Describe the differences between the age structure graphs of non-
growing, slowly growing, and
rapidly growing countries.

The base of any age group graph represents a population below the age of fifteen. ... Thus, rapid growing graph has a wider base while a slow growing population has a narrower base. a steady population graph has base approximately equal to the population age group above it.
