About this Report

Programming languages sit at the heart of the software development ecosystem. These languages do more than provide syntax for logic; they define the boundaries of developer ecosystems, dictate the availability of talent, and determine the long-term viability of platform integrations. For product executives and engineering leaders, monitoring the ebb and flow of these communities is a strategic necessity. Selecting which languages to prioritise for SDKs, APIs, and documentation is a high-stakes decision that directly impacts a platform’s friction, reach, and eventual market share.

Beyond technical utility, languages are a primary source of professional identity and a frequent catalyst for industry-wide debate. For toolmakers and vendors, staying synchronised with these shifting preferences is essential to maintaining credibility and fostering deep, sustained engagement with the people building the future.

However, quantifying these communities with precision is a complex undertaking. Our methodology relies on the synthesis of two robust data pillars:
Global Population Modelling: Our proprietary, independent estimate of the total software developer population, a metric we have refined and tracked for nearly a decade.

The Developer Nation Survey: Our biannual, large-scale research programme that captures the pulse of tens of thousands of practitioners worldwide.
