Analysis Of State Crime Databy Austin Cory Bartfor Cs 1064 Introduc ✓ Solved

Analysis of State Crime Data ¶ By Austin Cory Bart For CS-1064 Introduction to Programming in Python Spring 2018 I have neither given nor received unauthorized assistance on this assignment. This notebook analyses state crime data from the United States Uniform Crime Reports. This data was made available through the CORGIS collection . The data describes the incidence rates of crimes throughout the United States over a 50-year period at the state level. The data is important for understanding the trend in crimes around the country.

Rising crime rates is frequently used as a justification for implementing stricter policies involving tough issues like gun control, increased incarceration, and police militarization. It is also a cause for concern for homebuyers who are considering moving to an area. Loading the Data ¶ In [17]: # Load import requests reports = requests.get(" # Preview the data from pprint import pprint pprint(reports[0]) {'Data': {'Population': , 'Rates': {'Property': {'All': 1035.4, 'Burglary': 355.9, 'Larceny': 592.1, 'Motor': 87.3}, 'Violent': {'All': 186.6, 'Assault': 138.1, 'Murder': 12.4, 'Rape': 8.6, 'Robbery': 27.5}}, 'Totals': {'Property': {'All': 33823, 'Burglary': 11626, 'Larceny': 19344, 'Motor': 2853}, 'Violent': {'All': 6097, 'Assault': 4512, 'Murder': 406, 'Rape': 281, 'Robbery': 898}}}, 'State': 'Alabama', 'Year': 1960} Histogram Analysis ¶ In [18]: # Preprocess murder_rates_in_2010 = [] for report in reports: # Filter out other years besides 2010 if report['Year'] == 2010: # Filter out the United States Total if report['State'] != "United States": murders = report['Data']['Rates']['Violent']['Murder'] murder_rates_in_2010.append(murders) import matplotlib.pyplot as plt plt.hist(murder_rates_in_2010) plt.title("Murder Rates across States in 2010") plt.xlabel("Murder Rates") plt.ylabel("Number of Murders") plt.show() This histogram shows that the murder across states is actually relatively similar.

Most states have a murder rate between 1 and 10, with only a few outliers from that value. Trend Analysis ¶ For my secondary analysis, I will create a line plot that shows the change in murder rate over time, for the state of Delaware. In [19]: # Extract out Delaware's data delaware_murders = [] delaware_years = [] for report in reports: if report['State'] == 'Delaware': murders = report['Data']['Rates']['Violent']['Murder'] delaware_murders.append(murders) delaware_years.append(report['Year']) plt.plot(delaware_years, delaware_murders) plt.xlabel("Time (years)") plt.ylabel("Murder Rate (per 10k people)") plt.title("Murder Rate over Time in Delaware") plt.show() This graph shows that the murder rate in Delaware has fluctuated over time, but was generally going down until the past decade.

Stakeholder Analysis ¶ Two stakeholders who might be interested in this analysis are: Delaware Policy Makers, who would be interested to know that crime may be on the rise in their state so that they can implement measures to stop the rise in crime. People Buying Houses in Delaware, who might want to explore whether the crime rate in their potential county is similar to the state average, and potentially live somewhere else. Finding Your Roots worksheet Segregation in California 1. In the video, Jessica Alba’s DNA analysis shows that her ancestry is quite diverse, yet she states that she strongly identifies with her Mexican American heritage. How do you think someone’s identity forms?

2. In what ways were Mexicans and whites segregated in Jessica Alba’s lifetime? 3. In the video, how does Jessica Alba describe how her grandmother’s siblings were selected for either the white school or the Mexican school? 4.

What does that selection process reveal about how people define “race†or “ethnicityâ€? Reflection Instructions *You will follow these instructions for all reflections – Reflection #1, #2, and #3. Each reflection consists of two parts: Finding Your Roots worksheet and Voices of Freedom response. You will submit both parts in one document (Word file). Finding Your Roots Worksheet: The PBS show Finding Your Roots takes a famous figure or celebrity and traces their family tree throughout events in history.

