However, OA publishing still has a global imbalance.

Additional metrics were obtained from each journal website.

The leading contributors were India (23.96%), the USA (14.98%) and China (6.54%). Low-income countries accounted for 0.37% of total publications, followed by upper-middle-income (17.97%), lower-middle-income (29.07%), and high-income (52.54%) countries. The geographical distribution of publication volume was as follows: Southeast Asia (25.38%), Europe (23.18%), Western Pacific (18.92%), Americas (23.91%), Eastern Mediterranean (8.03%) and Africa (0.59%). Nineteen journals required a mean article processing charge (APC) of US $2,164.89, accounting for 51.89% of the total publications. India ranked first in non-APC journals, while the USA led in APC journals<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>.
