The second graph shows the growth from each period to the next. (The most recent period is the change from the first half of 2013 to the second half of 2013):
In this case, we also see a moderate change. From the first half of 2013 to the second half of 2013, the CPI rose 1.4 percent.
Within the index's component, found here, we see that the categories showing the largest increases in prices were energy and housing, with rent up 7.3 percent (year over year) and fuels and utilities up 13.7 percent over the same period. Division of Housing data showed a 6.4 percent increase in the average rent from the 4th Q of 2012 to the 4th Q of 2013.
Given that both are essential items, these increases can have a significant effect on household budgets.
