Visualise age pyramids


In this vignette, we are going to try to visualise the age pyramid for 9 Western Europe countries. The list of these countries is:

countries <- c("Portugal", "Spain", "Italy", "France", "Ireland", "Belgium", "Luxembourg", "Germany", "Switzerland")

We can get the contact data for all these countries in a single function call with:

age_data <- age_df_countries(countries)

For the visualisation itself, we use the graphical package ggplot2, which offers a large flexibility in terms of customisation:

ggplot(age_data, aes(x = population, y = age)) + 
  geom_bar(stat = "identity") +
  facet_wrap(~ country, scales = "free")
