Sammanfattning	Broken windows assessment is the systematic measurement of physical and social disorder — graffiti, litter, broken windows, public drinking, loitering — tied to the hypothesis that visible disorder signals that no one is in control and thereby invites further crime. Stated by Wilson and Kelling in 1982 and put on a rigorous empirical footing by Sampson and Raudenbush's systematic social observation, it turns the metaphor of an unrepaired broken window into a quantified, reliable neighborhood scale.	Routine activity theory explains predatory crime not by the supply of motivated offenders but by the everyday structure of legal activities that brings offenders, targets, and the absence of guardians together in space and time. Proposed by Lawrence Cohen and Marcus Felson in 1979, it argues that crime rates can rise even when offender motivation is constant, because changes in how people work, shop, and spend leisure time alter the opportunities for crime.
