Evans Data analysts conduct extensive secondary research each year to determine the software developer population for the top 30 in the world. Sources include IMF, World Bank, CIA and many others. Data is put into a model which estimates current populations and makes projections for the next five years. This gives us the developer population data.
On top of that population data we layer selected results from our semi-annual Global Development survey to show not only overall populations but the number of developers in each country or region who are using various technologies like language, platform, etc. This makes this study unique in the industry.
We could tell you how many developers in China are using Java.
We could tell you how many developers in Brazil target mobile devices.
Evans Data recommends clients use this survey in combination with it's companion survey series; the Global Development Survey series, in order to completely understand the full scope and complexity of the developer layout worldwide. This report combined with the Global Survey Series provides the most comprehensive view of developers on a global basis.
