Gun Violence in The United States - Research Limitations

Research Limitations

In the United States, research into firearms and violent crime is fraught with difficulties, associated with limited data on gun ownership and use, firearms markets, and aggregation of crime data. Research studies into gun violence have primarily taken one of two approaches: case-control studies and social ecology. Gun ownership is usually determined through surveys, proxy variables, and sometimes with production and import figures. In statistical analysis of homicides and other types of crime which are rare events, these data tend to have poisson distributions, which also presents methodological challenges to researchers. With data aggregation, it is difficult to make inferences about individual behavior. This problem, known as ecological fallacy, is not always handled properly by researchers, leading some to jump to conclusions that their data do not necessarily support.
