Version V1

Transatlantic Trends: Immigration, 2009 examined attitudes and policy preferences related to immigration in Europe, Canada, and the United States. The survey concentrated on issues such as: general perceptions of immigration and immigrants, perceptions of legal and illegal immigrants, the impact of immigration on society, admittance of immigrants, immigration policies, immigration and integration, decision-making level, socio-political rights, welfare, government evaluation and number of immigrants, interaction with immigrants, and economic crisis. In addition, a list experiment was implemented in this survey. Several questions were also asked pertaining to voting and politics including vote intention, political party attachment, whether candidate parties' agendas on immigration will influence their vote, and left-right political self-placement. Demographic and other background information includes age, gender, ethnicity, citizenship, origin of birth (personal and parental), religious affiliation, age when stopped full-time education and stage at which full-time education was completed, occupation, type of locality, region of residence, and language of interview.
