Determine the level of mechanical growth of the country according to the following data: the population is 4,073 thousand people, the birth rate is 47 thousand people, the death rate is 54 thousand people, 126 thousand people arrived, 94 thousand people left.
1) Find the mechanical gain: MP = I – E
126 – 94 = 32 thousand people
2) Determine the share of mechanical gain by making the proportion:
31 thousand people – X%,
X = 7.8%
Answer: The rate of mechanical population growth is 7.8%.
