The poverty threshold, or poverty line, is the minimum level of income deemed adequate in a given country. In practice, like the definition of poverty, the official or common understanding of the poverty line is significantly higher in developed countries than in developing countries.

The common international poverty line has in the past been roughly $1 a day. In 2008, the World Bank came out with a revised figure of $1.25 at 2005 purchasing-power parity (PPP).

Determining the poverty line is usually done by finding the total cost of all the essential resources that an average human adult consumes in one year. The largest of these expenses is typically the rent required to live in an apartment, so historically, economists have paid particular attention to the real estate market and housing prices as a strong poverty line affector.

Individual factors are often used to account for various circumstances, such as whether one is a parent, elderly, a child, married, etc. The poverty threshold may be adjusted each year.

Sonia Gandhi (born Antonia Edvige Albina Maino on 9 December 1946) is an Italian-born Indian politician and the President of the Indian National Congress, one of the major political parties of India. She is the widow of former Prime Minister of India, Rajiv Gandhi and belongs to Nehru–Gandhi family. After his assassination in 1991, she was invited by the Indian National Congress to take over the Congress but refused and publicly stayed away from politics amidst constant prodding by the Congress. She finally agreed to join politics in 1997; in 1998, she was elected as the leader of the Congress.

Since then, Sonia Gandhi has been the President of the Indian National Congress Party. She has served as the Chairperson of the ruling United Progressive Alliance in the Lok Sabha since 2004. In September 2010, on being re-elected for the fourth time, she became the longest serving president in the 125-year history of the Congress party. Her foreign birth has been a subject of much debate and controversy. Although Sonia is actually the fifth foreign-born person to be leader of the Congress Party, she is the first since independence in 1947.

Roaring Lion (born Rafael de Leon, Aroquita, Trinidad, British Trinidad and Tobago, 22 February 1908 – 11 July 1999^{[citation needed]}) was a calypsonian (calypso singer/composer). His 65-year career began in the early 1930s and he is best known for his compositions "Ugly Woman" (1933), "Mary Ann" and "Netty, Netty," which are still performed today.^{[citation needed]}

Rafael de Leon was born in Aroquita, in the Caura Hills of northern Trinidad, to a mother named Basalicion de Leon and a father named Arias Cairi Llama. An illegitimate child, Lion spent some of his earliest years in two orphanages, before being taken in, following his mother's illness, by an elderly woman named Miss Charles who lived on Coffee Street in the southwestern city of San Fernando. Finally, he was presented by Charles to a Muslim Indian^{[citation needed]} family in San Fernando who wanted him; he was adopted by Najeeran Khan, who became his adoptive mother. He championed orphanages throughout his career, with songs like 1940s "Orphan home" for one example. Although there has long been confusion about his full name, he himself gave it as Rafael Arias Cairi Llama de Leon. He later met his biological father, who told him that his name, Cairi, was another name for Trinidad, and that "Llama" is a sort of goat or deer from South America. In a 1990 interview, Roaring Lion stated that "from fear that I might be styled a thief, I only use Rafael Deleon."
