In this latest Middle East and North Africa edition of the Global Corruption Barometer we find that 50 million adults in the region are having to pay bribes to access the basic services that they need. This is one of the findings from our survey, which aims to give a voice to ordinary citizens' views and experiences of corruption and help hold governments to account for their actions – or lack thereof – at stopping public sector graft. For the survey we are in partnership with the Afro barometer and several national partners of the Arab Barometer network, which spoke to 10,797 adult respondents from September 2014 to November 2015 in nine countries and territories: Algeria, Egypt, Jordan, Lebanon, Morocco, Palestine, Sudan, Tunisia and Yemen.
