How much research Ghanaian institutions published each year from 1853 to 2027, and how much of it is open access. A handful of works carry a publication year that cannot be right — a stray nineteenth-century date, or one in the future — and they are left as the source has them rather than quietly removed. Sourced from OpenAlex, CC0. 144 records.
This dataset includes projected figures up to 2027, beyond today.
Every column this dataset returns, with its type. This is the shape of the API response.
| Field | Type |
|---|---|
| year | INTEGER NOT NULL |
| works | BIGINT |
| open_access_works | BIGINT |
| open_access_share | DECIMAL(10,4) |
