how to identify birth rates and death rates through age pyramid?
Answers
Answer:
A population pyramid that has fairly straight sides (more like a barrel) shows a population with a falling birth rate and a rising life expectancy. Rapidly tapering top or concave slope suggests high death rate and low life expectancy. Over time, as a country develops, the shape changes from triangular to barrel-like
Explanation:
A population pyramid or "age-sex-pyramid" is a graphical illustration of the distribution of a population (typically that of a country or region of the world) by age groups and sex; it typically forms the shape of a pyramid when the population is growing.[1] Males are usually shown on the left and females on the right, and they may be measured by count 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.
