The World Passport in this respect has a track record of over 60 years acceptance since it was first issued. Today over 185 countries have visaed it on a case-by-case basis. In short, the World Passport represents the one world we all live in and on.
Median age* of the population. Over the past 50 years, the median age of the world's population has increased by a mere three years, from 23.6 in 1950 to 26.4 in 2000. (The median marks the point where half the population is older than that age and half is younger). But over the next 50 years, the median age will jump to 37, according to the latest projections made by the United Nations. By 2050, 17 developed countries are expected to have a median age of 50 or more.
The most common age in America is now 22, according to the New York Times. Just as recently as 2010, the most common age was 50. Now, the tides have changed. In second and third place are 21 and 23-year-olds, with 53-year-olds in fourth place. For those that question the logic of growth, it's partly due to immigration, the report said. One might think that the size of any age cohort could only decline as it ages. Some people now 19 will die within the next year, and no new 20-year-olds will be born. But because of immigration, the Census Bureau says, most age groups up to about 40 years old are getting larger every year. As a result, the groups in their 20s are growing, while those of baby boom age are declining in size..
