How the 2018 AARIA was Calculated

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

  • 2017 Nova Scotia Consumer Price Index: 132.4
  • 2016 Nova Scotia Consumer Price Index: 130.9
  • 2015 Nova Scotia Consumer Price Index: 129.3

To calculate the percent change for 2016:

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

To calculate the percent change for 2017:

132.4 – 130.9 = 1.5
1.5 ÷ 130.9 = 0.011 = 1.1%

To calculate ARRIA for 2019:

(1.2 + 1.1) ÷ 2 = 1.2%
