## What is Palma ratio?

The Palma ratio is a measure of inequality. It is the ratio of the richest 10% of the population’s share of gross national income (GNI) divided by the poorest 40%’s share.

## How do you calculate income inequality ratio?

A simple but effective way to examine income inequality is to calculate decile ratios. The calculation is done by taking, for example, the income earned by the top 10% of households and dividing that by the income earned by the poorest 10% of households.

What is the 90 50 ratio?

A common measure of inequality in earned incomes is the P90/P50 ratio: the ratio of the earnings of the 90th percentile (the earnings which only 10% exceed) to the 50th percentile or median earnings. The higher this ratio is the more unequal earnings have become.

What is a percentile ratio?

Percentile ratios indicate the ratio of incomes of two persons who are at different positions in the disposable income distribution. The P90/P10 ratio compares the income at the 90th percentile to the one at the 10th percentile while the P50/P10 uses accordingly the 50th percentile in the numerator.

### How do you interpret Palma ratio?

The Palma ratio is an alternative to the Gini index, and focuses on the differences between those in the top and bottom income brackets. The ratio takes the richest 10% of the population’s share of gross national income (GNI) and divides it by the poorest 40% of the population’s share.

### What is quintile ratio?

It is calculated as the ratio of total income received by the 20 % of the population with the highest income (the top quintile) to that received by the 20 % of the population with the lowest income (the bottom quintile). All incomes are compiled as equivalised disposable incomes.

What does a 90 10 ratio of 1 mean?

A 90/10 ratio of five means that the richest 10% of the population earn five times more than the poorest 10%. The higher the ratio, the higher the inequality between these two points in the distribution. 90/10 ratio = the ratio of Decile 10 income to Decile 1 income.

What does a high 50 10 ratio Mean?

50/10 ratio – describes inequality between the middle and the bottom of the income distribution. 90/10 – describes inequality between the top and the bottom. 90/50 – describes inequality between the top and the middle. 99/90 – describes inequality between the very top and the top.

#### What does a low 90/10 ratio Mean?

Specifically, this research focuses on the 90/10 income inequality ratio—the wage or salary income earned by individuals at the 90th percentile (those earning more than 90 percent of other workers) compared to the earnings of workers at the 10th percentile (those earning higher than the bottom 10 percent).

#### Is there a 100th percentile?

The 100th percentile is defined to be the largest value in the list, which is 50. The 100th percentile is defined to be the largest value in the list, which is 20. So the 25th, 50th, 75th and 100th percentiles of the ordered list {3, 6, 7, 8, 8, 10, 13, 15, 16, 20} using the nearest-rank method are {7, 8, 15, 20}.

Is it better to be a higher or lower percentile?

If you know that your score is in the 90th percentile, that means you scored better than 90% of people who took the test. for example, the 70th percentile on the 2013 GRE was 156. That means if you scored 156 on the exam, your score was better than 70 percent of test takers.
