That is your definition. If you look at the Universal Declaration of Human Rights [1], the definition they employ is much broader. E.g.

  Article 25.
  (1) Everyone has the right to a standard of living adequate  for the health
  and well-being of himself and of his family, including food, clothing,
  housing and medical care and necessary social services, and the right to
  security in the event of unemployment, sickness, disability,  widowhood,
  old age or other lack of livelihood in circumstances beyond his control.
  (2) Motherhood and childhood are entitled to special care and assistance.
  All children, whether born in or out of wedlock, shall enjoy the same social
  protection.
