The below Tableau Visualization took way longer than it needed to. The problem was the data source – this data is from the World Bank. When I download the data – all I wanted was a list of countries and populations. The population per year was a nice bonus. Mixed in with the countries were several regional and economic groupings that I didn’t really need or want, and there wasn’t a marker to filter them out. Then, adding all of the countries together didn’t equal the world total, which was odd. Spent a lot of time fishing to the data only to find out it doesn’t match on the World Bank website either.
