+*** Idea
+    Archived commit metadata contains public information that can be mined to
+    study long-term trends of diversity, equity, and inclusion (DEI) traits of
+    the global population of public code contributors.
+
+*** Key findings on the gender gap
+    - Male authors contributed 92% of public code commits up to 2019.
+    - The ratio of female authors (and their contributions) has grown stably
+      for 15 years reaching for the first time 10% of yearly contributions
+      in 2019.
+    - The COVID-19 pandemic has reversed the trend.
+
+** Diversity, equity, and inclusion (cont.)
+
+*** Key findings on the geographic gap
+    - The early decades of public code were dominated by contributions from
+      North America, followed by a period of alternating dominance between
+      North America and Europe.
+    - Since then geographic diversity has increased constantly, with raising
+      importance of contributions from Central and South America.
+    - The trend of increased female contributions is almost worlwide, with the
+      notable exception of specific regions of Asia were it is either slower or
+      flat.
