Abstract

In 2018, representatives from all the Swedish parliamentary parties (plus the Feminist Initiative) agreed to participate in and conduct an online survey among their party members. The questions are similar to those asked in the Swedish party membership survey in 2015. The survey was administered by the Laboratory of Opinion Research (LORE) at the University of Gothenburg. At the end of the field period at the beginning of May 2019, a total of 20,605 party members had responded. The response rate varies between 9.4 percent (Feminist Initiative) and 29.9 percent (Christian Democrats). In spring 2022, the data file for SPMS 2019 was reworked to enable better possibilities of sharing data upon request. This entailed the recoding of two variables (year of birth and year of entry into the party), as well as the removal of all variables and response alternatives with free text fields and postcodes. Below is a list of recoded or deleted variables. Further information can be found in the enclosed code books. The complete dataset is available with restricted access. Recoded variables: yearmember; yearofbirth Removed variables: Q32_2_text; Q33_2_text; Q112; Q110_6_text; postcode_clean Added variables: county, uncertain_county The data is available as a STATA dataset (.dta) as well as coded comma-separated values (.csv).

Sampling procedure

In January 2019, the party secretaries received a link to the survey that was party-specific, but not person-specific. The parties sent out the link to the survey to all party members whose e-mail address they had access to via their own newsletters or e-mail lists. Only the Social Democrats chose to send the survey to a representative sample of the party's members (n = 6500). The Sweden Democrats could not find a way to send the survey to their members before all surveys were closed and are thus not included in the final product. The gross sample size is 117,381 party members (L = 15,636; Mp = 10,719; S = 6,500; V =23,260; KD = 13,000; M =25,200; Fi = 6,000; C = 17,066)
