Use World Bank data (http://data.worldbank.org/country) to describe the current trends in the
country/regions population (total, rural vs. urban, age and gender distribution using pyramids, etc.).
Describe the factors behind the population trends (births, deaths, migrations).
Describe the factors behind birth rates (fertility), death rates (diseases, nutrition, etc.), and
