43 at-risk-of-poverty rate before and after social transfers (Eurostat), is used as a comparative value to assess national situations. 169. The Committee considers that it follows from its conclusion in respect of Article 31 that the policy in respect of housing for the poorest is insufficient. Therefore, it finds a lack of a co-ordinated approach to promote the effective access of persons who live or risk living in a situation of extreme poverty to housing. 170. The committee therefore holds that the situation amounts to a violation of Article 30. SIXTH PART : ON THE ALLEGED VIOLATION OF ARTICLE 30 OF THE REVISED CHARTER, TAKEN IN CONJUNCTION WITH ARTICLE E OF THE REVISED CHARTER A. Arguments of the parties a) ATD Fourth World 171. ATD Fourth World alleges that families living in poverty are discriminated against in respect of effective access to their rights. In particular, it points out that the people concerned do not have a national identity card: they are refused such a card on the grounds that they have no address. Yet the families concerned receive mail, electricity bills and tax demands. This practice is discriminatory and is clear evidence of a refusal to treat these families as citizens of the municipality. It makes it even more difficult for them to obtain access to other social rights, which require possession of an identity card. b) The Government 172. The Government contends that families living in poverty are not victims of discrimination on the part of public services. 173. National identity cards are issued to travellers in the normal way, in accordance with the regulations, whether they have settled or not. Eight of the persons concerned do hold national identity cards, six of these issued by the Argenteuil sub-prefecture. B. Assessment of the Committee 174. The Committee considers in the light of the arguments presented in §§ 169-170, that the situation amounts also to a violation of Article 30 of the Revised Charter taken in conjunction with Article E.
