Is the connection between city size and amount of crime a regression or correlation type problem?
Answers
Answer:
The fact that the volume of crime is related to the size of a jurisdiction's population has been well established. The relationship between crime rate and population size, however, is less clear. Crime rate presents crime on a per capita basis, and is intended to adjust for population size so that comparisons can be made. In this article, the author first establishes the statistical relationship between crime rate and population size. Once established, he conducted an analysis of crime rates in jurisdictions of various sizes and in a variety of population-based strata using data obtained from the Uniform Crime Reports (UCR). Based on his findings, the author discusses implications for research and analysis, database management, and making jurisdictional comparisons of crime rates.

Answer:
Step-by-step explanation:
Do large cities suffer from even greater incidence of crime? According to Bettencourt, et al. (2007), the number of crime follows super-linear relationship as a function of city size. For example, if the population size increases by 100%, the incidence of crime may increase by 120%. We analyzed a total of 11 types of crimes during 1995 to 2010 for about 250 cities exceeding the residents of 100,000 or more in the United States. We found that the relationship between the number of crime counts and size of cities have followed super-linear power function without exception. We also found that the values of scale exponents display time-invariant pattern during the 16-year period.
