What does it mean if a population pyramid has a wide base?

A population pyramid with a wide base indicates a high Birth Rate, suggesting that a significant proportion of the population is made up of children and young individuals. This demographic structure is often associated with developing countries, where higher fertility rates are common. Such a shape can imply future population growth, as the large youth cohort will eventually enter reproductive age. However, it may also reflect challenges in providing adequate resources and services for a growing population.
