Is the placement of vapor barrier and/or air –water barrier to have continuous insulation outboard the same in all parts of the USA and World?

With no batt insulation in the studs and only an applied air/water barrier the thickness of ridged insulation is the largest changing factor. Dew Point Analysis will identify if the air – water barrier shall be permeable or not based on the climate and what side of the insulation it should be placed. Therefore that barrier acts as a vapor barrier as well in some climates.
