Suburb and outskirts какая разница?? Не мону понять разницу

The suburbs — территория города вне центра, которая однако находится в черте города. I live in the suburbs of St. Petersburg, at the metro station of Bolshevikov Prospekt.

Explanation:

The suburbs are the part of the town or city lying outside the main central section (where most shops, public buildings, etc. are likely to be concentrated). It is a neutral term, and does not really have any qualitative or judgemental connotation. Willesden or Balham are suburbs of London.

The outskirts — территория за чертой города, окраина. There are some nice new houses in the outskirts of Tver.

Explanation:

Outskirts generally means the outer fringes of a town or city — i.e. only the outermost part of the suburbs, possibly the last straggling parts of the urban area before it becomes the country. London is a poor example to choose, inasmuch as it more or less melds imperceptibly into surrounding towns, but one might say that Richmond for example (a town in its own right) lies on the outskirts of London (note also the different construction)
