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).
