Conversely, authors such as Barro (2000) and Lopez (2004) do not find any relationship whatsoever between inequality and economic growth and maintain that investment levels do not significantly depend on inequality. Some income inequality data for Brazil between 1995 and 2009 are shown in table 2. These data are the Gini index, the ratio between the income of the richest 10% and the poorest 40%, the ratio between the income of the richest 20% and the poorest 20%, the ratio between the income of the richest 10% and the poorest 10%, the average per capita household income and the percentage of people below the poverty line. The ratios of the incomes of the richest 10% relative to the poorest 10% and of the richest 20% relative to the poorest 20% also declined significantly during the period, especially the former, which moved down from 67.0 to 43.8. Meanwhile, per capita family income grew by approximately 22.5%. The last column shows that the proportion of people below the poverty line stabilized at around 19%.
