United Nations definition
In 2004, the United Nations sector of Economic and Social Affairs defined a homeless household as those households without a shelter that would fall within the scope of living quarters due to a lack of a steady income. They carry their few possessions with them, sleeping in the streets, in doorways or on piers, or in another space, on a more or less random basis.In 2009, at the United Nations Economic Commission for Europe Conference of European Statisticians (CES), held in Geneva, Switzerland, the Group of Experts on Population and Housing Censuses defined homelessness as:

In its Recommendations for the Censuses of Population and Housing, the CES identifies homeless people under two broad groups: (a) Primary homelessness (or rooflessness). This category includes persons living in the streets without a shelter that would fall within the scope of living quarters; (b) Secondary homelessness. This category may include persons with no place of usual residence who move frequently between various types of accommodations (including dwellings, shelters, and institutions for the homeless or other living quarters). This category includes persons living in private dwellings but reporting no usual address on their census form. The CES acknowledges that the above approach does not provide a full definition of the homeless.

The Universal Declaration of Human Rights defines homeless as those who do not live in a regular residence due to lack of adequate housing, safety, and availability. The United Nations Economic and Social Council Statement has a broader definition for homelessness; it defines homelessness as follows: When we are talking about housing, we are not just talking about four walls and a roof. The right to adequate housing is about security of tenure, affordability, access to services and cultural adequacy. It is about protection from forced eviction and displacement, fighting homelessness, poverty and exclusion. India defines homeless as those who do not live in census houses, but rather stay on pavements, roadsides, railway platforms, staircases, temples, streets, in pipes, or other open spaces. There are 1.77 million homeless people in India, or 0.15% of the countrys total population, according to the 2011 census consisting of single men, women, mothers, the elderly, and the disabled.
