Global Population Growth image - Coggle Diagram

- - - - Healthcare improvements are reducing the death rate by alot, which helps increase the population. Before, many people died before reaching the age when they could have children, limiting population growth. However, with better medical care, more people are surviving into the age of birth, meaning they can have children. As a result, with less early deaths and more people able to start families, the population is expected to continue rising in the future. This change not only impacts the number of people in the country but also contributes to a healthier society overall.
- - - - Japan has a population mostly made up of people aged 45 and older, which means there are many elderly people in the country. This age distribution contributes to Japan's low and declining population, as older people generally do not have children. In fact, Japan's fertility rate is around 1.4 children per woman, which is much lower than the 2.1 needed to keep the population stable. Additionally, many young people are choosing to focus on their careers instead of starting families, further decreasing the birth rate. As a result, Japan faces challenges due to its shrinking population and an increasing number of elderly people, which can impact the economy and social services.
    - - India has a large population of people aged 15 to 45, which is the age group that has the most children, making this one of the main reasons for the country's fast population growth. The fertility rate in India is about 2.2 children per woman, meaning families are having enough children to help the population. Additionally, improvements in healthcare, such as better hospitals and vaccines, have led to more babies surviving after birth, which lowers the infant mortality rate. As a result, more children are living to adulthood, and fewer people are dying young. These factors together help explain why India has one of the largest populations in the world and is expected to continue growing for many years.
