I've read about how the Belgians issued ID cards to the inhabitants of their colony Ruanda-Urundi (later independent under the names of Rwanda and Burundi):
Indeed, the Belgian colonists classified a person as Tutsi if they had a long nose (or ten cows). (Caselli/Coleman: On the theory of ethnic conflict, 2012, page 28)
However, I was not able to find any information on whether these were applied to men and women alike or whether different means of distinction were used for women.
Were phenotypical features and wealth also distinctive for women, or were women categorized along other means, e.g. their husband's / father's categorization?
