Which ethnic group makes up about half of Eritrea’s population?

The ethnic group that makes up approximately half of Eritrea’s population is the Tigray people.12

In Eritrea, this group is sometimes referred to as Tigrinya, though linguists note that the suffix -nya is an Amharic term meaning "language of," and nomenclature for the group remains fluid due to contemporary political sensitivities. The Tigray are a sedentary agricultural people who primarily inhabit the Eritrean highlands and are also found in the adjacent Tigray region of Ethiopia.12
