What the 2020 Stack Overflow Survey Reveals About Developer Salaries, Tools, and Demographics

Stack Overflow conducted its 2020 developer survey with almost 65,000 respondents, providing a comprehensive view of how developers learn, the tools they use, and what they value.

Key Results

Developers using Perl, Scala, and Go earn the highest average salaries (around $75,000), with Scala leading in the United States.

Site Reliability Engineers and DevOps specialists are the highest‑paid roles; 80% consider DevOps very important, and 44% have at least one dedicated DevOps team member.

When faced with coding problems, 90% of respondents turn to Stack Overflow.

More than 75% of developers work occasional overtime (1‑2 days per quarter), while 25% work overtime weekly.

55.2% identify as backend developers and 54.9% as full‑stack developers; the most common self‑identified combination is backend, frontend, and full‑stack.

78% of developers treat programming as a hobby.

Technical leads and engineering managers have the most professional coding experience (up to 16.5 years at VP level). Among individual contributors, system administrators, DBAs, and desktop/embedded developers are the most experienced, whereas web developers, researchers, and data scientists tend to have less experience.

Over 54% wrote their first line of code before age 16; only 13% started in their 20s. Developers from Brazil and India start later (average age 15) compared to those from Poland and Germany.

Approximately 75% of respondents have at least a bachelor’s degree or higher.

Python fell from second to third place in the most‑loved programming languages, overtaken by TypeScript.

ASP.NET surpassed React.js as the most‑loved web framework, with Gatsby rising to fifth.

Redis remains the most popular database, followed by PostgreSQL and Elasticsearch; IBM DB2 is viewed as the most intimidating, while MongoDB is the most desired to learn.

Linux is the dominant platform, with Docker and Kubernetes ranking second and third.

82% use GitHub for collaboration, and over half use Slack.

Technology clusters form ecosystems: web technologies connect via SQL to Microsoft stacks, while operational tools link Linux to the Python ecosystem.

These findings illustrate global developer demographics, compensation, tool preferences, and emerging trends, offering a reference point for professionals planning their career development and for organizations shaping their technical strategies.
