Safety is one of the most significant factors that affect people's decisions on where to live. Everyone wants to live in a peaceful city, but usually, it is not easy to make the right choice. Searching over the Internet for crime-related news that happened within a specific location is often very time-consuming, Our app will show the distribution of serious violent crime cases that happened in 68 U.S. police jurisdictions and also the changes in the number of crimes over recent 40 years in each of these 68 U.S. police jurisdictions.
We will be visualizing the dataset of serious violent crime cases that happened in 68 U.S. police jurisdictions over 40 years. This city crime dataset is contributed by Gabriel Dance, Tom Meagher, and Emily Hopkins from the Marshall Project. It contains 2829 entries. Each of the entries denotes a report of crimes that happened in a specific location in a specific year.
The column ORI is an identifier for each police jurisdiction and the column department_name is the name of the department. The column total_pop represents the number of residents living under the specific police jurisdiction.
The dataset includes information about four types of major violent crimes: homicide, rape, robbery and aggravated assault. Column violent_crime is the total number of violent crimes that happened and homs_sum, rape_sum, rob_sum and agg_ass_sum are the number of crime cases of each of the categories respectively. Column violent_per_100k is the average number of violent crimes within every 100 thousand residents in that city.
Safety is one of the biggest concerns for people who are considering to relocate/travel to a new city. It then boils down to the question "Where is safe now and would the city remain safe in the future?" The research question can be further split into the following questions:
-
Which is the safest state?
-

The total number of violent crimes in this city is increasing or decreasing over the recent decade?
