population assignment (what I learned)

Yesterday we had an assignment in class it was to go in CIA world fact book and find five countries and write facts about them that are relevant to what we have learned in class. Some of the things I learned were Eswatini is a country and its population is rising slowly and Germany's population is declining rapidly. Another thing I learned was Pitcairn Islands population is only fifty four people. I also learned that Costa Rica's population will rise in a few years and then fall back down. And the final thing I learned from this assignment was that Angola's birth rate is 43.7 births per 1,000 of the population.
