GitHub added more than 36 million new developers in the past year, growing to over 180 million accounts, and now sees roughly one new developer join every second (GitHub Octoverse 2025). The independent research firm SlashData counts a narrower 47.2 million active software developers worldwide, of whom 36.5 million are professionals (SlashData, 2025). Meanwhile 84% of developers now use or plan to use AI tools, even though only 29% trust the output (Stack Overflow Developer Survey 2025), and the US median developer wage reached $133,080 (US BLS, 2024). This analysis consolidates data from Stack Overflow, GitHub Octoverse, JetBrains, SlashData, the US Bureau of Labor Statistics, and 3 other primary sources into one reference for the 2026 developer population.
TL;DR
- 47.2 million active software developers worldwide, including 36.5 million professionals, as of early 2025 (SlashData, 2025).
- 180 million-plus developer accounts on GitHub, up 36.2 million (+23%) in a single year (GitHub Octoverse 2025).
- The US had 28 million GitHub developers; India, at 21.9 million, is on track for one in three new developers by 2030 (GitHub Octoverse 2025).
- TypeScript became the most-used language on GitHub in August 2025, the biggest language shift in over a decade (GitHub Octoverse 2025).
- JavaScript remains the most commonly used language among survey respondents at 66%; Rust is the most admired at 72% (Stack Overflow Developer Survey 2025).
- 84% of developers use or plan to use AI tools, up from 76% in 2024, but only 29% trust AI accuracy, down from 40% (Stack Overflow Developer Survey 2025).
- 85% of developers regularly use AI tools; 20% save eight or more hours a week (JetBrains State of Developer Ecosystem 2025).
- US median developer wage was $133,080; the job market is projected to grow 15% from 2024 to 2034 (US BLS, 2024).
- The global software market was valued at $730.7 billion in 2024, forecast to reach $1,397.3 billion by 2030 (Grand View Research, 2025).
1. The Global Developer Population
Two credible sources put very different numbers on the same profession, and both are right. SlashData counts 47.2 million active software developers worldwide, while GitHub reports over 180 million accounts because it includes students, hobbyists, and casual coders alongside working professionals. The more telling signal is the slowdown: after a 21% spike in 2023-2024, SlashData’s population growth cooled to 10% over the last 12 months, and the amateur segment actually shrank by more than a million.
| Metric | Value | Source |
|---|---|---|
| Active software developers worldwide (early 2025) | 47.2 million | SlashData, 2025 |
| Professional developers | 36.5 million | SlashData, 2025 |
| Professional developer growth since Q1 2022 | +70% (from 21.8M) | SlashData, 2025 |
| Overall population growth, last 12 months | 10% (slowing) | SlashData, 2025 |
| Change in amateur developer segment, past year | -1 million+ | SlashData, 2025 |
| Total developer accounts on GitHub | 180 million+ | GitHub Octoverse 2025 |
| New GitHub developers in 2025 | 36.2 million (+23% YoY) | GitHub Octoverse 2025 |
| Rate of new GitHub developers | ~1 every second | GitHub Octoverse 2025 |
Divergence to note: SlashData measures active software developers via population sizing; GitHub counts registered accounts. Neither is wrong, but do not add them together.
2. Where in the World Developers Live
The center of gravity is shifting east. India added 5.2 million GitHub developers in 2025, about 14% of all new accounts, and overtook the United States as the largest contributor base to public and open-source projects. Western Europe and North America still hold the largest established communities at roughly 9.5 million each, but SlashData shows South Asia nearly doubling and Greater China nearly tripling since 2022.
| Metric | Value | Source |
|---|---|---|
| North America developers | ~9.5 million | SlashData, 2025 |
| Western Europe developers | ~9.5 million | SlashData, 2025 |
| South Asia developers (from 4M in 2022) | 7.5 million | SlashData, 2025 |
| Greater China developers (from 2.4M in 2022) | 5.8 million | SlashData, 2025 |
| US developers on GitHub | 28 million | GitHub Octoverse 2025 |
| India developers on GitHub | 21.9 million | GitHub Octoverse 2025 |
| Brazil developers on GitHub | 6.89 million | GitHub Octoverse 2025 |
| Indonesia developers on GitHub | 4.37 million | GitHub Octoverse 2025 |
Context: India is projected to account for one in every three new GitHub developers by 2030. The surge in contributions feeds directly into public code; see our open-source software statistics for the repository-level picture.
