This chapter seeks to provide an overview of what we know about urban poverty in low-and middleincome nations (for a more detailed coverage see Mitlin and Satterthwaite 2013). It draws on the
literature not only on poverty but also on deprivations associated with poverty in regard to housing
conditions, health, access to basic services, rule of law and voice. It suggests that the scale and depth of
urban poverty in Africa and much of Asia and Latin America is greatly under-estimated because of
inappropriate definitions and measurements. How ‘a problem’ is defined and measured obviously
inf luences how a ‘solution’ is conceived, designed and implemented − and evaluated. The use of
inappropriate poverty definitions that understate and misrepresent urban poverty helps explain why so
little attention has been given to urban poverty reduction by aid agencies and development banks. It
explains the paradox of so many poverty statistics apparently showing relatively little urban poverty
despite the evidence showing the very large numbers living in poverty and facing many deprivations.
