Calculation for average annual economic growth rate:
Real per capita GDP in Singapore in 1957 was about $400 and it doubled to about $800.00 by 1979 over the period of 22 years.
Growth rate = [tex](\frac{last value}{initial value} )^{\frac{1}{n} } -1[/tex]
The last value = $800
The initial value = $400
n = number of years
Growth rate = [tex](\frac{800}{400} )^{\frac{1}{22} } -1[/tex]
= [tex](2)^{\frac{1}{22} } -1[/tex]
= 1.032 - 1
= 0.032
Growth rate % = 0.032×100
= 3.2%
