How the 2018 AARIA was Calculated

To calculate the percent change in the Nova Scotia Consumer Price Index use:

  • 2016 Nova Scotia Consumer Price Index: 130.9
  • 2015 Nova Scotia Consumer Price Index: 129.3
  • 2014 Nova Scotia Consumer Price Index: 128.8

To calculate the percent change for 2015:

129.3-128.8 = 0.5
0.5 ÷ 128.8 = 0.004 = 0.4%

To calculate the percent change for 2016:

130.9 – 129.3 = 1.6
1.6 ÷ 129.3 = 0.012 = 1.2%

To calculate ARRIA for 2018:

(0.4 + 1.2) ÷ 2 = 0.8%
