The basket is an average of the basket for successive pairs of years.

The technique is so named because the second number in a pair of successive years becomes the first in the next pair. The result is a "chain" of weights and averages. The advantage of using the chained-dollar measure is that it is more closely related to any given period covered and is therefore subject to less distortion over time.
