How does that work? Im not a stat person.

There are a number of normalization algorithms. Easiest would be to just divide by the area’s population count. That gives you the relative number of bigfoot sightings or fursuits per capita, removing any skews introduced by varyin population size.

Say you have two areas:

Area 1: 100000 people, 1000 fursuits, 500 bigfoot sightings Area 2: 1000 people, 10 fursuits, 5 bigfoot sightings

Without knowing the population size, it looks like more fursuits means more bigfoot sightings. But if we divide by the population size, we get 0.01 fursuits and 0.005 bigfoot sightings per person in both areas.

Hope that helps. ^^

Simple normalization does amplify signals in low density areas. If a person in a tiny town of 100 reports a bigfoot sighting and another person in an area with 10,000 population also reports a sighting, then with simple normalization the map would show the area with 100 people having 100 times as many big foot sightings per capita as the area with the population of 10k. Someone casually reading the map would erroneously conclude that the tiny town is a bigfoot hotspot and would in general conclude bigfoot clearly prefers rural areas where they can hide in seclusion. When the reality is that the intense signals are artifacts of the sampling/processing methods and both areas have the same number of fursuit wearers.

That’s the point. To make the low-population area more intense. Because relative to the population density, there were 100 times as many sightings. Or what am I missing.
