Among the CT programmes targeting poor households, the most generous is Oportunidades, which offers 17% of the average wage to about 5.8 million families. As a result of varying coverage and generosity levels, the total public spending on these programmes also varies greatly among countries. Source: OECD Secretariat based on various sources and years, see Annex 2.A4 in OECD (2011b). Among the CTs not targeting specifically the elderly, big programmes such as Oportunidades and Bolsa Familia have annual expenditures representing between 0.4 and 0.5% of GDP.
