Stack Overflow Developer Survey, 2025
The methodology reports 49,009 included responses from 177 countries, fielded May 29 to June 23, 2025.
When this is useful
You want to form hypotheses about developer interests and then check them with your intended users
What is measured
Developer survey responses; each question can have a different response denominator
Use each question's eligible unique responses; multiple-select percentages are not necessarily shares of all developers
Cohort and collection window
Respondents recruited primarily through Stack Overflow-owned channels with eligibility and consent screening
May 29–June 23, 2025
A fair comparison
Write your own metric definition and cohort beside the report's definition. If they differ, use the report to frame a question rather than assigning your company a percentile or target.
Put it to work
- Match the metric, period and eligible population.
- Read the original method and subgroup notes; record exclusions and unknowns.
- Compare with your own cohort and choose an investigation rather than importing a universal target.
Limits and tradeoffs
Voluntary, channel-recruited responses are not a representative census. This methodology profile does not claim a verified technology-adoption percentage from every results chart.
