Population by age groups in the world

 

• <20 years: Approximately 2.6 billion people (33.2% of the global population) are under 20 years old.
• 20-39 years: Around 2.3 billion people (29.9%) fall within this age group.
• 40-59 years: About 1.8 billion people (23.1%) are between 40 and 59 years old.
• 60-79 years: Approximately 918 million people (11.8%) belong to this age range.
• 80-99 years: There are 147 million people (1.9%) aged 80 to 99.
• 100+ years: A smaller group, with 0.6 million individuals (0.01%), are 100 years or older.

Interestingly, our world now has a notably higher percentage of older people than it did 70 years ago. An aging population can have far-reaching consequences on a country’s economy, including workforce challenges and pension pressures. However, it also brings positive aspects, such as increased volunteerism and lower crime rates in older communities1.
