We recently explored how wealthy countries (those defined as high-income by the World Bank) tend to visit a different set of technologies than the rest of the world. Among the largest differences we saw was in the programming language Python. When we focus on high-income countries, the growth of Python is even larger than it might appear from tools like Stack Overflow Trends, or in other rankings that consider global software development.

Here at Stack Overflow, we’re interested in using our data to share insights about the worldwide software development community. This recent post on the distribution of mobile developers is a good example: it explored traffic to Android questions from around the world, and found that Android tended to be visited more from lower-income countries than from higher-income ones.

In a previous post, we used the Stack Overflow Trends tool to look at how technology usage in mobile development has changed over time. But we’ve often found that popular languages, platforms and technologies differ across cities and countries as well.

Last week, Adobe announced that they would stop supporting Flash by 2020. In some ways this is surprising: I still sometimes run into pages that require Flash, and you can still find a few defenders of the platform in the software development community.

On Stack Overflow, a question gets asked once, answered, and then becomes a central point of knowledge for thousands of others who read it on our site. But what about developers who don’t have the luxury of being public about their work?
