What is it about?
Where do political parties stand on immigration? This article examines different methods to place parties on immigration in retrospective. It draws on different methods to extract positions from party manifestos and compares them to expert surveys. I manually coded party manifestos with a conventional codebook, and using a check‐list, but also used automatic coding (Wordscores) and a dictionary of keywords. Moreover, I used a media analysis to examine claims by political parties, and a retrospective assessment of how party positions developed. The data are on Switzerland 1991 to 2011. There are high correlations between many methods, but the different methods tend not to agree on the exact positions.
Why is it important?
Immigration developed into a major political cleavage, and it is important to know where parties stand. There are different methods, and we need to know which ones provide valid estimations.
