The survey findings indicate that Afghans consider corruption the third biggest problem in the country, following insecurity and unemployment, a ranking that has stayed the same since 2007. Corruption is widespread. One adult in seven, i.e. an approximate equivalent of 1,677,000 adults, experienced direct bribery in Afghanistan in 2009. 28% of Afghan households paid a bribe to obtain at least one public service. Furthermore, the Afghan experiences of bribery show that the amounts paid have considerably increased. In 2009, the average value of the bribes among those who paid them was 7,769 Afs (156 USD). This represents an enormous amount of money in a country where the per capita income is 502 USD per year. The survey indicates that the Afghan population as a whole paid twice as much in 2009 as it had paid in 2006. In 2007, the amount of bribes paid by the adult population was estimated at 466 million USD, while the current survey indicates that it is close to 1 billion USD. This also reflects the general perception about the impact of corruption on households. 34% of the respondents stated that the general effect of corruption on their households was considerable or extremely high, while 18% estimated that the financial burden on their households had increased in 2009 compared with 2008 due to higher bribe amounts.
