GitHub Developer Index: reachability and availability by city
Aggregated statistics on 85,938 active GitHub developers in the United States, France and the United Kingdom, broken down by metropolitan area, technology and engineering role.
Each row reports how many developers the group contains, what share publish an email address on their GitHub profile, and what share have flagged themselves as available for hire.
Last updated: 2026-10-02. Refreshed monthly.

A developer is counted once per group, never once per technology. Rows are a cube: the country total, each city, each technology, each role, and the city-by-technology crossings.

Method, and what this does not measure
Figures come from public GitHub profiles and repositories, enriched and deduplicated. Locations are free text on GitHub, so they are normalised to a metropolitan area before counting, and suburbs fold into their hub.
Three limits worth stating.
This measures the developers we have indexed, not every developer in a city: a place with fewer rows may simply be less covered.
"Open to work" is GitHub's own self-declared flag, which people set and then forget. Read it as a floor, not a census.
Groups smaller than 50 developers are excluded entirely. Below that, a percentage is rounding noise rather than a measurement.
Privacy
This dataset contains no individual records: no usernames, no email addresses, no profile URLs. Only counts and percentages over groups of at least 50 people.
