When people say "the West", they're usually referring to the more developed countries. It's a common misconception to automatically assume that all countries in Europe or North and Central America are developed: such countries, and even regions, of these continents are very deprived. I would say: France, Germany, Switzerland, Belgium, United Kingdom, Republic of Ireland, United States of America, Canada, Greenland, Spain, much of Italy, etc. The reason why I've put a statement about deprived countries on is because the people from the Eastern side of the world tend to be quite poorer, and look at our standard ways of living; therefore, the location is not the only important factor: the wealth, the society, the standard way of living, is what you would generally look for to define a "Western Country".
