some of the worst cities. With a better understanding of how cities are grouped over time, the only question left standing is how safe are the U.S's safest cities?
