Studies of public opinion on immigration have focused on the responses to survey questions about whether the individual would prefer more or less immigration (preference) but not on his or her assessment of its importance as a policy issue (salience). Analysis of data from the European Social Survey and Eurobarometer indicates that preference and salience are associated with different individual-level characteristics. At the national level they move differently over time and in response to different macro-level variables. Both dimensions of opinion must be taken into account as influences on the formation of immigration policy.

欧洲移民民意：偏好和显着性

关于移民的公众舆论研究集中于对个人是否愿意或多或少地偏爱（偏好）的调查问题的回答，而不是针对其作为政策问题的重要性（显着性）的评估。对来自欧洲社会调查和欧洲晴雨表的数据的分析表明，偏好和显着性与不同的个人水平特征相关。在国家一级，随着时间的推移，它们针对不同的宏观水平变量而采取不同的行动。必须考虑两个方面的意见，因为这会对移民政策的形成产生影响。
