The type of social scientist who would research "where does the most crime happen in the world" is typically a criminologist or a sociologist specializing in crime and deviance. These social scientists study the causes, patterns, and consequences of crime in society.

To answer such a question, a criminologist or sociologist would typically employ several research methods:

1. Quantitative Analysis: They would collect and analyze statistical data on crime rates and incidents from various sources such as crime reports, law enforcement agencies, and international organizations like the United Nations Office on Drugs and Crime (UNODC). They may use statistical techniques to identify and compare crime rates across different countries or regions.

2. Comparative Analysis: They would conduct comparative studies to examine crime patterns and factors that contribute to crime in different parts of the world. They may analyze various social, economic, demographic, and cultural factors that influence crime rates, such as poverty, inequality, urbanization, cultural norms, and law enforcement strategies.

3. Case Studies: They may also study specific countries or regions that are known for high crime rates to understand the underlying factors in detail. This can involve qualitative research methods like interviews, observations, and analysis of documents and reports to gain insights into the socio-economic, political, and cultural contexts that contribute to crime.

4. Literature Review: They would review existing research and academic literature on crime rates worldwide to identify trends, theories, and methodologies that have been used to study crime patterns. This helps to build upon previous knowledge and provide a comprehensive understanding of where crime happens globally.

Overall, the research conducted by criminologists and sociologists helps policymakers, law enforcement agencies, and communities to develop crime prevention strategies and interventions tailored to specific contexts.
