Multi region/multi editable post/page template

Guys,
For a project, I will need to create pages, that will have different set of information, but each needs to be in its own “content area” and editable.

Does anyone here have a suggestion?

I made screenshot of how it should look.

Just imagine a page or post about “Brazil” and it has different sections like Economy, States, Population, each should be in its own box and editable separately. The same thing I’d have to repeat for other countries.

I hope you guys understand what I mean, see this picture:
