  Taking a spacetime average as a measure of the strength of singularities we
show that big-rips (type I) are stronger than big-bangs. The former have
infinite spacetime averages while the latter have them equal to zero. The
sudden future singularities (type II) and $w-$singularities (type V) have
finite spacetime averages. The finite scale factor (type III) singularities for
some values of the parameters may have an infinite average and in that sense
they may be considered stronger than big-bangs.