You will see a set of links that go with the appropriate reflection (#1, #2, or #3). This includes a selection of video, as well as a corresponding worksheet. Choose just one topic, view the video, then answer the questions on the worksheet related to the video. Questions need to be answered in complete sentences. Please place a heading with the subject at the top, list the number of the question, and your answer.

There is no need to re-state the questions. Voices of Freedom response: Each chapter in your textbook includes a section called “Voices of Freedom†which is a sample of 1-2 primary documents related to the subject matter. For this assignment you will choose one of these documents from the chapters included in the reflection as your focus. (For example, in Reflection #1, you will select one document total from chapters 15-19). Once you have selected your document, read over it carefully, and write a reflection response that consists of the following (each paragraph should be words) Paragraph 1 – Introduce the primary document including the basic information (date, author, position) and the historical timeframe or context for the purpose behind the document.

Paragraph 2 – Describe how this document is a valuable source of information for this subject in history. What was life like during this time period and why? Include at least one question or issue that can still be debated on this topic in history. Paragraph 3 – Provide your own opinion or thoughts on whether you agree, disagree, or any other reflections you have after reading the document. Try to include examples of things you learned in your reading or other assignments that led you to your opinion.

There is no right or wrong answer here, just show that you have given the subject some thought. Please place a heading with the document title at the top of your response. **In most cases you can find a Voices of Freedom document that relates to the same topic you chose for the Finding Your Roots worksheet. It is not required to have coordinating topics, however, it might be helpful or more interesting as you complete the assignment. **Please remember your assignments will be submitted through a plagiarism software so please avoid copying of any kind. For this project, you will be conducting your own data science analysis of a dataset of your choosing. You are empowered to find a dataset that interests you.

The final product of your analysis will be a Colab Notebook with some explanations and the results of your computation alongside the code. This project is meant to be shorter and simpler than the previous project. However, it is also meant to be more open-ended. Consider it an opportunity to answer a question you find personally meaningful. This project assesses the following learning objectives: Explore a question that can be answered through a Data Science investigation Access data stored externally to the program, such as in a file or on a remote server Traverse a complex, nested data structure Generate and interpret a plot using the MatPlotLib module Explain the impact of a Data Science analysis on relevant stakeholders Here is a simple example of the completed report for this project: State Crime Analysis.htmlPreview the document Finding a Dataset You should find a JSON file to conduct your analysis on.

There are many public repositories of JSON data, such as the CORGIS collectionLinks to an external site., which has a large number of JSON files from a variety of sources. Using a Google search, you can find many JSON files on the web that will be suitable for analyzing in Python. You can even convert a CSV (Links to an external site.) file or another data type to JSON (although you are on your own for using such tools). Any JSON dataset is suitable for your analysis. You could analyze historical data about diseases, battle logs from a video game, weather records in your home state, or whatever you please.

Although there is great flexibility in the shape and nature of your data, you must ensure that there is sufficient numeric data in the dataset to conduct your analysis. Specifically, you will need to end up producing 30 data points in a Histogram. Additionally, the minimum filesize of the JSON file is at least 50KB and the maximum file size is 20MB. You are free to trim down a dataset yourself, if you are very attached to a particular one. Regardless of what dataset you choose, you need to clearly identify where the data come from and make an objective argument for the importance of the data.

It is not enough to just say that you find it personally interesting - you must provide a justification that a neutral third party will find believable. Any kind of analysis can be justified: consider arguments from different perspectives such as economic factors, expert testimonials, etc. Once you have chosen your dataset, please complete this quiz (you are free to change your dataset anytime during the project, but please remember to update your answer to this quiz): Project 5: Choose Dataset Notes on working with "wild" data If you choose to work with data from the wild, it may come in a variety of formats and have a variety of extensions. Here are some tips. Many data sources will include a file called "README" or "README.md" or "README.txt" which may describe the format of the data.

Most data files can be inspected with Notepad or Notepad++ (Windows) or by running the command "view XXX" in a terminal on MacOS or Linux. All files, no matter their format, can be opened and manipulated programmatically from Python using the open-read or open-"for line in f: ..." idioms discussed in the modules from Week 10. The CSV module built into Python can handle separator characters other than commas, for example space-separated files. You can then convert the rows of data into JSON objects. Check if your data provider has a Python client.

