What are the list of output for wbIncome Level metric?

The World Bank Income Level (wbIncome field on BigDataCloud API) is a classification system used by the World Bank to categorise countries based on their level of income and economic development. The system is based on a country's Gross National Income (GNI) per capita, which is the total income earned by a country's residents divided by the total population.

The World Bank groups countries based on their income level into four categories:

1. Low income: countries with a Gross National Income (GNI) per capita of $1,035 or less in 2021.
2. Lower-middle income: countries with a GNI per capita between $1,036 and $4,045 in 2021.
3. Upper-middle income: countries with a GNI per capita between $4,046 and $12,535 in 2021.
4. High income: countries with a GNI per capita of $12,536 or more in 2021.

This income classification is used by the World Bank to determine eligibility for loans, grants, and other financial assistance, as well as to provide insights into the economic development of different regions and countries.
