概要	Capture-recapture, known in criminology and public health as multiple systems estimation, infers the size of a hidden population — undocumented homicide victims, trafficking victims, problem drug users, undetected offenders — that no single source counts completely. By examining how much two or more incomplete lists overlap, it estimates how many cases were missed by all of them: the 'dark figure' of crime. Borrowed from wildlife ecology, the method was synthesized for human populations by the International Working Group in 1995 and brought to criminal-justice policy by Bird and King.	The crime concentration index quantifies how unevenly crime is distributed across micro-geographic places such as street segments or addresses. Building on Sherman, Gartin, and Buerger's 1989 discovery that a small fraction of addresses produces most calls for police service, and formalized in Weisburd's 2015 'law of crime concentration', it expresses the share of all crime accounted for by the most crime-prone places.
