size of XQuery developer community

[Ken North]

It's easier to compare how much is written for the XQuery web audience versus some well-known languages. 
Google reports:

Java                  275 million pages, but that's all references to Java (coffee, place and language)
C#                      47.6 million
Visual Basic        31.4 million 
COBOL                 6.4 million pages
XQuery                  1.14 million pages

There is not a direct correlation with developer community size but web searches are an indication of interest in a language. The trend for COBOL is a declining number of searches. For XQuery, it's been relatively stable for five years. In terms of news references, XQuery is also relatively stable.

Other facts on interest:

The top six languages (in order) for XQuery searches were Korean, Czech, English, Russian, Japanese and Chinese.

Bangalore, San Jose, Chennai, Mumbai, Prague and San Francisco, in that order, are the top cities for XQuery searches. 

India, Czech Republic, South Korea, Russian Federation, Singapore and Switzerland are the top regions for XQuery searches.
