Commonly perceived as rare, copycat crime has not been sufficiently studied. In an effort to encourage research, this research note offers a refined estimate of the proportion of offenders and at-risk individuals who report personal copycat crime histories. An analysis of 10 estimates spanning 50 years of self-reported copycat crime prevalence among just under 1,500 respondents was conducted. Collectively, the 10 study estimates indicate that about one in four respondents reported personal copycat crime histories. A random effects model indicated that prevalence estimates vary significantly across studies but effect moderators were not able to be identified. Copycat crime was indicated as a characteristic of a substantial number of offenders and at-risk youth. Copycat crime is deserving of more serious research and a number of associated research questions await attention.
