Examination of the familial correlations (Table S11) provides evidence that heritability estimated with family-based samples may be inflated if, unlike the analysis we performed with ASSOC, the sibling and marital correlations are ignored.
If assortment results from marital interaction, the spouse correlation increases as a function of duration of marriage and in general the correlation between parents of twins will be higher than between twins and their spouses [24].
For example, Beijbom ( 1971) finds a positive and statistically significant effect of marriage on Swedish immigrants' propensity to obtain citizenship in the USA, while Guest ( 1980) does not find any discernable correlation between marital status and naturalisation.

Correlations between marital status and emotional support was moderate in strength (r = 0.29, p < 0.001), while correlation between marital status and social participation (r = 0.04, p < 0.001), and marital status and social ties were weak in strength (r = 0.05, p < 0.001).
Our study has not confirmed these findings, since no correlations between marital status and QoL domains was found in any of groups (data not showed).
Keynesians can explain different labor-market experiences by demographic groups to the degree that groups differ in their propensities to work in declining industries, except in this case marital status has very little correlation with industry of employment.
