What is the equation for calculating a population size?
The equation for calculating population size can be represented as: [ P = P_0 + (B - D) + (I - E) ] where ( P ) is the current population size, ( P_0 ) is the initial population size, ( B ) is the number of births, ( D ) is the number of deaths, ( I ) is the number of immigrants, and ( E ) is the number of emigrants. This equation accounts for natural population changes and migration effects.
What does the term to foot a column mean?

Does population growth equal birth rate minus the death rate?
Yes and no. "Natural increase" is births minus deaths. "Population growth" includes immigration and emigration too! So populations can have a negative natural increase (more deaths than births) but still have population growth because immigrants enter the country and settle there permanently (migration). Case in point - the USA.
How is population growth measured?
It is calculated by using the Death rate and Birth rate to give an estimated population growth statistic. If there are more deaths than births there is a decline, and if there are more births than deaths then there is a population increase.
Who writes down the births deaths and vital statistics of a population?
A demographer
What does the population do when the number of births is greater than the number of deaths?
