Fascinating data!
Talking with newcomers from Eritrea, it sounds like the number of years there would be significantly longer. Maybe it depends on the province?
WOW. I googled conscription in Eritrea, and several sources quantified is as “indefinite.” WHAT.
According to Amnesty international, “A large proportion of the adult population of Eritrea is currently engaged in national service, which is mandatory for men and women between the ages of 18 and 50. While the service period is supposed to be 18 months, this is frequently extended indefinitely. All schoolchildren are required to complete their final year of schooling at Sawa military camp, which results in children being conscripted into military service. ”

Devastating!! And it’s fascinating that Eritrea was selected as one of the sample countries, given that there are many more countries that were not included in the data visualization that have compulsory military service. I’m going to update the page with this information. Thank you to you and your students!
