Global Variables

Some things to note about this page

On Load, we change geo to province if it isn’t alread there,
We can just use the normal geo drowpdown because it is set to and will remain as Province, the other dropdown is basically just for display,
As a result, we can recycle a lot of the other dropdowns,
Probably the only other one we will overwrite is the map one, to instead display population data.
Also we add the age bracket dropdown
And we use a different measure and variable selection
It’s really just updated to display new data not change to much of the other variables and callbacks

Build callbacks to create interaction

Update the variable dropdowns based on the selection of the overall variable

Update the measure selection from Population Pyramid clicks
