Human Resources
People are a nation’s greatest resource. Nature’s bounty becomes significant only when people find it useful. It is people with their demands and abilities that turn them into ‘resources’. Hence, human resource is the ultimate resource.
What is Population?
A discrete assemblage of entities with identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population. It consists of a similar group of species who dwell in a particular geographical location with the capacity to interbreed. To interbreed, individuals in a population must be able to mate with other individuals in order to produce fertile offspring.
Not all individuals are able to survive and reproduce due to genetic variations in them.
A local population can be restricted to a smaller area or can occupy a larger area, making up for the entire species.
A metapopulation is when individuals in local populations scatter between other local populations.
Most of the populations are not stable due to various physical factors prevailing in the environment which act as limiting factors against exponential growth of the population.
A graph that displays the age-sex distribution of a country’s human population at a given frame of time is referred to as a population pyramid. It shows the variation in the population of the male and females with age that is otherwise (bar graphs) not feasible. It results in a pyramidal structure where the population is on the x-axis and age is on the y-axis.
