Moreover, new legislation allows usage of minority languages in federal radio and TV broadcasting. In 2007, there were 6,260 schools which provided teaching in 38 minority languages. Over 75 minority languages were taught as a discipline in 10,404 schools. Ministers of the Council of Europe have noted efforts to improve the supply of minority language textbooks and teachers, as well as greater availability of minority language teaching. However, as Ministers have noted, there remain shortcomings in the access to education of persons belonging to certain minorities. There are more than 2,000 national minorities' public associations and 560 national cultural autonomies, however the Committee of Ministers has noted that, in many regions, the amount of state support for the preservation and development of minority cultures is still inadequate. Alvaro Gil-Robles noted in 2004 that there is a significant difference between "eponymous" ethnic groups and nationalities without their own national territory, as resources of the latter are relatively limited. Russia is also home to a particular category of minority peoples, i.e. small indigenous peoples of the North and Far East, who maintain very traditional lifestyles, often in a hazardous climatic environment, while adapting to the modern world. After the fall of the Soviet Union, the Russian Federation passed legislation to protect the rights of small northern indigenous peoples. Gil-Robles has noted agreements between indigenous representatives and oil companies, which are to compensate for potential damage to people's habitats due to oil exploration. As the Committee of Ministers of Council of Europe noted in 2007, despite some initiatives for development, the social and economic situation of numerically small indigenous peoples was affected by recent legislative amendments at the federal level, removing some positive measures as regards their access to land and other natural resources. Alvaro Gil-Robles noted in 2004 that, like many European countries, the Russian Federation is also host to many foreigners who, when concentrated in a particular area, make up so-called new minorities, who experience troubles e.g. with medical treatment due to the absence of registration. Those who are registered encounter other integration problems because of language barriers. The Committee of Ministers noted in 2007 that, despite efforts to improve access to residency registration and citizenship for national minorities, those measures still have not regularised the situation of all concerned. In October 2002 the Russian Federation has introduced new legislation on legal rights of foreigners, designed to control immigration and clarify foreigners' rights. Despite this legal achievement, as of 2004, numerous foreign communities in Russia faced difficulties in practice (according to Álvaro Gil-Robles).
