Economic Growth can be defined as an increase in output produced by an economy in a period of time (usually a year) or an increase in the ability of an economy to produce goods and services. Economic Growth itself can be measured by measuring an increase in GDP, Real GDP (GDP adjusted for inflation), or Real GDP per capita (a measure of standard of living) which means the increase in real output per person.
Economists use real GDP per capita rather than simply real GDP. This is because population growth is an important variable (per capita), and so, real GDP per capita is the more accurate measurement of the GDP.
To find the rate of growth of per capita real GDP, you subtract the population growth rate from the growth rate of real GDP. In this case, 4% (real GDP growth) minus 1% (population growth) equals 3%. Therefore, the rate of growth of per capita real GDP is 3%.
The growth rate of real GDP per capita reflects changes in economic output relative to the population size. It equals the percentage change in real GDP minus the percentage change in population because it accounts for how much of the economic growth can be attributed to each individual in the population. Dividing would not accurately represent the relationship since it would imply an average rather than a per-person growth adjustment, failing to capture the effect of population growth on individual economic well-being. This subtraction effectively isolates the impact of population changes on real GDP per capita.
Real GDP per capita for the US is calculated by dividing the real Gross Domestic Product (GDP) by the total population. This measure provides an average economic output per person, reflecting the standard of living and economic productivity of the population. By adjusting for inflation, real GDP offers a more accurate representation of economic performance over time.
features of economic growth are 1.continues process 2.increse in per capita real income 3.long term process 4.quantative concept 5.no structual change 6.no solution to the problem
It can if your population increases faster than your GDP. Imagine if you have a 6% growth in GDP but a 10% growth in population => a reduction of 4% in GDP per capita.
