C.pattern of population distribution in large urban areas.
D.it is the decadal growth of an area.

Answer 1

Hint: These graphs or parameters can also contain continuous histograms or or bar graphs. conventionally the mails are shown towards the left and the females are shown towards the right. The size and colour of each class is already decided. the measures or mathematical expressions like mean mode Central tendency cumulative frequency are considered while pictorially representing this pyramid.

Complete answer: Population pyramid, also called an "age-gender-pyramid". It is a graphical illustration or representation that shows the distribution of various age groups in an active population. It forms the shape of a pyramid when there is a growth in the population due to which it is known as the population pyramid. It can also be used to visualise the age of a particular age group. This pyramid also includes the reproductive capabilities of a certain age group and also their likelihood to continue the species. These graphs or parameters can also contain continuous histograms or or bar graphs. conventionally the mails are shown towards the left and the females are shown towards the right. The size and colour of each class is already decided. the measures or mathematical expressions like mean mode Central tendency cumulative frequency are considered while pictorially representing this pyramid.

Thus, Option A is the correct answer.

Note: There are three types of population pyramid. Stationery pyramid, expansive pyramid and constrictive pyramid. Each country has its own population pyramid based on its individual data.
