Likewise, in Sweden became the higher trend which contributes at 20% in 2010 but dropped to 17% in next decades, then it is estimated to soar and reached 25% in two decades later. Conversely, the figure of Japanese who aged 65 and over showed a substantial increase, beginning at 5% in around 2008 and it is calculated to rise and contributed the highest rate at 27% in 2040.
