Ethiopia's population was estimated at 51.7 million in 1990. According to the nation's only census, conducted in 1984, Ethiopia's population was about 42 million. But the census was far from comprehensive.
The 1983 census put the total population of Sudan (including present-day South Sudan) at 21.6 million, which has increased dramatically over the past twenty years. While Sudan creates many refugees, it also hosts a sizable refugee population with over 310,000 people seeking asylum or refuge in Sudan in 2007. Sudan's population growth rate has declined steadily for the past ten years with a current growth rate of 1.83%.
