The map above looks at whether or not the majority of your country’s population is born in the 20th or 21st centuries as of January 1st, 2025.
The data is based on Median age data from the CIA Worldfact book.
Currently 56 countries & territories have a majority of people born this century, while 173 still have more people born in the 20th century.
You can see the full data, and when a country can expect to become majority born in the 21st century below:

However, I should note that the data for when your country will become majority born in the 21st century is probably overly optimistic for most countries.
I just took the current median age of the country in 2024 (latest data at time of publication) and added it to 2,000.
Therefore, tt does not account for the fact that many countries will continue to see their median population age increase, which in turn will push back the date when they become majority 21st century.
What do you think?
Jonathan Wadman says
Which date does this data assume for the start of the 21st century – 1 January 2000 or 1 January 2001?

1 January 2000
