The Ratio of CPI all-items to the equal weighted average of 5 items: rent, food, transport, childcare, energy.

When this goes down it means the 5 item index grows faster than the "overall average index" (ie. "families real needs becoming more expensive faster than the CPI suggests"). When it goes up it means that other expenses outside of family core needs go up faster.
