Definition: Age that divides the population in two parts of equal size, that is, there are as many persons with ages above the median as there are with ages below the median.
age distribution, also called Age Composition, in population studies, the proportionate numbers of persons in successive age categories in a given population.
Look to the person on your left. Now look to the person on you're right. According to data released Thursday by the U.S. Census Bureau, it's more likely that one of these people is 26 years old than any other age.
It is common in demography to split the population into three broad age groups: children and young adolescents (under 15 years old) the working-age population (15-64 years) and. the elderly population (65 years and older)
A human being's age can be categorized into four types: Chronological age, Appearance age, Biological age, and Mental age.
Some age-related development periods and examples of defined intervals include: newborn (ages 0–4 weeks); infant (ages 1 month–1 year); toddler (ages 1–2 years); preschooler (ages 2–6 years); school-aged child (ages 6–12 years); adolescent (ages 12–18 years).
Definition: Average age of the population calculated as the arithmetic mean. Another parameter determining the average age of the population is the median age. High-level terms.
The mode is the most commonly occurring value in a distribution. Consider this dataset showing the retirement age of 11 people, in whole years: 54, 54, 54, 55, 56, 57, 57, 58, 58, 60, 60.
What are the 5 age groups?
- Newborn [newborn] Up to 3 months old. Newborn sizes are often identified by the age range in months (0–3) or just “newborn.”
- Infant [infant] 3–12 months old. ...
- Toddler [toddler] 1–5 years old. ...
- Kids [kids] 5–13 years old. ...
- Adult [adult] Typically teens or older.
There are generally three types of population pyramids created from age-sex distributions-- expansive, constrictive and stationary.

- Finite Population.
- Infinite Population.
- Existent Population.
- Hypothetical Population.
According to recent research, global consumers aged 20 to 29 are the biggest users of social media—not entirely dissimilar to social media age demographics in the US. Those in this age group make up nearly one-third (32.2%) of all social media users worldwide. Of these users, the majority are male.
The majority of gamers in the United States are adults, and only 21% of them are under 18 years old. Among the adult crowd, people between the ages of 18 and 34 make up the majority. Still, senior gamers are a significant demographic, too: 15% of American gamers are older than 55.
A new survey finds most Americans believe the “sweet spot” in life is right in the mid-30s. A poll of 2,000 people finds four in 10 would not go back to their 20s.
Our current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%).
An age group is the people in a place or organization who were born during a particular period of time, for example all the people aged between 18 and 25.
Middle Childhood (9-11 years of age)
What is age 30 called?
A person between 20 and 29 is called a vicenarian. A person between 30 and 39 is called a tricenarian. A person between 40 and 49 is called a quadragenarian. A person between 50 and 59 is called a quinquagenarian.
Preschoolers (3-5 years of age).
As for what determines a person's rate of biological aging, Milman said genes play a role. There are certain "longevity genes" that can help shield people from environmental stressors, to a degree.
They found that genes have a lot to do with looking young. There are thousands of genes in everyone's DNA that focus on cell energy, skin formation, and antioxidant production, but "ageless" people express them differently, and often for longer while others peter out as they age.
The United Nations Convention on the Rights of the Child defines child as, "A human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier.” This is ratified by 192 of 194 member countries.
