About this table

Description	Paired conjoint: 2,211 German adults (TGM panel, December 2024) made 7 choices between refugee-policy packages varying admission policy (third-country transfer and resettlement), refugee selection criteria, partner-country conditions and welfare access, and rated each package 1-7; respondents had first been assigned one of three framing primes.
