A viewing tells you about the flat. It tells you nothing about the street at 11pm, or how the area compares with the one you looked at last week. SafeZone Map shows reported-incident levels for the actual neighbourhood — normalised by population, with every score citing the reports behind it.
Every area is ranked against comparable areas in the same scoring pool — a city neighbourhood against city neighbourhoods, never against countryside. The panel says which pool, and how many areas are in it.
The incidents behind a rating are listed with their dates and their sources, so you can read them yourself rather than trusting a colour.

Areas with too little reported data are shown as "insufficient data" — grey, and labelled. That is never presented as a quiet area.
It is not a safety verdict, and it is not an official crime rate. It measures the level of publicly reported incidents relative to comparable areas, which is a different thing from how safe a street is — reporting rates vary, and some areas are covered by more local news than others. Read it as one input among several, alongside visiting at different times of day and talking to people who live there.
