Some countries also report more specific objectives for some parts of the housing sector. Objectives for the social rental sector, for example, include reducing its construction and running costs (Denmark); improving its regulation (the Czech Republic); or enabling a more diverse range of providers (New Zealand). The phenomenon is significant in other OECD and key partner countries as well: around 30% of the urban population lives in slums in in India and Brazil, 23% in Indonesia and South Africa and 19% in Mexico (see UN Millennium Development Goals Database, 2014). Due to rapid urbanization in developing countries, the number of slum dwellers is projected to grow in the coming years (UN-Habitat, 2014) and eradication of urban slums by 2020 has been included by the United Nations among the targets of the UN Millennium Development Goals (Target 11 of Goal 7).
