Κολοκοτρώνη · district
Kolokotroni scores 32 out of 100 for overall safety — above-average crime, on a scale where 50 is the average for Greece. It is home to about 4,340 people at 6,745 people per km².
The score is absolute, not a ranking: 50 is the offence rate for Greece as a whole, 100 the safest end of the scale and 0 the least safe, and every doubling of the rate costs the same number of points wherever you are. Regional units are scored from Eurostat's police-recorded offence rates per 100,000 inhabitants. Greece publishes nothing finer, so municipalities and districts share out their region's measured rate by how built-up they are and by documented local reporting — treat those two levels as an estimate, not a count of reported crime.
A street-derived local area name in the municipality rather than a defined neighbourhood - Kolokotroni is one of the commonest street names in Greece, and no municipal, police or press source consulted defines a Kolokotroni district in Neapoli-Sykies with boundaries or a population. That is worth saying plainly rather than inventing a character for it. In practice it means the blocks around the street of that name: ordinary dense residential housing with ground-floor shops, like everything around it.
No documented night-time pattern specific to this name. The municipality's recorded concerns are shop break-ins and local theft rings, not street attacks.
No particular reason to seek it out or avoid it.
