ANNEX I. >> M  etadata sheets on selected indicators The European Federation of National Organisations working with the Homeless (FEANTSA) developed a typology of homelessness and housing exclusion called ETHOS. Its definition covers four categories: rooflessness; houselessness; insecure housing; and inadequate housing. Thus, people living in insecure accommodation (e.g., temporarily with family/friends, illegal occupation of land, no legal (sub)tenancy), or under threat of eviction and violence, in temporary/ non-conventional structures in unfit housing or in extreme overcrowding are also included in the definition. (See www.feantsa.org/code/en/pg.asp?Page=484, accessed 2 July 2012). Eurostat also proposed a working definition of housing deprivation (including homelessness) comprising primary and secondary homelessness. Secondary homelessness includes persons living in non-temporary arrangements of shelter provided by a public body or NGO, without a tenancy agreement for lack of a home of their own (e.g., dormitory, room or studio in a communal facility, hotel or guest house, accommodation temporarily provided by friends or relatives). (See http://epp.eurostat.ec.europa.eu/cache/ITY_OFFPUB/KS-CC-04-008/EN/KSCC-04-008-EN.PDF, accessed 2 July 2012). Examples of provisions relevant to the right to adequate housing: Universal Declaration of Human Rights, art. 25; International Covenant on Economic, Social and Cultural Rights, art. 11 (1); International Convention on the Elimination of All Forms of Racial Discrimination, art. 5 (e) (iii); Convention on the Elimination of All Forms of Discrimination against Women, art. 14 (2) (h); Convention on the Rights of the Child, art. 27 (3); International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families, art. 43 (1); and Convention on the Rights of Persons with Disabilities, art. 28 (1) and (2) (d). 166 Human Rights Indicators
