How Is the CPI Basket Chosen?
In deciding which goods and services to include
in the CPI basket and what their weights should
be, the ABS uses information about how much
– and on what – households in Australia spend
their income. If households spend more of their
income on one item, that item will have a larger
weight in the CPI. For example, the ABS included
smart phones in the CPI to reflect consumers
taking advantage of advances in technology. Data
on household spending across all items is only
available approximately every five years or so.
New products
The CPI does not include new products as soon as
they appear on the market. It can often take some
time until the ABS includes them in the CPI basket.
This typically occurs once a product has reached a
high enough market share and is available to most
households.
