Corruption costs the world economy $2.6 trillion each year, according to the United Nations, which is marking International AntiCorruption Day on Sunday.
"Corruption is a serious crime that can undermine social and economic development in all societies. No country, region or community is immune," the United Nations said.
The cost of $2.6 trillion represents more than 5 percent of global GDP.
The world body said that $1 trillion of the money stolen annually through corruption is in the form of bribes.
Patricia Moreira, the managing director of Transparency International, told VOA that about a quarter of the world's population has paid a bribe when trying to access a public service over the past year, according to data from the Global Corruption Barometer.
Moreira said it is important to have such a day as International AntiCorruption Day because it provides "a really tremendous opportunity to focus attention precisely on the challenge that is posed by corruption around the world."
To mark the day, the United States called on all countries to implement their international anticorruption commitments including through the U.N. Convention against Corruption.
In a statement Friday, the U.S. State Department said that corruption facilitates crime and terrorism, as well as undermines economic growth, the rule of law and democracy.
"Ultimately, it endangers our national security. That is why, as we look ahead to International Anticorruption Day on Dec. 9, we pledge to continue working with our partners to prevent and combat corruption worldwide," the statement said.
Moreira said that data about worldwide corruption can make the phenomena understandable but still not necessarily "close to our lives." For that, we need to hear everyday stories about people impacted by corruption and understand that it "is about our daily lives," she added.
She said those most impacted by corruption are "the most vulnerable people � so it's usually women, it's usually poor people, the most marginalized people in the world."
The United Nations Development Program notes that in developing countries, funds lost to corruption are estimated at 10 times the amount of official development assistance.
What can be done to fight corruption?
The United Nations designated Dec. 9 as International AntiCorruption Day in 2003, coinciding with the adoption of the United Nations Convention against Corruption by the U.N. General Assembly.
The purpose of the day is to raise awareness about corruption and put pressure on governments to take action against it.
Tackling the issue
Moreira said to fight corruption effectively it must be tackled from different angles. For example, she said that while it is important to have the right legislation in place to curb corruption, governments must also have mechanisms to enforce that legislation. She said those who engage in corruption must be held accountable.
"Fighting corruption is about providing people with a more sustainable world, with a world where social justice is something more of our reality than what it has been until today," she said.
Moreira said change must come from a joint effort from governments, public institutions, the private sector and civil society.
The U.S. Statement Department said in its Friday statement that it pledges "to continue working with our partners to prevent and combat corruption worldwide."
It noted that the United States, through the U.S. Department of State and U.S. Agency for International Development, helps partner nations "build transparent, accountable institutions and strengthen criminal justice systems that hold the corrupt accountable."
Moreira said that it is important for the world to see that there are results to the fight against corruption.
"Then we are showing the world with specific examples that we can fight against corruption, [that] yes there are results. And if we work together, then it is something not just that we would wish for, but actually something that can be translated into specific results and changes to the world," she said.
