Population data and the percent change in population are two demographic measures that are great to look at for a variety of different reasons.
There are many different ways to visualize these two measures, depending what it is that you want to learn from this data or show to others in a presentation. In this post and in the video we demonstrate two different ways to do so using Tableau.
One way is to display the population data on a map. This is helpful especially if geography is important to what you are working on with this population data. For example if you are presenting different population sizes of different cities to a group of stakeholders who are not familiar with the locations of those cities or how far away or close to each other they are, then visualizing this on a map for them can help show this to them.
The percent change in population can also be visualized on a map. However, a better way to show percent change in population could be a bar graph.
The second way to display population data is with a bar graph, such as the bar graph shown in the video below for population change in 5 East Coast cities of Atlanta, Boston, New York City, Richmond (VA), and Washington D.C.
As you can see in the video, the interactive bar graph created using Tableau makes it easier to see which city had the greatest population change over the two five year periods looked at in this data set.
