The global developer population reached 47.2 million in early 2025, but growth has decelerated sharply to just 10% in the last 12 months—down from 21% the previous year. SlashData’s latest Global Developer Population Trends report warns this may mark the beginning of a plateau phase, with the population potentially stopping growth entirely within 1-2 years. Beneath this overall slowdown lies a stark divergence: professional developers surged 70% from 2022 to 2025 (21.8M to 36.5M), while amateur developers declined by over 1 million in just the last year.
Professional Developer Boom, Amateur Developer Bust
From early 2022 to early 2025, professional developers grew 70% (21.8M to 36.5M). Meanwhile, amateur developers—hobbyists, bootcamp students, and part-time learners—barely grew and actually declined by over 1 million in the last year. Professionals now represent 77% of all developers, up from roughly 70% three years ago. The developer population isn’t just slowing—it’s bifurcating.
The demographic shift is equally stark. Developers aged 18-24 dropped from 33% in early 2022 to 23% in early 2025—a 10-point decline. Those aged 35-44 rose from 22% to 26% during the same period. Fewer young people are entering the field, and those who do face brutal job market realities. The traditional path “learn to code → junior job → senior job” is breaking down.
Companies are keeping experienced developers while cutting entry-level roles, creating a talent pipeline crisis. No juniors today means no seniors in five years. SlashData’s research team notes that if the slowdown continues at the same rate, the population may reach a point where it’s no longer growing within one to two years.

Job Market Contraction: 49% Fewer Postings
Software engineering job postings have dropped 49% from their peak. Entry-level hiring is down 25% year-over-year. Tech layoffs totaled 347,600 workers over 2023-2024 (263K + 84.6K), flooding the market with experienced developers competing for the same shrinking pool of jobs. Entry-level unemployment for computer engineering and CS grads sits at 7.5% and 6.1% respectively—well above the national average.
Indeed’s Hiring Lab data shows software job postings at 65% of February 2020 levels. Medium analysis documented 200+ job applications with zero offers as a common junior developer experience. One senior developer can now do the work of a three-person team with AI assistance, reducing team size requirements across the industry.
The “developer shortage” narrative is dead for entry-level positions. Bootcamp grads and career switchers face fierce competition from 300K+ laid-off experienced engineers. The market has shifted from employer desperation to candidate oversupply. Anyone entering the field now should expect 6-12+ months to land a first job, if at all.
AI’s Dual Impact: Tool for Seniors, Threat to Juniors
Seventy-five percent of engineers now use AI coding assistants like GitHub Copilot, enabling 30% productivity gains and smaller team sizes. However, this same AI adoption is eliminating entry-level positions. The tasks junior developers used to do—debugging, boilerplate code, test writing—are now handled by AI tools. Thirty-seven percent of employers say they’d rather “hire” AI than a recent graduate.
Salesforce reported 30% productivity increases while maintaining flat headcounts. Stack Overflow’s analysis shows entry-level tech hiring dropped 25% year-over-year as companies realize one senior engineer with AI can replace what used to require multiple juniors. A Stanford Digital Economy Study found employment for software developers aged 22-25 declined nearly 20% from its late 2022 peak.
AI isn’t replacing senior developers wholesale, but it is reshaping the profession. The entry-level “apprenticeship” path is being eliminated. Companies cutting juniors today are creating tomorrow’s senior talent shortage. The vicious cycle: fewer juniors means no training ground, which means a senior talent shortage in 3-5 years.
Bootcamp Industry Collapse and Salary Bifurcation
The coding bootcamp industry experienced mass closures in 2024. 2U shuttered its university-partnered programs. Epicodus closed due to insufficient enrollment. Momentum Learning, App Academy, Turing, Tech Elevator, Hack Reactor, Kenzie Academy, and Codeup all shut down or drastically scaled back. The amateur developer market—bootcamps’ primary customer base—is shrinking, not growing.
BestColleges reports that public enthusiasm for coding bootcamps has cooled significantly as AI automates routine coding tasks and entry-level jobs disappear. The Bureau of Labor Statistics projects an 11% decline in computer programming jobs between 2022 and 2032, contradicting the “coding shortage” narrative bootcamps marketed. With software job postings down 30% from pre-pandemic levels, the $15K-20K bootcamp investment shows dubious ROI.
Compensation trends mirror the market bifurcation. Entry and mid-level developers saw modest 1-2% salary growth (2024-2025), while senior engineers gained 4%, staff engineers 7%, and engineering managers 10%. AI engineering roles command a 12% premium over general software engineering positions. The median developer salary sits at $121K-128K, but entry-level often earns $60-80K with huge geographic variance.
The market is rewarding experience and specialization—especially AI expertise—while devaluing entry-level skills that AI tools can replicate. Companies won’t pay for juniors but desperately need experienced developers, yet they’re eliminating the junior roles that create future seniors. The “learn to code for $100K+ salary” promise is outdated for 2025.
What This Means Going Forward
The developer population is approaching 50-52 million by 2027 if current deceleration trends continue. Market saturation in developed countries, AI-driven productivity gains reducing team size requirements, and a brutal entry-level job market all point toward a new equilibrium. The tech industry is maturing past its exponential growth phase.
However, this doesn’t necessarily signal decline. The shift from amateur to professional suggests the field is maturing rather than contracting. Professional developers continue growing, aging into senior roles, and commanding strong compensation. The challenge is the talent pipeline: eliminating entry-level positions today creates a senior shortage tomorrow.
Geographic trends also matter. The US and European markets are saturated with minimal growth, while China and India experience 40%+ growth rates. Evans Data Corporation projects India will overtake the US in developer population within the next 1-2 years. Remote work enables access to these growing talent pools, but language, time zones, and local market dynamics complicate direct hiring.
Key Takeaways
- Developer population growth has decelerated to 10% (from 21% peak), with SlashData warning of a plateau within 1-2 years as the market matures
- Professional developers surged 70% (2022-2025) while amateur developers declined by 1M+, signaling a shift from growth phase to market maturity
- Job market contraction is severe for entry-level (49% fewer postings, 25% less hiring, 347K layoffs) but strong for senior roles (+4-10% compensation growth)
- AI tools create a productivity paradox: 30% gains for seniors enable smaller teams, but eliminate junior tasks and entry-level positions
- Companies cutting junior roles today face a senior talent shortage in 3-5 years—the talent pipeline crisis is self-inflicted
- Bootcamp industry collapse (mass closures in 2024) reflects amateur market contraction and uncertain ROI in AI-augmented development environment
- Geographic shift underway: US/EU markets saturated while China/India grow 40%+, with India projected to become largest developer market by 2026-2027
