Poverty gap index¶
The poverty gap index is a measure of the degree of poverty in a country.
Core Idea¶
Poverty gap index is treated here as the recurring formal models and representations identity summarized by this source-grounded definition: The poverty gap index is a measure of the degree of poverty in a country. The poverty gap index is a measure of the degree of poverty in a country. It is defined as "extent to which individuals on average fall below the poverty line, and expresses it as a percentage of the poverty line.". The poverty gap index is an improvement over the poverty measure head count ratio, which simply counts all the people below.
Scope of Application¶
-
Significance. The most common method measuring and reporting poverty is the headcount ratio, given as the percentage of the population that is below the poverty line.
-
Features. The poverty gap index is an important measure beyond the commonly used headcount ratio.
-
Features. In other words, the index can be used as an aggregate poverty measure, as well as decomposed for various sub-groups of the population, such as by region, employment sector, education level.
-
Related measures. The terms used to calculate W are same as in poverty gap index (see the calculation section in this article).
-
Significance. For example, The New York Times in July 2012 reported the poverty headcount ratio as 11.1% of American population in 1973, 15.2% in 1983, and 11.3% in 2000.
Clarity¶
A clear use of Poverty gap index names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is The poverty gap index is a measure of the degree of poverty in a country. The strongest recognition evidence in the frozen account is: If you multiply a country's poverty gap index by both the poverty line and the total number.
Manages Complexity¶
Poverty gap index compresses multiple formal models and representations details into a stable diagnostic relation. The source shows both the central mechanism—in other words, the index can be used as an aggregate poverty measure, as well as decomposed for various sub-groups of the population, such as by region, employment sector, education level, gender, age, or ethnic group.—and the practical consequence—the most common method measuring and reporting poverty.
Abstract Reasoning¶
- Type the carrier. Identify the formal models and representations entities to which the claim applies.
- State the relation. Use the source-grounded identity: The poverty gap index is a measure of the degree of poverty in a country.
- Check operation and conditions. It is calculated by averaging the square of the poverty gap ratio.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Poverty gap index transfers literally when a new case preserves the same carrier type, relation, and recognition test. The most common method measuring and reporting poverty is the headcount ratio, given as the percentage of the population that is below the poverty line. The poverty gap index is an important measure beyond the commonly used headcount ratio. Beyond the home domain. Transfer the broader Measurement relation when the formal models and representations-specific differentia cannot be filled.

Neighborhood in Abstraction Space¶
Poverty gap index sits in a sparse region of the domain-specific corpus (67th percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
