The predictions tell planners how much infrastructure is required to support the population. Roads, water supplies, housing, police, fire, etc.

United States and Rwanda predict a slow but steady growth rate for the near future.

Birth Rates, Growth Rates, and Something else
There are several things that demographers use to predict how a population will grow. Some of them include gender balance, age, income levels and so much more.
The logistic growth model is a mathematical formula frequently used to predict population fluctuations in a community. It takes into account factors like carrying capacity and growth rate to model how a population grows over time.
The world is always changing. Technological advances help us live longer, but disasters such as earthquakes and hurricanes can lower our population. Humans are all over Earth, so it's hard to accurately predict our population.
A diagram of a population's age structure can help predict growth by showing the distribution of different age groups within the population. A pyramid-shaped diagram with a larger base indicates a younger population with high potential for future growth, while a more rectangular shape suggests a stable or declining population. This information helps in planning for future resource allocation, infrastructure development, and social services to support the population's needs.
The two major types of population models are deterministic models, which predict population changes based on fixed parameters and assumptions, and stochastic models, which account for randomness and variability in factors affecting population dynamics.
It is difficult to predict with certainty, but based on current trends and population growth rates, it is estimated that the global population may be around 10 to 12 billion people in 100 years. Various factors such as advancements in technology, healthcare, and social changes can also affect population growth.
Birthrates, Death Rates, and the age structure of a population help predict why some countries have high growth rates while other countries grow more slowly.
