The standard of equal voting power calls for seats being evenly distributed between the constituencies. The Venice Commission has argued that equal voting power “cannot be separated from representativeness and, more broadly, from other aspects of equal suffrage which may impact the allocation of seats to constituencies.” Determining the constituency boundaries can give rise to marked “structural” inequalities in representation. These disparities, which can be caused deliberately or by haphazard, can be the result of either demographic change, gerrymandering, or “natural” gerrymandering.
