Replication Data for: \"Is climate change a valid reason for migration? Evidence from a conjoint experiment\"

Significant changes in climate that impact livelihoods, physical health, and human security raise the question: Is climate change perceived as a valid criterion for long-term immigration, and if so, by whom and under what circumstances? To address these questions, we conducted a well-powered conjoint experiment with a quota-representative sample of Dutch respondents. Consistent with recent literature, our findings reveal that, in terms of public favorability, climate migrants are perceived more favorably than economic migrants but less favorably than asylum seekers fleeing persecution. Moreover, our results challenge the expectation that political ideology and cli-mate attitudes moderate the favorability toward climate migrants.对民众生计、身体健康与人类安全造成显著影响的气候变化，引发了一项核心研究议题：气候变化是否可被视作长期移民的合法依据？若可，那么哪些群体、在何种情境下会将其视为此类依据？为解答上述问题，本研究针对荷兰配额代表性样本群体开展了一项效力充足的联合实验（conjoint experiment）。与近期相关学术文献的结论一致，本研究结果显示：从公众支持度维度来看，气候移民（climate migrants）相较于经济移民更受公众青睐，但相较于因迫害而逃亡的寻求庇护者（asylum seekers），则认可度更低。此外，本研究结果对“政治意识形态与气候态度会调节公众对气候移民的支持度”这一主流预期提出了挑战。
