Standard Deviation & Standard Error (SD & SE)

The difference between the terms ‘Standard Deviation (SD)’ and ‘Standard Error (SE)’ may be confusing.
Both SD and SE are measures of variation but of two DIFFERENT factors. What are they?
Let us take an example:
We want to weigh a population of 10,000 workers in a factory.
The ideal way to do that would be to:
Weigh each one of the population of 10,000
Calculate the mean weight of the population i.e. Add up all the 10,000 weights and divide by 10,000.

Demographic cycle

Studying the world population since 1650 suggests that demographic transition of a nation involves of 5 stages.
These stages constitute the “demographic cycle”.
(1) FIRST STAGE (High stationary)
It is characterized by both
*A high birth rate and
*A high death rate
Therefore the population remains stationary
It is seen when the country is economically most weak
India was in this stage till 1920
(2) SECOND STAGE (Early expanding)
It begins with the
*Declining of death rate while
