I want to know the answer to the following question:
In 2001, what percent of Nigeria's population was Christian?
All the background I'm provided with is that "An 18 December 2012 report on religion and public life by the Pew Research Center stated that in 2010, 49.3 percent of Nigeria's population was Christian, 48.8 percent was Muslim, and 1.9 percent were followers of indigenous and other religions, or unaffiliated.". Is that enough to answer the question?
Answer: no
