HISTORY OF NIGERIA ECONOMY

  Nigeria is a middle income, mixed economy and emerging market, with expanding financial, service, communications, technology and entertainment sectors. It is ranked as the 21st largest economy in the world in terms of nominal GDP, and the 20th largest in terms of Purchasing Power Parity. It is the largest economy in Africa; its re-emergent
, though currently underperforming, manufacturing sector is the third-largest on the continent, and produces a large proportion of goods and services for the West African subregion. Nigeria recently changed its economic analysis to account for rapidly growing contributors to its GDP, such as telecommunications, banking, and its film industry.^[17]
Previously hindered by years of mismanagement, economic reforms of the past decade have put Nigeria back on track towards achieving its full economic potential. Nigerian GDP at purchasing power parity (PPP) has almost tripled from $170 billion in 2000 to $451 billion in 2012, although estimates of the size of the informal sector (which is not included in official figures) put the actual numbers closer to $630 billion. Correspondingly, the GDP per capita doubled from $1400 per person in 2000 to an estimated $2,800 per person in 2012 (again, with the inclusion of the informal sector, it is estimated that GDP per capita hovers around $3,900 per person). (Population increased from 120 million in 2000 to 160 million in 2010). These figures are to be revised upwards by as much as 80% when metrics are recalculated subsequent to the rebasing of its economy in April 2014.^[18]
Although much has been made of its status as a major exporter of oil, Nigeria produces only about 2.7% of the world's supply (Saudi Arabia: 12.9%, Russia: 12.7%, USA:8.6%).^[19] To put oil revenues in perspective: at an estimated export rate of 1.9 Mbbl/d (300,000 m³/d), with a projected sales price of $65 per barrel in 2011, Nigeria's anticipated revenue from petroleum is about $52.2 billion (2012 GDP: $451 billion). This accounts about 11% of official GDP figures (and drops to 8% when the informal economy is included in these calculations). Therefore, though the petroleum sector is important, it remains in fact a small part of the country's overall vibrant and diversified economy.
The largely subsistence agricultural sector has not kept up with rapid population growth, and Nigeria, once a large net exporter of food, now imports a large quantity of its food products, though there is a resurgence in manufacturing and exporting of food products. In 2006, Nigeria successfully convinced the Paris Club to let it buy back the bulk of its debts owed to the Paris Club for a cash payment of roughly $12 billion (USD).^[20]
According to a Citigroup report published in February 2011, Nigeria will get the highest average GDP growth in the world between 2010 and 2050. Nigeria is one of two countries from Africa among 11 Global Growth Generators Countries.
