Map of Usage of IUPAC and IUBMB Nomenclature Database

See below for Europe enlarged.

Key
Red = > 730 hits per million population.
Orange = 261-730 hits per million population.
Yellow = 93-261 hits per million population.
Green = 25-93 hits per million population.
Blue = 4.9-25 hits per million population.
Violet = < 4.9 hits per million population.

This IUPAC/IUBMB Nomenclature Site now keeps a log of usage statistics composed of the numerical IP address of each computer which logs on in a 24 hour period. The total from 1996 is 234 countries from nearly 13000000 records. From this data for 2010 and 2011 (over 1900000 records) an analysis of the IP addresses by geoiplookup identifies the country of origin of over 88% of IP addressses. The data was then normalised by dividing the number of records for each country by the population (in millions) and sorting into rank order. The list was divided into six hexyls which were plotted. Red = top hexyl more than 730 records per million population; Orange = 261-730; Yellow = 93-261; Green = 25-93; Blue = 4.9-25; and Violet = less than 4.9. Uncoloured countries have not been recorded by this database.

From February 1996 to October 2009 the analysis was based of the indicated country code (with about 22% numerical and 20% ending in .net excluded). This data indicated 226 countries from nearly 10700000 records which have been separately plotted.

Cartographic help from Ed Oliver is gratefully acknowledged.

The usage of each document is also logged. See the summary of statistics for 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010 and 2011. A summary of this data from 1996-2011 is also available. Also data for each country for 1996 to 2011. Any additional countries are listed in the country data with zero users for 1996 to 2009.

Since the above data was plotted there has been one additional country making a total of 234 countries based on nearly 13000000 records. In early November 2009 the log country analysis changed from DNS client to numerical IP addresses.
