In this article, we study variations in co-residence with kin in the Netherlands in the late nineteenth and early twentieth centuries. We use the reconstructed life courses of 17,527 individuals derived from the Historical Sample of the Netherlands (HSN) database. The life-course approach allows us to look at co-residence from the perspectives of both the receiving households and the co-resident kin. What made households take in relatives and do we find a preference for one type of relative over another? What was the background of people who decided to co-reside in another household? How important were family-related altruistic motives compared with economic ones? The outcomes suggest the predominance of altruistic motives for co-residence, apart from persistent inheritance customs in the eastern part of the country. Copyright
