Table 3.
Levels of, and changes in, Gini index for the eleven study countries (hypothesis: if income inequality influences suicide rates, rises in suicide rates will have occurred in countries with greater absolute, or increasing, income inequality)
| Country | Change in Gini index, 2004-2014a (rankc) | Gini index, 2008b (rankd) |

Countries where suicide rates are rising | ||
| Australia | +2.7 (2) | 35.4 (2) |
| Canada | +0.3 (7) | 33.8 (5=) |
| UK | -2.0 (9) | 34.1 (4) |
| USA | +0.5 (5) | 41.1 (1) |
|
Countries where suicide rates are not rising | ||
| France | +1.7 (3) | 33.0 (7) |
| Germany | +0.7 (4) | 31.2 (10) |
| Italy | +0.4 (6) | 33.8 (5=) |
| Japan | - | 32.1 (9) |
| Poland | -5.2 (10) | 33.5 (6) |

a
Due to restricted data availability, change in Gini calculated between the following dates for four countries: Canada, USA & Germany (2004-2013), Republic of Korea (2006-2012)
b
Due to restricted data availability, 2007 Gini index provided for Canada & USA
c
1=greatest increase in Gini index; 10=greatest decrease in Gini index
d
1=highest Gini index; 10=lowest Gini index
