How to make a Population Pyramid Chart in Tableau?
Here we come with another short blog about how a population pyramid chart is made in Tableau.
To make a population pyramid chart, we have to take population data. Here we have population data of New Zealand. Our first step is to segregate Male and females from the Sex section. To do so follow the below steps:
On the left click on drop-down arrow and go to “Create Calculated Fields”
A dialogue box will appear where we will make a category of male and insert below formula “IF [Sex] = “Male” [Value] END” and click on Apply.
You will now see the Male tab on the left side under the Tables section. Duplicate this tab with the name Female and change the inner formula to this: “IF [Sex] = “Female” [Value] END” and click on Apply. Now you will see male and female tabs on the left.
Now we have male and female as two different categories now will drag age group into row self.
As we can see from the above data that there are a lot of values, we can filter these values and select specific age groups which we require for our analysis. To do so we will drag the age group section into the filter shown on the left, a list will appear in which we can check those we have to select.
Drag Male and female categories on Column self, two bar charts will appear.
To visualize this chart more accurately, we will click on the x-axis bar of male data and click on the edit axis and check the mark on reverse.
Now as you can see below, bar chart is now easy to read.
Now we have the population pyramid chart ready. We can filter data from the Tables sections to see the population of our required fields as having been added as shown below.
So, this is how you can easily calculate your required population using Tableau.
