Families stand as the primary social units; households are recurrent locations for social interactions. No matter that there are other partners in conversation – parents, children, friends, neighbors, workmates, and acquaintances – people talk to their spouses and domestic partners. In all these intimate social units, not only words but groans, smiles, frozen silences, grimaces, laughter, and shouts convey preferences. No matter the level of interest of politics in the household, the greater the number of thoughts exchanged, the more they discuss politics (Walsh 2004).

Families are the primary locus of political discussions; here, national politics enters the personal space of each citizen (Glaser 1959–60; Hays and Bean 1992; March 1953–4; Stoker and Jennings 1995; Verba, Schlozman, and Burns 2005; and Zuckerman and Kotler-Berkowitz1998). Absent information on these issues in GSOEP or BHPS, we bring illustrative evidence from other sources. For example, in 1987, more than 0.75 of Britons report that the person with whom they most frequently discuss politics is a family member who lives in their household; 0.66 single out their spouse or live-in partner as that person; 0.30 talk politics with no one but family members, and less than 0.05 do not include a family member among the two persons with whom they most frequently discuss politics (Zuckerman, Kotler-Berkowitz, and Swaine 1998).
