There’s a power law

If we count up how many posts each user makes, and then plot a graph with that data, it looks like this:

Number of posts per user

This distribution of number of posts per user is interesting and appears to show a power law. This is similar to the Pareto principle, which is also known as the 80/20 rule.

The Pareto Principle

“Pareto showed that approximately 80% of the land in Italy was owned by 20% of the population; Pareto developed the principle by observing that about 20% of the peapods in his garden contained 80% of the peas.”

Power laws elsewhere

Here are some more things which show power law distributions:

  • the sizes of craters on the moon and of solar flares
  • the foraging pattern of various species
  • the sizes of activity patterns of neuronal populations
  • the frequencies of words in most languages
  • frequencies of family names
  • the species richness in clades of organisms
  • the sizes of power outages
  • criminal charges per convict
