Final answer:
The chart referred to as Figure A7 illustrates the world's population distribution by country, with bars indicating the population size in millions of the 12 most populous countries as of 2015.
Step-by-step explanation:
The chart described as Figure A7, titled Leading Countries of the World by Population, 2015, showcases the world's population distribution by country. In this bar graph, each bar represents one of the 12 countries with the largest populations, and the height of each bar indicates the size of that country's population in millions.
This type of graph is commonly used in the field of Geography to visually represent population sizes and facilitate comparison between different countries.
Analyzing population data is essential when discussing topics like population characteristics, predicting future population trends, and understanding the impact of physical or human factors on demographic changes, as referred to in standards such as WG.7A, WG.7C, WG.9A, WG.13B, and WG.14B.
For example, when one compares population size with net population growth rate, regions like Africa, which have a high net population growth rate according to Figure 3.13, can be identified as key focal points in the discussion of global population dynamics.
