At Stack Overflow, we’re a big fan of developer surveys. Developers win when they have open access to data about technology usage, development practices, and what employers pay. This is why we were so excited when GitHub released the results of their Open Source Survey, which looked at open source software development practices and communities.

When developers are deciding between job offers, they’ll weigh factors such as salary, growth potential, and work benefits. One important benefit for developers on the cusp of starting families will be the opportunity to take paid parental leave.

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.
