Compared to the older, rudimentary programmes introduced in the region in the past, CCTs are better funded by the State and assure a greater coverage of the vulnerable population (Cornia and Martorano, 2010). Indeed, flagship programmes such as Bolsa Familia in Brazil and Oportunidades in Mexico now cover about 25 per cent of the population and cost on average less than 0.5 per cent of GDP (ERD, 2010). Most of the existing CCTs in the region require households to fulfill conditions linked to both educational attainment by children and regular health check-ups (Fiszbein and Schady, 2009). A more recent development of CCTs in the region is represented by the Red Solidaria in El Salvador, which - as well as offering transfers in exchange for education and health facility attendance - also provides a supply-side component to strengthen access to basic services, including investments in electricity, water, sanitation and other infrastructures (Britto, 2007).
