The following examples are sometimes seen as approximately Pareto-distributed:* The sizes of human settlements (few cities, many hamlets/villages)* File size distribution of Internet traffic which uses the TCP protocol (many smaller files, few larger ones)* Hard disk drive error rates* Clusters of Bose–Einstein condensate near absolute zero* The values of oil reserves in oil fields (a few large fields, many small fields)* The length distribution in jobs assigned supercomputers (a few large ones, many small ones)* The standardized price returns on individual stocks* Sizes of sand particles* Sizes of meteorites* Numbers of species per genus (There is subjectivity involved: The tendency to divide a genus into two or more increases with the number of species in it)* Areas burnt in forest fires* Severity of large casualty losses for certain lines of business such as general liability, commercial auto, and workers compensation.
* THESE TWO SEEM TO BELONG UNDER Zipf's law RATHER THAN THE PARETO DISTRIBUTION:** Frequencies of words in longer texts (a few words are used often, lots of words are used infrequently)** Frequencies of given names* The sizes of human settlements (few cities, many hamlets/villages)* File size distribution of Internet traffic which uses the TCP protocol (many smaller files, few larger ones)* Hard disk drive error rates* Clusters of Bose–Einstein condensate near absolute zero* The values of oil reserves in oil fields (a few large fields, many small fields)* The length distribution in jobs assigned supercomputers (a few large ones, many small ones)* The standardized price returns on individual stocks* Sizes of sand particles* Sizes of meteorites* Numbers of species per genus (There is subjectivity involved: The tendency to divide a genus into two or more increases with the number of species in it)* Areas burnt in forest fires* Severity of large casualty losses for certain lines of business such as general liability, commercial auto, and workers compensation.
