How Numbeo’s Crime Index works
The Crime Index estimates the overall level of crime in a city (or country). Values are categorized as follows:
- Very Low: 20 and below
- Low: 20.01-40
- Moderate: 40.01-60
- High: 60.01-80
- Very High: above 80
The Crime Index takes into account survey responses about:
- General perception of crime levels
- Perceived safety during daylight and nighttime
- Concerns about specific crimes (mugging, robbery, car theft, physical attacks, public harassment, and bias-motivated incidents)
- Property crime severity (burglary, theft, vandalism)
- Violent crime severity (assault, homicide, sexual offenses)
