transparency international
Transparency International is a global body that measures corruption in countries and institutions, so citizens can see how honestly public money is handled.
In plain English
Chidinma runs a small provisions shop in Onitsha and every year she watches the same thing happen at the local council office. To collect a certificate that should be free, she has to slip something into an envelope first. She jokes with her neighbours that the envelope has become a tax nobody voted for, and everybody laughs because everybody knows it is true.
That calm, everyday frustration is exactly what Transparency International was built to track. It is an organisation, not a government agency, founded in Germany in 1993 by people who got tired of watching bribery decide who gets contracts, who gets released from custody, and who gets a plot of land approved.
Every year it publishes something called the Corruption Perceptions Index, which ranks countries by how corrupt their public sector is seen to be, based on surveys of business people and analysts. Nigeria usually sits low on that list, and the United Kingdom usually sits much higher, though it is not spotless either, especially when it comes to dirty money parked calmly in London property.
The organisation does not arrest anyone or freeze accounts. What it does is shine a light and keep score, which sounds small until you realise that light is often the only thing that makes powerful people uncomfortable enough to change.
Think about a Nigerian in Leeds sending ₦300,000 home for her mother's hospital bill. She trusts that the money reaches the hospital and not somebody's pocket along the way. Corruption is the invisible tax on that trust, and Transparency International's whole job is to make that tax visible.
If a country scores low on the Corruption Perceptions Index, foreign investors often demand higher returns before committing capital there, because they are pricing in the risk that contracts or court judgments might be calmly influenced by bribery rather than by the law.
Questions people ask
Is Transparency International a government body?
No, it is an independent, non profit organisation with chapters in many countries, including one in Nigeria, and it receives funding from governments, foundations and private donors while remaining separate from any single government's control.
How does the Corruption Perceptions Index actually work?
It combines several surveys and assessments from other respected institutions, asking business people, analysts and country experts how corrupt they perceive the public sector to be, then averages those views into a single score out of 100 for each country.
Why does Nigeria's ranking matter to an ordinary person's money?
A poor ranking signals to investors, lenders and trade partners that doing business may carry hidden costs from bribery, and those extra risks often translate into higher prices, scarcer jobs and slower growth for everyone, more than the people at the top.
