There is a small number of studies that distinguish spouse from other relationships. See Figure S5 of this paper. I don’t think there’s enough data to draw a strong empirical conclusion. Most of our data for estimating SAR is from China/Korea/Taiwan and I’d guess these are mostly nuclear families or extended family (not many group house / flatmates).
