Short Note

Describe steady population with the help of a pyramid.



When the pre-reproductive and the post-reproductive age groups in a population have almost the same number of individuals, then the population remains stable. This kind of population is called steady population. The young individuals in the age group of 0–14 years are proportional to the old individuals in the age group of 60 years and above.
