Does Temperature have an Impact on US Crime Rate?

Since 1960s, crime rates in the United states have been declining and remained stubbornly low till now. However, the FBI recently reported that crime rates have been on the uptick since 2014, despite the nation’s best efforts in curbing crime. This project attempts to explore the relationship between temperature and crime rates in US crime data. Due to the increasing effects of climate change, it is critical that we understand the societal effects of changing temperature. Panel data consisting of crime and temperature (across various cities) will be used for analysis, and a quasi-experiment will be constructed to determine causality.

They are not just pets, they are the guardian of my home

It’s about our best friends, our pets. When my brain was totally drained from causal analytics topics, my lovely dog jumped onto my lap and rubbed her tiny furry head around my arms – then I asked, what my dog has caused to my life? I have one dog and six cats. I was born with a shepherd dog in my house. Love for sure, but equally importantly, they make me feel safe and secured. In this project, we’d like to discover any tangible causal impact of having a pet such as dog and cat at home on home security, e.g. burglary occurrence. We hope by presenting our findings, it can light some sparks in people's mind on home security and human-pet relationships. After all, analytics are from our daily lives and are for our daily livings.


The causal analysis between air pollutants and daily crime rate

Though physiological effects of exposure to outdoor and ambient air pollutants on cognitive function and crime have been discussed in literature, to date, very few studies examined causal effect between these air pollutants and their potential impact on reported crime. Panel Fixed Effects and Instrumental Variable Model on aggregate daily crime data and air pollution concentrations for each location will be used to analyze the potential causal relationships between changes in outdoor air pollutant concentrations and the number of crimes reported per day.
