Understanding Real GDP Per Person Growth Rate

The Real GDP Per Person Growth Rate is a crucial economic indicator that measures the change in the average economic output per individual in a country over a specific period, adjusted for inflation. It provides a more nuanced view of economic progress and living standards than simply looking at GDP growth alone, as it accounts for population changes and the erosion of purchasing power due to inflation.

What is Real GDP?

Gross Domestic Product (GDP) is the total monetary value of all the finished goods and services produced within a country's borders in a specific time period. Real GDP, however, is adjusted for inflation. This means it reflects the actual volume of goods and services produced, providing a more accurate picture of economic growth than nominal GDP, which can be inflated by rising prices.

What is GDP Per Person?

GDP Per Person (also known as GDP Per Capita) is calculated by dividing the total GDP of a country by its total population. This metric represents the average economic output per individual. While it's an average and doesn't reflect income distribution, it's a widely used indicator of a country's standard of living and economic productivity.

Why Calculate Real GDP Per Person Growth Rate?

Calculating the Real GDP Per Person Growth Rate helps us understand:

Improvement in Living Standards: A positive growth rate suggests that the average person is contributing to and benefiting from increased economic output, potentially leading to higher incomes and better quality of life.
Economic Efficiency: It can indicate whether an economy is becoming more productive relative to its population size.
Policy Effectiveness: Policymakers use this metric to assess the impact of economic policies on the well-being of citizens.

The calculation involves a few steps:

Calculate Real GDP Per Person for the Current Year: Divide the Real GDP of the current year by the population of the current year.
Calculate Real GDP Per Person for the Previous Year: Divide the Real GDP of the previous year by the population of the previous year.
Calculate the Growth Rate: Use the standard growth rate formula: ((Current Value - Previous Value) / Previous Value) * 100. In this case, the "Current Value" is the Real GDP Per Person for the current year, and the "Previous Value" is the Real GDP Per Person for the previous year.

The formula is:
Real GDP Per Person Growth Rate = [((Real GDP Current Year / Population Current Year) - (Real GDP Previous Year / Population Previous Year)) / (Real GDP Previous Year / Population Previous Year)] * 100

Example Calculation:

Let's say:

Real GDP (Current Year) = $21,000,000,000
Real GDP (Previous Year) = $20,000,000,000
Population (Current Year) = 15,000,000
Population (Previous Year) = 14,500,000

Step 1: Real GDP Per Person (Current Year)
$21,000,000,000 / 15,000,000 = $1,400 per person

Step 2: Real GDP Per Person (Previous Year)
$20,000,000,000 / 14,500,000 ≈ $1,379.31 per person

Step 3: Real GDP Per Person Growth Rate
( ($1,400 – $1,379.31) / $1,379.31 ) * 100
( $20.69 / $1,379.31 ) * 100
≈ 1.50%

In this example, the Real GDP Per Person experienced a growth rate of approximately 1.50%.
