For modern day cupids data replaces dating
Response to the main survey in 2009 from subjects, all of whom were already in the Knowledge Networks panel, was 71%. Note for SPSS and SAS users: we have replaced the portable versions of the SPSS and SAS files with the and .sas7bdat versions, respectively, to accommodate the long variable names in the dataset.If we include the the prior initial Random Digit Dialing phone contact and agreement to join the Knowledge Networks panel (participation rate 32.6%), and the respondents’ completion of the initial demographic survey (56.8% completion), the composite overall response rate is a much lower .326*.568*.71= 13%. The Stanford research team does all their work in STATA, so if you find discrepancies between the SAS or SPSS versions of the dataset and the documentation, please let us know.

Respondents who had no spouse or main romantic partner were dropped from the Main Survey.
Unpartnered respondents remain in the dataset, and demographic background variables are available for them. Wave 6 was Internet only, so people who had left the Gf K Knowledge Panel were not contacted.
Panelists are recruited via random digit dial phone survey.
Survey questions were mostly answered online; some follow-up surveys were conducted by phone.
