Ethiopia has a population of over 96 million people and has never been colonized. The economy relies heavily on agriculture, which accounts for 46.3% of GDP. Inflation has been high, reaching 64.2% in 2008, though it has since fallen to 9.3% in 2015. The GDP was $46.87 billion in 2014, having grown from $7.27 billion in 1981. However, economic freedom remains limited and corruption is still prevalent. The government's main sources of income are taxes and its priority expenditures are on education, health, infrastructure and agriculture.
