Question

short note on population pyramid and sex ratio

Answer 1

Explanation:

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.

Sex ratio is the demographic concept that measures the proportion of males to females in a given population. It is usually measured as the number of males per 100 females. The ratio is expressed as in the form of 105:100, wherein this example there would be 105 males for every 100 females in a population.
