2015). The brand new GGS belongs to the Generations and you will Gender Program and you will, since 2015, it’s got accumulated group and you will socioeconomic details about the new population within the nineteen European countries (Vikat et al. 2007; Thomson mais aussi al. 2015). For the Sweden, the latest GGS is a telephone-depending survey which have a goal people out of 18,one hundred thousand some one old 18–79 ages. As a whole, 9688 responded to the survey (reaction speed 53.8%).

To study parents’ thinking with the tastes towards sex of kids i use the 2012 Swedish Generations and Gender Questionnaire (GGS) (Thomson et al

Specifically, our research inhabitants contains one to- and two-guy moms and dads have been from inside the childbearing age at the time of the newest interviews.

This pursue this is employed by new GGS questionnaire, since most concerns into virility tastes was in fact simply expected to this subpopulation. All in all, 497 that-guy and 922 a few-child mothers advertised whether or not they really wants to have another son. Footnote 1 Individuals who advertised a wish for another man was basically and asked their taste toward intercourse of that guy. In addition to “boy” and you may “lady,” there clearly was the possibility “it doesn’t matter.” We also use research on the follow-up questionnaire to look towards parents’ perceptions about precisely how an extra child you are going to apply to its stays in the long run and you will whether they noticed stress from friends for other guy. Following the exact same concept of childbearing decades, all in all, 512 two-child parents taken care of immediately new realize-up survey.

All rates according to the GGS analysis made use of take to loads. Rely on times getting proportions have been calculated having fun with a great logit change, which suppresses overshoot in the example of low otherwise most large proportions-we.e., this new limitations regarding estimated times you should never reach less than no otherwise over 100% (Brownish mais aussi al. 2001).
