Answer
No. The vertical axis does not start at 0. So, the height of the bars do not correspond to the "real" proportions.
Work Step by Step
- In the graph:
The height of the first bar (1992): $\approx0.202-0.170=0.032$
The height of the second bar (2004): $\approx0.1805-0.170=0.0105$
$percentual~decrease=\frac{0.032-0.0105}{0.032}\approx0.67=67$%
- The correct reduction:
1992 proportion: $\approx0.202$
2004 proportion: $\approx0.1805$
$percentual~decrease=\frac{0.202-0.1805}{0.202}\approx0.106=10.6$%
