To see this in the previous example (Table 1), imagine that Year 1, when total spending was $100, was also chosen as the base year, and given an index number of 100. For example, from period 2 to period 3, the overall change in the cost of purchasing the basket rises from $106.50 to $107. Mathematically, that is equivalent to dividing $107 by 100, or $1.07. Again, this is because the index number in the base year always has to have a value of 100. Which of these would most likely positively affect a nation's GDP?
