The answer to how many developers are there in the world. This page is updated with the newest estimate twice per year. There are 48.4 million developers around the world Source: SlashData Developer Nation surveys | Updated: Q3 2025 How Many Developers Are There in the World? This is our most frequently asked question here at SlashData, both from professionals who need to size their addressable market or tech market trends followers. To help you, we happily share this number and update it as new data comes along. Go ahead and confidently use this number in your pitch, BoD presentation, or article. We follow a strict methodology to ensure that this is the most accurate estimate you can get. Why you can trust this developer population number You can trust this number because we rely on two key sources for our estimates: Reliable 3rd-party Data Sources – We analyze developer activity from GitHub, Stack Overflow, and employment statistics. Our own Developer Nation Survey data – Our survey has been conducted 29 times, with over 10,000 developers per wave. By calibrating external data with survey findings, we create a global developer estimate. This estimate can be segmented in many ways for instance by region and technology. Are you looking to size a particular segment? Get in touch and we will walk you through the process.

All of these are susceptible to a multiplier effect, not in the least due to multi-machine and multi-browser software testing, frequent cleaning of caches and cookies for testing, etc. SlashData estimates are exclusively based on what we consider to be direct indicators of human developer activity. At the same time, we go to great lengths to minimise the probability of major sampling biases in the following ways: 1. Having the largest, broadest and most diverse developer sample In each survey we field 10,000+ responses. By reaching out to developers afresh in every survey through dozens of independent channels, we minimise repeat sampling bias. We design a holistic sampling regime to ensure that our sample is never biased towards specific regional, vendor, or technology communities. 2. Minimized bias through weighting We use a sophisticated weighting methodology, which we have developed and evolved in-house, to correct for possible sampling biases across outreach channels, regions, development platforms, and more.

Our methodology is rigorous and airtight, ensuring our data is of the highest quality and exceeds industry standards.

You get decision context: what the data means for your roadmap, budget, or go-to-market. How reliable is the data? We run large-scale, independent, global developer research surveys with consistent methodology across waves. Our methodology is rigorous both at clearing our fraudulent (or inaccurate) data and in weighting for proper distribution and reduced margin of error.

Can this support a business case or budget proposal? Yes. Many clients use our data to: Justify entering a new developer segment Prioritise features based on quantified demand Secure budget for DevRel, AI tooling, or marketing Validate pricing or packaging changes We translate population estimates and sentiment data into clear, actionable foresight, not charts.

Our work is: Global and independent Methodologically rigorous Focused on clean data Transparent in assumptions Clear about weighting and limitations. We are confident our insights can stand up to any CXO or Board scrutiny. Do you replace internal research or complement it? We complement it. Internal Analytics tells you what your users are doing.

For AI vendors, we support: Developer adoption tracking Productivity gains Tool benchmarking on awareness, engagement and more Enterprise buying criteria insights Security and compliance sentiment ROI perception We help you understand both AI tool builders demand and buying friction.
