Their conclusions are without basis

It asks an interesting question but its methodology is wretchedly bad. From The world’s most-surveilled cities by Paul Bischoff.

According to this, Atlanta, with only 7,800 CCTVs is the tenth most surveilled city in the world. More surveilled than Singapore.

The problem is that they have the number of CCTV cameras and the nominal population and they just did a simple division. There are actually two sets of problems. The more egregious is that they have not normalized definitions of jurisdictional boundaries and therefore are not controlling for density. Some cities they are using metropolitan areas, some they are using jurisdictional areas.

In Atlanta, with some 450,000 people, there are huge swaths of countryside within the city limits and the density is comparatively low for other cities in the list. The CCTV cameras are concentrated down town and then are thinly distributed into the neighborhoods, with many neighborhoods with no cameras.

The second issue, which is an emerging one, is the degree to which government surveillance incorporates private security cameras. In Atlanta, there are probably ten or more times as many private cameras covering public property as there are government cameras. Some of them are integrated with the public surveillance, most are not.

It is an interesting question as to which cities are most surveilled but this simplistic approach does not answer the question. And without addressing their methodological flaws, their conclusions are without basis.
