What is the average Gini coefficient?
The World Bank’s estimate of the Gini Index for the US was 41.1, and China at 42.1, both slightly higher than the average among all countries of 38.8.
What is the HDI of Sierra Leone?
0.452
Sierra Leone’s HDI value for 2019 is 0.452— which put the country in the low human development category—positioning it at 182 out of 189 countries and territories.
What is Niger’s HDI?
Niger’s HDI value for 2019 is 0.394— which put the country in the low human development category— positioning it at 189 out of 189 countries and territories.
What is Gini coefficient by country?
The ratio of the average income of the richest 20% to the poorest 20%. Gini. Gini index, a quantified representation of a nation’s Lorenz curve. A Gini index of 0% expresses perfect equality, while index of 100% expresses maximal inequality….Key:

What percentage of Sierra Leone is poor?
Approximately 60 percent of Sierra Leoneans live below the national poverty line. Remaining among the world’s poorest nations, ranking 180 out of 187 countries in the Human Development Index, more than 60 percent of Sierra Leoneans live on less than $1.25 a day.
Why is Sierra Leone HDI so low?
Why does it have a low HDI? Sierra Leone has a low HDI mainly because of it’s high unemployment rates and very low literacy rates. The average life expectancy of a person from birth is only to about 34 years of age.
Why is Nigers HDI so low?
Due to the effect that economies can often suffer from the “snowball” effect, the fact that two-thirds of the nation live below the poverty line of making less than $1 a day, Niger’s low HDI is a direct result from poor healthcare, a meager economy, and a lack of centralized, nationalized infrastructure.
Why does Chad have a low HDI?
A low old age dependency ratio of 5.5%, shows Chad’s low life expectancy, which helps distinguish Chad’s inadequate standards of living and overall status as a developing country.
What is a bad Gini index?
Gini index < 0.2 represents perfect income equality, 0.2–0.3 relative equality, 0.3–0.4 adequate equality, 0.4–0.5 big income gap, and above 0.5 represents severe income gap. Therefore, the warning level of Gini index is 0.4.
What is the Gini index and Gini coefficient?
Gini Index. The Gini Index is a summary measure of income inequality. The Gini coefficient incorporates the detailed shares data into a single statistic, which summarizes the dispersion of income across the entire income distribution.
What is the difference between Gini coefficient and perfect equality?
The Gini coefficient and other standard inequality indices reduce to a common form. Perfect equality—the absence of inequality—exists when and only when the inequality ratio, , equals 1 for all j units in some population (for example, there is perfect income equality when everyone’s income equals the mean income ,…
Does Gini index have a downward-bias?
Gini index has a downward-bias for small populations. Counties or states or countries with small populations and less diverse economies will tend to report small Gini coefficients. For economically diverse large population groups, a much higher coefficient is expected than for each of its regions.
How does granularity affect Gini coefficient?
Gini coefficients and income mobility. As with other inequality coefficients, the Gini coefficient is influenced by the granularity of the measurements. For example, five 20% quantiles (low granularity) will usually yield a lower Gini coefficient than twenty 5% quantiles (high granularity) for the same distribution.