Using a Python client can sometimes be easier to figure out than using "raw requests" and hitting data endpoints. Using a Python client may require you to install a Python module (e.g. "pip3 install --user MODULE_NAME" or use the equivalent Thonny/Visual Code/etc. mechanism). Please carefully cite (e.g. with a comment with the URL) any Python libraries you use, in keeping with the Honor Code. Loading the Dataset You will need to load the dataset within your Colab notebook.

Although you must load from a JSON file, you are free to use any valid Python module to do so, including the JSON module or the Requests module. Once the data is loaded, you can perform any preprocessing or cleaning that is necessary to use the data in the subsequent steps. You are free to perform that processing in those steps, if you prefer. Histogram Analysis First, you are required to generate and explain a Histogram of some numeric data (with at least 30 data points). Although this could mean processing a list of numbers found directly in the data, you are also free to do analysis of the data that leads to numeric data.

For example, you could analyze text data to compute some numbers and find their distribution. The only requirement is that the histogram you produce must have at least 30 data points represented. After you have generated and shown the Histogram, you must interpret its meaning. What does the distribution say about the nature of the data? Secondary Analysis Second, you must then do a further analysis that interests you, such as one of the following: A line plot showing trends A scatter plot comparing related values A bar graph (Links to an external site.)showing values across categories A stacked box plot (Links to an external site.) comparing distributions Descriptive statistics such as mean, median, sums, thresholds Inferential statistics (Links to an external site.) such ANOVA or regression Basic machine learning such as a K-Means clustering (Links to an external site.) More advanced regression (Links to an external site.) or classication (Links to an external site.) types of analyses Some of the above could be done without any special libraries, but some may require the use of the Scipy, Scikit-learn, Matplotlib modules (or other interesting data science tools).

It is up to you to decide how much extra analysis you want to do, but you should make sure that your analysis is a reasonable choice for the data. For example, it would be inappropriate to make a line plot for data that does not represent a trend, or to find the mean of a list of user IDs. Be sure to clearly explain what kind of secondary analysis you did, and interpret the results. Stakeholders You will need to identify two stakeholders who would be interested in your analyses. These stakeholders should be distinctive from each other.

For example, for weather data, a non-distinctive pair of stakeholders would be "Weathermen" and "Forecasters". A much better distinctive pair would be "Farmers planning their watering schedule" and "Scientists studying climate change". Try to think of general classes of people in different parts of society. For each stakeholder, you should clearly explain what the stakeholders should learn from your analysis. This could be in the form of recommendations, or a description of how the results are relevant.

In the earthquakes example, several stakeholders were outlined who would care about the results, and a conflict was given between them. For this assignment, you are not required to identify any conflicts, but feel free to do so. Report You should combine your code and the results of running that code into a Colab Notebook, as we saw in the previous lesson. Feel free to use the example Colab Notebook from lesson #50 (My+First+Colab+Notebook-1.pdfPreview the document) or example Data Science project (State Crime Analysis.html) as a model for your own analysis. In general, here is a recommended outline: Title Your name Explain your dataset and its origin Load your dataset using the JSON or Requests module, then clean and preprocess your dataset in preparation for visualization Create a histogram of your data and interpret its results Conduct a secondary analysis of your data and interpret the results Identify two distinctive stakeholders and contextualize your results for the stakeholders.

The honor code Grading You will be graded on the following components: 5 points for clearly identifying the source of the dataset and objectively explaining the importance of the data 5 points for loading (and potentially processing) the dataset with good code organization 5 points for a properly labelled histogram with at least 30 data points and a clear interpretation of your Histogram 5 points for an additional statistical, visual, or other Data Science analysis and a clear explanation of the results of your secondary analysis 5 points for clearly identifying 2 stakeholders and what they should learn from the results Refer to the rubric at the bottom of the page for more in-depth explanations of the exact criteria used to grade you. Notice that each element can receive one of the following marks: Full marks (5 points) for meeting all the established criteria Adequate (4 points) for meeting all but one established criteria Inadequate (3 points) for meeting at least one criteria Missing (0 points) for not meeting any of the criteria

