In Area O, there will be more savers than spenders. Old people have usually accumulated more wealth and usually tend to have it in more conservative investments (i.e. fixed income instruments), whether they be bank deposits, bonds, etc.
In Area Y, people will have more desire to borrow, in order to buy homes, start businesses and (unfortunately) consume at a greater rate than they can afford.
