Write a note on population density and population pyramid
Answers
Answer:
A population pyramid, also called an "age-gender-pyramid", is a graphical illustration that shows the distribution of various age groups in a population(typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing.[1] Males are conventionally shown on the left and females on the right, and they may be measured by raw number or as a percentage of the total population. This tool can be used to visualize the age of a particular population.[2] It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species.
Explanation:
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit area, or exceptionally unit volume; it is a quantity of type number density. It is frequently applied to living organisms, most of the time to humans. It is a key geographical term.[1] In simple terms, population density refers to the number of people living in an area per square kilometre.
