Given the values provided:
Natality = 25
Mortality = 24
Immigration = 2
Emigration = 3
The net increase in population (M) can be calculated as follows:
M=Natality−Mortality+Immigration−Emigration
M=25−24+2−3
M=1+2−3
M=3−3
M=0
Based on the given values, the net increase in the population (M) is 0. Therefore, the correct option is (B) 0.
The population size of a village is influenced by several factors: births (natality), deaths (mortality), immigration (individuals entering the village), and emigration (individuals leaving the village). The net increase in population is calculated by considering all these factors.
We are given the following information:
The net increase in population (\(\Delta P\)) can be calculated as:
\(\Delta P = \text{Natality} - \text{Mortality} + \text{Immigration} - \text{Emigration}\)
Substituting the given values:
\(\Delta P = 25 - 24 + 2 - 3 = 0\)
Therefore, the net increase in population is:
0
