In 2008—for the first time in history—more people were living in urban than in rural areas. Today, more than one billion people live in slums. Founded by a collective of slum dwellers and concerned professionals headed by Jockin Arputham, a community organizer in India, Slum Dwellers International works to have slums recognized as vibrant, resourceful, and dignified communities. SDI organizes slum dwellers to take control of their futures; improve their living conditions; and gain recognition as equal partners with governments and international organizations in the creation of inclusive cities. With programs in nearly 500 cities, including more than 15,000 slum dweller-managed savings groups reaching one million people; 20 agreements with national governments; and nearly 130,000 families who have secured land rights, SDI has been a driving force for change for slum dwellers around the world.
