population pyramid:
This is the population pyramid for World. A population pyramid illustrates the age and sex structure of a country's population and may provide insights about political and social stability, as well as economic development. The population is distributed along the horizontal axis, with males shown on the left and females on the right. The male and female populations are broken down into 5-year age groups represented as horizontal bars along the vertical axis, with the youngest age groups at the bottom and the oldest at the top. The shape of the population pyramid gradually evolves over time based on fertility, mortality, and international migration trends.

2) The rank that you see is the CIA reported rank, which may habe the following issues:
a) They assign increasing rank number, alphabetically for countries with the same value of the ranked item, whereas we assign them the same rank.
b) The CIA sometimes assignes counterintuitive ranks. For example, it assigns unemployment rates in increasing order, whereas we rank them in decreasing order
