'Analysis of age-pyramids for human population can provide important inputs for long-term planning strategies.' Explain.

Analysis of age pyramids for human population can provide important inputs for long-term planning strategies. The different age groups present in a population determine its reproductive status. Distribution of age groups highly influences the growth of the population. Each population displays following three ecological ages or age groups:

1. Pre-reproductive 

2. Reproductive 

3. Post-reproductive 

Population having large number of young members grows rapidly, while, the population having more number of post-reproductive members tends to be declining. There are basically three types of age pyramids they are as follows:


Therefore, through the thorough analysis of the age pyramids of a particular population, the distribution of resources can be done more efficiently. A better planning strategy can be adopted considering the demand of the resource; thus, long-term management of resources can be done in such a way that the population can derive maximum benefit with minimum effects on nature, leading the population to flourish efficiently.
