Map of Usage of IUPAC and IUBMB Nomenclature Database

See below for Europe enlarged.

Key
Red = > 2300 hits per million population.
Orange = 545-2300 hits per million population.
Yellow = 200-545 hits per million population.
Green = 47-200 hits per million population.
Blue = 7-47 hits per million population.
Violet = < 7 hits per million population.

This IUPAC/IUBMB Nomenclature Site keeps a log of usage statistics composed of the IP address of each computer which logs on in a 24 hour period. From this data an analysis of the IP addresses shows that 22% are numerical only, 20% end in .net but most of the rest can be assigned to the country of origin. Based on these records the follow map has been prepared. Data for Russia is based on .ru + .su; for UK .gb + .uk; and for USA .us + .com + .edu + .gov + .mil (Although this is not strictly correct it is probably close to the true figure). Based on the records from February 1996 to January 2010, with nearly 10700000 records, 226 countries were identified. The data was then normalised by dividing the number of records for each country by the population (in millions) and sorted into rank order. The list was divided into six hexyls which were plotted. Red = top hexyl more than 2300 records per million population; Orange = 2300-545; Yellow = 545-200; Green = 200-47; Blue = 47-7; and Violet = less than 7. Uncoloured countries have not been recorded by this database (although possibly concealed in the numerical only or .net IP addresses). Since November 2009 the web log has only recorded numerical IP addresses and these have been analysed using geoiplookup.

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 and 2009. A summary of this data from 1996-2009 is also available. Also data for each country for 1996 to 2010.

Due to the change in the method for identifying countries the data for 2010 represents 91% and has been plotted separately.
