I did get same for my region. But the question is: do these figures show the real-world usage or rather a resource lag of aging languages--e.g. you have more PHP jobs than Ruby because PHP devs moved to other languages and there are still tons of legacy systems to maintain. There was also an interesting article (I forgot the author, Spolsky?), who said that there's a reason why resources for aging languages are more expensive than others => The developers have more opportunity costs when developing for aging languages.

Don't get me wrong: Java, C#, C++ are maybe not aging but their user base isn't growing anymore or not with the same strong growth rate like newer languages
