Halo Mr. Sholihin,
First, don't forget to attach image for your essay.
:)
In introduction, I think you should use comma (not the semicolon)
Also, it will better if you give the overview of the data.
Here, some corrections :
s highest than canada's annual income
.
"$" written before the number and use comma for hundred
Japan is 15760 $$15,760 while the Canada annual is only $11,100
I suggest you can write down in the word apps instead on this website directly.
Thank you
