How many programmers in Europe?

My name is Stas, for the further development of our project, we want to gather information about:
1) the size of the IT markets in some countries (below), that is, the number of developers in each location for 2016
2) what is the average salary of developers, for example Java 3-4 years experience

Unfortunately, this information is so fragmented that you need to spend a lot of time on her collection, so I decided to ask a question, maybe someone already asked this before me. Well, maybe it will be useful not only me.

- Romania
- Serbia
- Macedonia
- Moldova
- Poland
- Latvia
- Czech Republic
- Hungary
- Slovakia
- Bulgaria

If you have information how the number of programmers in the past year, left each country that will be just fine.
PS All the rays of goodness!