3. Programming Languages Developers Use
The rankings finally diverged in 2025, and the split is instructive. On GitHub, TypeScript overtook Python and JavaScript in August 2025 to become the most-used language by contributor count, the most significant shift in more than a decade. Yet among Stack Overflow’s survey respondents JavaScript still leads usage at 66%, while Rust holds its crown as the most admired language for a ninth straight year. Popularity, momentum, and admiration are three different measurements.
| Metric | Value | Source |
|---|---|---|
| JavaScript usage (survey respondents) | 66% | Stack Overflow 2025 |
| HTML/CSS usage | 61.9% | Stack Overflow 2025 |
| Python adoption jump, 2024 to 2025 | +7 points | Stack Overflow 2025 |
| Most-used language on GitHub (Aug 2025) | TypeScript, 2.636M contributors (+66.6%) | GitHub Octoverse 2025 |
| Python contributors on GitHub | ~2.6 million (+48.8% YoY) | GitHub Octoverse 2025 |
| Most admired language | Rust, 72% | Stack Overflow 2025 |
| Most desired language | Python, 39.3% | Stack Overflow 2025 |
| Top language developers want to learn next | Go, 11% | JetBrains 2025 |
Outliers: Docker usage jumped 17 points to 71% year over year, and PostgreSQL remained the most-wanted database at 47% for a third consecutive year (Stack Overflow Developer Survey 2025).
4. AI in the Developer Workflow
Adoption and trust are moving in opposite directions, which is the defining paradox of the 2026 developer. 84% of developers now use or plan to use AI tools, up from 76% in 2024, yet the share who trust AI accuracy fell to 29% from 40%. The friction is concrete: two-thirds are frustrated by answers that are almost right but not quite, and most have not adopted autonomous agents. For the AI tooling market itself, see our AI coding tools statistics; this section covers how the developer population uses and feels about it.
| Metric | Value | Source |
|---|---|---|
| Developers using or planning to use AI tools | 84% (from 76% in 2024) | Stack Overflow 2025 |
| Developers regularly using AI tools | 85% | JetBrains 2025 |
| Developers who trust AI accuracy | 29% (from 40% in 2024) | Stack Overflow 2025 |
| Actively distrust AI accuracy vs. trust it | 46% vs. 33% | Stack Overflow 2025 |
| Frustrated by “almost right, but not quite” AI answers | 66% | Stack Overflow 2025 |
| New GitHub developers using Copilot in first week | 80% | GitHub Octoverse 2025 |
| Developers saving 8+ hours a week with AI | 20% (~89% save 1+ hour) | JetBrains 2025 |
| Task speed increase using Copilot (controlled study) | 55% faster | GitHub/Accenture research |
Context: 52% of developers either avoid AI agents or stick to simpler tools, and 72% say they are not “vibe coding” (Stack Overflow 2025). Even so, 68% expect employers to require AI proficiency soon (JetBrains 2025).
5. Compensation and the Job Market
The profession still pays well and hires fast, but the numbers hide enormous geographic spread. The US median developer wage was $133,080 in 2024, and the Bureau of Labor Statistics projects 15% job growth through 2034, five times the all-occupation average. Yet the same role that pays a $200,000 median for US engineering managers pays $52,308 in India, a reminder that a single global salary figure means little.
| Metric | Value | Source |
|---|---|---|
| US software developers, QA analysts and testers employed (2024) | 1.7 million | US BLS, 2024 |
| US median annual wage (May 2024) | $133,080 | US BLS, 2024 |
| US top 10% wage | more than $211,450 | US BLS, 2024 |
| US bottom 10% wage | less than $79,850 | US BLS, 2024 |
| Projected US job growth, 2024 to 2034 | 15% (vs. 3% average) | US BLS, 2024 |
| Projected annual job openings | 129,200 | US BLS, 2024 |
| Highest-paid role median (senior executive) | $139,218 | Stack Overflow 2025 |
| Engineering manager median, US vs. India | $200,000 vs. $52,308 | Stack Overflow 2025 |
Context: engineering manager medians landed at $136,141 in the UK and $118,335 in Germany, between the US and India extremes (Stack Overflow Developer Survey 2025).
6. Who Developers Are: Demographics, Education, and Work Setting
The workforce is young, credentialed, and largely remote. A third of developers are aged 25 to 34, and one in four has five years or fewer of professional experience, describing a field still absorbing a large early-career cohort. Formal computer-science education is not the norm: while 68% hold a bachelor’s or master’s degree of some kind, just under half learned to code formally in school, per Stack Overflow.
| Metric | Value | Source |
|---|---|---|
| Developers aged 25 to 34 | 33.6% | Stack Overflow 2025 |
| Developers with 1 to 5 years of professional experience | 24.8% | Stack Overflow 2025 |
| Bachelor’s degree holders | 42.1% | Stack Overflow 2025 |
| Full-stack developers | 27% | Stack Overflow 2025 |
| Working fully remote | 32.4% | Stack Overflow 2025 |
| Junior developers who find the job market challenging | 61% | JetBrains 2025 |
| Senior developers who find the job market challenging | 54% | JetBrains 2025 |
| Developers who code for fun outside work | 52% | JetBrains 2025 |
Context: 26.2% of developers hold a master’s degree and 69.8% are employed full-time, with independent contractors and freelancers making up another 13.9% (Stack Overflow 2025). For the broader shift toward distributed teams, see our remote work statistics, and for the contract side, note the overlap with games work in our game development statistics.
