Please include documentation and copies of any additional datasets you end up using for your EDA below.

Analysis

Start by creating a table that plots country populations over time for subsets (of your choice) of the years and of the countries. Get the country names from the codes table.

Formulate a question about world populations and create a plot or set of plots that helps you find an answer to your question. Include a statement of your initial question, the plots and their descriptions, and a conclusion you’ve drawn from your exploratory data analysis.

Conclusion

Discuss your conclusions with respect to the question you formulated.
