Multi-person households
There were five regions in the EU where the share of multiperson households (composed of unrelated individuals) was in double-digits; all of these were in urban areas of the United Kingdom, namely: Inner London - East; Inner London - West; Outer London - West and North West; Nottingham; and Brighton and Hove. Among the 30 regions in the EU with the highest share of multiperson households composed of unrelated individuals, some 27 were regions in the United Kingdom, the three exceptions being Hlavní Mesto Praha (8.4 %), Byen København (7.7 %) and Heidelberg, Stadtkreis (also 7.7 %).
