Inga was born in Ólafsfjörður as the second of four children. For the first two years of her life, Inga was blind after suffering damage to her brain stem due to incorrect medication taken after contracting chickenpox and meningitis.[2] In her adulthood, Inga is legally blind with 10% of her vision remaining. Inga was raised in an impoverished family, and has stated that her political beliefs are influenced by this upbringing.[3]
Inga founded the People's Party in 2016, a populist political party intended to advocate for Icelanders who "have suffered injustices, differences, lawlessness and poverty".[6] The party has been cited as syncretic, with left-wing stances on disability rights and poverty, and right-wing stances on other issues such as immigration.[7] As a politician, Inga has described herself as a populist and compared herself to the French politician Marine Le Pen.[8]
