- Prebirth: Potential – The child who has not yet been born could become anything – a Michelangelo, a Shakespeare, a Martin Luther King – and thus holds for all of humanity the principle of what we all may yet become in our lives.
- Birth: Hope – When a child is born, it instills in its parents and other caregivers a sense of optimism; a sense that this new life may bring something new and special into the world.
- Infancy (Ages 0-3): Vitality – The infant is a vibrant and seemingly unlimited source of energy. Babies thus represent the inner dynamo of humanity, ever fueling the fires of the human life cycle with new channels of psychic power.
- Early Childhood (Ages 3-6): Playfulness – When young children play, they recreate the world anew. They take what is and combine it with the what is possible to fashion events that have never been seen before in the history of the world.

The global population pyramid: How global demography has changed and what we can expect for the 21st century
In 1950, there were 2.5 billion people on the planet. In 2021, there were around 8 billion. By the end of the century, the UN expects a global population of around 10 billion. But how has the age structure of the world’s population changed over time? The following chart — the population pyramid — makes it possible to understand this enormous global transformation. Population pyramids visualize the demographic structure of a population. The width represents the size of the population of a give...
The median age provides an important single indicator of the age distribution of a population. It provides the age 'midpoint' of a population — where there are the same number of people who are older than the median age as there are younger than it. On the map, we see the median age in all countries in the world. Overall we see that higher-income c...
The age structure of a population has important impacts for various aspects of society: economic growth rates, labour force participation, educational and healthcare services, housing markets amongst others.2,3 Over the past century, the age structure of populations has been changing dramatically. In these two charts you can compare the population ...
The world population is changing: For the first time there are more people over 64 than children younger than 5
Countries across the world have been going through an important demographic transition: from young to increasingly aging populations. In 2018, the number of people worldwide older than 64 years old surpassed the number of children under 5 years old. This was the first time in history this was the case.4 We can see this transition clearly when we look at the population by age bracket in the chart — this is shown from 1950 onwards, with UN projections to 2100. In this chart, you can explore the...
It is common in demography to split the population into three broad age groups: 1. children and young adolescents (under 15 years old) 2. the working-age population (15–64 years) and 3. the elderly population (65 years and older) A large share of the population in the working-age bracket is seen as essential to maintain economic and social stabilit...
Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth (LEB, or in demographic notation e 0 , where e x denotes the average life remaining at age x ).
adulthood, the period in the human lifespan in which full physical and intellectual maturity have been attained. Adulthood is commonly thought of as beginning at age 20 or 21 years. Middle age, commencing at about 40 years, is followed by old age at about 60 years.

- Childhood (ages 0-12) Birth is a wonderful event for the parents but also comes with many responsibilities. Their impact is enormous throughout those early years of your life.
- Adolescence (ages 13-20) During the teenage years, you transition from being dependent to independent. While becoming more responsible for your actions, you still have a safety net.
- Early adulthood (ages 21-35) Adulthood comes in 3 stages, and complete independence characterizes the early stage. It’s also a time of high individuality, finding your place in society, and striving for personal success.
- Middle adulthood (ages 36-50) The next stage of life involves a transition to interdependence. While most people still aim for personal achievements, we enjoy it better if we can achieve success collectively.
How many periods or stages are on your list? Perhaps you have three: childhood, adulthood, and old age. Or maybe four: infancy, childhood, adolescence, and adulthood. Developmentalists often break the lifespan into eight stages: Prenatal Development. Infancy and Toddlerhood. Early Childhood. Middle Childhood. Adolescence. Early Adulthood.
