Calculate the number of emigrants in a population when the absolute growth was +140 and there were 400 births, 210 deaths, and 70 immigrants.

Question

Accepted Answer

∻Answer∻ ⚹ The number of emigrants is 120. ⚹ ∻Solution∻ ‖ a ⋮ Calculate the net population change: The absolute growth is given as +140. This means the population increased by 140 individuals. ‖ ‖ b ⋮ Determine the natural increase: The natural increase is the difference between births and deaths. $$ \text{Natural Increase} = \text{Births} - \text{Deaths} = 400 - 210 = 190 $$ ‖ ‖ c ⋮ Calculate the net migration: The net migration is the difference between immigrants and emigrants. Since the absolute growth is the sum of the natural increase and net migration, we can set up the equation: $$ \text{Absolute Growth} = \text{Natural Increase} + \text{Net Migration} $$ $$ 140 = 190 + (\text{Immigrants} - \text{Emigrants}) $$ $$ 140 = 190 + (70 - \text{Emigrants}) $$ $$ 140 = 260 - \text{Emigrants} $$ $$ \text{Emigrants} = 260 - 140 = 120 $$ ‖ ∻Key Concept∻ ⚹ Emigration calculation ⚹ ∻Explanation∻ ⚹ The number of emigrants is determined by considering the absolute growth, natural increase, and net migration.
