Differentiate between Expansive and stationary population histograms.

Expansive and stationary population histograms illustrate different demographic trends.

1. Expansive Population Histogram:

   • This type of histogram typically shows a population with a high birth rate and a high proportion of young individuals.
   • The histogram will have a broad base indicating a large number of individuals in the younger age groups (children and young adults), tapering off as age increases.
   • Characteristics include a pyramid-like shape, reflecting a population where births exceed deaths, leading to a growing and youthful demographic profile.
   • Countries with expansive populations often experience rapid population growth and face challenges related to providing education, healthcare, and employment opportunities for the large younger population.

2. Stationary Population Histogram:

   • This histogram represents a population where birth rates have declined and are relatively equal to death rates, resulting in a stable population structure.
   • The histogram will have a more uniform distribution across age groups, showing similar numbers of individuals in each age bracket.
   • Characteristics include a rectangular shape or column-like structure, signifying a balanced population with steady proportions of young, middle-aged, and elderly individuals.
   • Countries with stationary populations typically have lower fertility rates and longer life expectancies, leading to an aging population and potential challenges related to healthcare and pension systems.

In summary, expansive population histograms depict a youthful and growing population, whereas stationary population histograms indicate a more balanced and stable population structure with implications for social and economic policies.
