Indeed, of the 20.2-percentage-point increase in aggregate household savings (as a share of GDP) in China from 1992 to 2009, the middle-aged cohort accounted for more than 60% (the remainder was largely attributable to the elderly). In the US, which experienced a 1.8-percentage-point decline in aggregate savings as a share of GDP, the savings-to-GDP ratio among the young declined by 1.25 percentage points, whereas the figure for middle-aged savers actually increased by about 1.5 percentage points.
事实上，在中国1992至2009年家庭总储蓄率（作为GDP的一部分）所增加的20.2%中，中年人群体占了超过60%（余下部分主要由老年人贡献）。在美国，在作为GDP一部分的总储蓄率下降的1.8%中，年轻群体中的储蓄/GDP比率下降了1.25%，而中年储蓄者的数据实际上是上升了大约1.5%。
