Political instability and corruption
Nigeria's large population and historic ethnic instability has led to the adoption of a federal government.  The resultant fiscal decentralisation provides Nigeria’s state and local governments considerable autonomy, including control over 50% of government revenues, as well as responsibility for providing public services.  

The lack of a stringent regulatory and monitoring system has allowed for rampant corruption.  This has hindered past poverty alleviation efforts to a large extent, since resources which could pay for public goods or directed towards investment (and so create employment and other opportunities for citizens) are being misappropriated.

Nigerian corruption and poverty are interrelated and encourages each other. WhenAs the first plane carrying Syrian refugees arrived in Toronto, Canadians were on hand to welcome them to their new country.