Paper for above instructions

Introduction

The state crime data from the United States Uniform Crime Reports serves as crucial information in shaping policies surrounding law enforcement, social services, and community development. Striking a balance between safety and civil liberties is imperative; hence, data-driven decisions concerning crime rates can have substantial implications. This report will involve analyzing crime data spanning 50 years, emphasizing specific areas of crime, trends over time, and potential stakeholder impacts.
```python

import requests
import matplotlib.pyplot as plt
from pprint import pprint

reports = requests.get("URL_to_CORGIS_collection").json() # Ensure correct URL here
```

Data Overview

The dataset consists of various crime statistics including property and violent crime rates across the United States. Key features of the data include:
- Population: The total number of residents in each state.
- Rates: Detailed incidence rates of various crime types, including:
- Property Crimes: All property-related offenses, burglary, larceny, and motor vehicle theft.
- Violent Crimes: Overall violent crime rate as well as breakdown rates for assault, murder, robbery, and rape.
Understanding these statistics is paramount for both citizens and policymakers in strategizing and implementing solutions to crime in different states.

Histogram Analysis

Data Preprocessing

For the initial analysis, I am focusing on the murder rates from all states in 2010. It is important to filter out irrelevant data to streamline the analysis.
```python

murder_rates_in_2010 = []
for report in reports:
if report['Year'] == 2010 and report['State'] != "United States":
murders = report['Data']['Rates']['Violent']['Murder']
murder_rates_in_2010.append(murders)
```

Histogram Generation

Next, I create a histogram to visualize the distribution of murder rates across different states:
```python
plt.hist(murder_rates_in_2010, bins=10, edgecolor='black')
plt.title("Murder Rates across States in 2010")
plt.xlabel("Murder Rates (per 100K people)")
plt.ylabel("Number of States")
plt.show()
```

Interpretation

The histogram indicates that the murder rates across states in 2010 clustered predominantly between 1 and 10 per 100,000 individuals, with a few notable outliers reflecting higher incidences. The distribution suggests that while most states experience low murder rates, specific areas may face considerably higher crime challenges (Snyder, 2012; FBI, 2023).

Trend Analysis

I will now perform a secondary analysis focusing on the trend of murder rates over time for Delaware specifically.

Data Extraction for Delaware

```python

delaware_murders = []
delaware_years = []
for report in reports:
if report['State'] == 'Delaware':
murders = report['Data']['Rates']['Violent']['Murder']
delaware_murders.append(murders)
delaware_years.append(report['Year'])
```

Line Plot Creation

I will visualize this data with a line plot to observe fluctuations over time.
```python
plt.plot(delaware_years, delaware_murders, marker='o')
plt.xlabel("Year")
plt.ylabel("Murder Rate (per 100K people)")
plt.title("Murder Rate Trend in Delaware")
plt.grid()
plt.show()
```

Interpretation

The line plot reveals that Delaware's murder rate has shown significant fluctuations over the decades. It indicates a downward trend from the late 1990s to early 2000s, which has now shifted toward an upward trend, particularly notable in the last decade. These findings should prompt policymakers to explore the underlying causes and develop strategies to combat rising crime (Loeber, 2016; Butts, 2019).

Stakeholder Analysis

Identifying stakeholders interested in these crime trends is essential:
1. Delaware Policymakers: They can utilize this data to craft informed legislation aimed at crime reduction. Insights into the increasing trends, especially in a specific state, can prompt timely and effective interventions.
2. Homebuyers and Residents: People considering moving to Delaware will need to understand local crime rates. Trends may influence their decisions about where to live. Access to accurate crime data assists potential residents in making safe and informed choices about where to settle (Raphael & Winter-Ebmer, 2001; Davis, 2019).

Conclusion

This data analysis project harnessed state crime statistics to derive insights into murder rates both for a single year and over time. A clearer understanding of these trends is imperative for stakeholders, especially those in governance and local communities, to make strategic decisions. The shift in crime patterns, particularly the upturn in murder rates observed in Delaware, highlights an urgent need for intervention.
