Answer:
False
Explanation:
The consumer price index (CPI) is calculated by using a basket of goods, not all the goods and services produced in the year.
The CPI formula = (current price of CPI basket / base period's price of CPI basket) × 100
When we compare current CPI with last year's CPI we can calculate the inflation rate for the year.
The GDP deflator is also used to calculate the inflation rate. The main difference with the CPI is that the CPI might include foreign goods while the GDP deflator doesn't include foreign goods. Usually the deflator and the CPI are the same, but theoretically they could be different, but in general practice they are not.
