<s>[INST] context: Wealth index

The "wealth index" is a composite measure of the cumulative living standard of a household.
The wealth index is calculated using easy-to-collect data on a household's ownership of selected assets, such as televisions and bicycles, materials used for housing construction, and types of water access and sanitation facilities.
Information on the wealth index is based on data collected in the household questionnaire.

Second quintile

The distribution of the population across wealth quintiles show large variation across states : -


Delhi has maximum population in highest wealth quintile (70% of population).
