I want to know the answer to the following question:
What was Nigeria's population in 2009?
All the background I'm provided with is that "The United Nations estimates that the population in 2009 was at 154,729,000, distributed as 51.7% rural and 48.3% urban, and with a population density of 167.5 people per square kilometre.". Is that enough to answer the question?
Answer: yes
