Olivia D’Aoust recently alerted me to the useful site JuriGlobe, which discusses legal regimes the world over, and also passed along a map she’d made based on their data. (Potential employers, she’s on the job market with a fascinating paper on electoral violence in Burundi – go hire her!)
What really strikes me here is how much variance there is in the recognition of customary law. Why does Togo use it when neighboring Benin doesn’t? Or Mozambique but not Angola? There’s no clear correlation with colonial heritage or the use of common vs. civil law otherwise.
