Vedclass · Answer

(A) In an age pyramid,a broad base indicates a high proportion of young individuals (pre-reproductive age),which signifies a rapidly growing population. Pyramid $B$ has a very broad base compared to pyramid $A$,indicating that $B$ represents a population with a higher growth rate (an earlier stage of demographic transition). Pyramid $A$ has a relatively narrower base,indicating a reduction in the proportion of young individuals,which suggests that the population is moving towards a more stable or slower growth rate (a more modern stage). Therefore,$A$ represents a more modern population structure compared to $B$.
