Most developed countries currently experience a reverse of the population pyramid to different degrees. That is to say, the birth rate is declining and the population is aging. People live longer and have less children; there’s not much we can do about it except hope for change. I know I’m definitely not part of the solution: over 30, no kids — heck, not even married. But hey, I’m not going to talk about me.
Even within this global context, Japan is a special case. We need to talk about a super aging population. Indeed, Japan holds the world record of aged population (65 and over) with 24.1% of the total population in 2012. And projections show that number reaching 38.8% by 2050. That’s more than one third of the population!
The speed of this aging of the population is also much faster than European or North American countries. For example, in the 24 years between 1970 and 1994, it nearly doubled (7.1% to 14.1%). In comparison, Italy took 61years to reach that level; Sweden, 85; and France, 115!!!
It wouldn’t be too bad if that were the only problem. But let’s take a look at the declining birth rate. In 2012, the child population (14 and under) in Japan was at an all time low of 13% of the total population. Need I say that this is the lowest level on record! You know your country is in deep shit when the number of elderly beats that of children by almost 2 to 1.
Not that Canada is the best example, but just to compare, Canada records 16.5% for child population and 14.2% for aged population, a ratio of 0.86.
As I wrote at the beginning, two factors that are stated for this situation in Japan is the increase of average maternal age at childbirth from 25.6 in 1970 to 30.3 in 2012, and the sharp increase in life expectancy after WWII. I’ll try to post some graphs tomorrow.
