Population Profiles

http://www.japanfocus.org/-Roger-Goodman/2472

This is a population profile of Japan in 2003.   A population profile is represented in a chart (like the one above) and shows population growth rates in increments of four years from age 0 to 90.  Generally, population pyramids like the one above look more like a pyramid with a higher younger populations and decreasing populations with age.  However, Japan is a special case and has a more evenly distributed population with the exception of the age bracket from 30-50 years of age being the largest.  Japan's population is getting older and they are having less children which results in older average population.  The largest bracket is in the 50s range which is right after WWII, showing that there was an explosion of births during and after the war and then a sharp decline in the following years.
