| # GitHub Developer Index: reachability and availability by city |
|
|
| Aggregated statistics on **82,493 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: **2026-09-23**. Refreshed monthly. |
|
|
| ## Files |
|
|
| | File | Scope | |
| |---|---| |
| | `starhunt-developers.csv` | All three markets | |
| | `starhunt-developers-us.csv` | United States | |
| | `starhunt-developers-fr.csv` | France | |
| | `starhunt-developers-uk.csv` | United Kingdom | |
|
|
| ## Columns |
|
|
| | Column | Meaning | |
| |---|---| |
| | `country` | United States, France or United Kingdom | |
| | `metro` | Metropolitan area, or `*` for the whole country | |
| | `technology` | Technology, or `*` for all | |
| | `role` | Engineering role, or `*` for all | |
| | `developers` | Number of developers in the group | |
| | `public_email_pct` | Share with a public email address on their profile | |
| | `open_to_work_pct` | Share whose profile is flagged as available for hire | |
|
|
| 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. |
