Writing assignment: "contrast"

This is my article that I wrote in a class last week.

▼The difference between living in a suburb and downtown.

Generally speaking, there are the two ways of living according to a resident's needs.
  I'd like to look at some differences between them. The first is about loudness.  As you know, it is always crowded downtown, so if noise is an issue, I advise you not to move there. On the other hand, a suburb is more or less quiet, except around the station.
The second difference is the convenience. Downtown, there are a variety of shops, from specialty shops to convenience stores.

When shopping for daily necessities, you are sure to find what you need, because everything is within walking distance.
Shopping in the suburbs is less convenient, because people usually live further away. To make matters worse, most shops in the suburbs close before night fall dusk.
The third difference is the cost between the two. If you live in the city, it is more expensive, simply because of the convenience of the location.

The third difference is about costs. If you want to live in the center of a city, you'll be surprised to know how expensive it costs you is to live even if you live in a far smaller than a room than you live in now because of its conveniently location and popularity.
That is to say, it's difficult for those who can't afford to pay to live near a downtown.
On the other hand, a city dweller can't believe other province's rent the rent in other places. Probably, especially for those who don't do so, living in a suburb is to theirs benefit to some extent.
In conclusion, because each of these ways has its merits and demerits, people can choose a suburb or a downtown depending on their situations and elements that they set a high value on.
