About this table

Description	Ethiopian university students (n = 1,008 with a usable task; endline and expansion samples pooled) each chose between two hypothetical federal arrangements in up to 2 pairs, varying who hires civil servants, police structure, who decides language/history policy, and how state borders are drawn. Outcome: forced choice.
