CERD/C/DZA/CO/15-19 8. It welcomes the amendments made to the Nationality Code in February 2006 allowing for children born abroad of an Algerian mother and a foreign father to acquire Algerian nationality. 9. The Committee notes with interest that, during the period under review, the State party ratified several international instruments, including: (a) The International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families, in 2005; (b) The Convention on the Rights of Persons with Disabilities, in 2009; (c) The Optional Protocol to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography, in 2006; (d) The Optional Protocol to the Convention on the Rights of the Child on the involvement of children in armed conflict, in 2009; (e) The United Nations Convention against Transnational Organized Crime, in 2002; and its protocols to prevent, suppress and punish trafficking in persons, especially women and children, and against the smuggling of migrants by land, sea and air, in 2004. C. Concerns and recommendations Relevant data 10. While noting the State party’s position that it does not collect population data disaggregated by ethnic origin, the Committee notes the absence from the report of statistical data on the composition of the population. It also notes the lack of relevant socioeconomic indicators on the enjoyment of the rights guaranteed under the Convention by members of various groups, in particular the Amazigh and non-citizens, as such data are necessary to determine the progress made and difficulties encountered in implementing the provisions of the Convention (arts. 1 and 5). In the light of its general recommendation No. 8 (1990), concerning the interpretation and application of article 1, paragraphs 1 and 4, of the Convention and paragraphs 10 to 12 of its revised guidelines for the preparation of periodic reports (CERD/C/2007/1), the Committee recalls the usefulness of disaggregated data on the ethnic composition of the population. Relevant information on the socioeconomic and cultural situation and living conditions of different groups within the population can be used by the State party as a valuable tool for taking the necessary measures to ensure the enjoyment by all of the rights enshrined in the Convention and to prevent discrimination based on ethnic origin and nationality. Definition of racial discrimination 11. The Committee regrets that the State party has not yet adopted a definition of racial discrimination in line with article 1 of the Convention (art. 1). Recalling its general recommendation No. 14 (1993), concerning article 1, the Committee recommends that the State party incorporate into its domestic legislation a definition of racial discrimination that is consistent with article 1 of the Convention and that applies to all areas of public and private life. 2 GE.13-42646
