Infractions follow activity, not residents
The records look more like a map of businesses than of residents.
The city in use · What kind of city is at work when each offense occurs?
Nine years of administrative offenses recorded in San Pedro Garza García: their geography resembles the city in use more than the city where people live, and it changes with the hour, where people come from and enforcement operations.

The problem
The city doesn’t change only from one neighborhood to the next. It changes with who is there, what activity takes place, what time it is and how the government steps in.
Does the geography of Civic Justice look more like the city that lives in San Pedro, or the city that uses San Pedro?
What we found
Incidents follow activity, not population
By AGEB, records are more closely related to economic activity (correlation of 0.70) than to resident population (0.50).
Fights are concentrated near bars
29% of fights from 2015 to 2019 occurred within 250 m of a bar or nightclub, versus 9% of other offenses; at night, 37%. From 2020 to 2023, 60% of nighttime fights involving non-residents.
Records depend on when enforcement operations take place
On days with sobriety checkpoints, an average of 3.72 drunk-driving arrests are recorded, versus 0.67 on days without them.
Where incidents are most frequent, there are no service requests
Nighttime mobility corridors concentrate incidents but not service requests: AGEB 0399 totals 608 incidents, 83% at night, and no street lighting requests.
Almost no one requests services in those corridors
Street Cleaning receives 14 requests per thousand residents there, the lowest figure of any territory type.

What we recommend
Inspect street lighting and cleaning in the nighttime corridors proactively, without waiting for reports, starting with AGEBs 0399, 0098 and 0079.
Safety and services should be coordinated around the city used at night, not the one that files reports by day.
