economically less developed country
(ELDC)
  previously known as undeveloped, Third World, The South, less developed and less economically developed country (LEDC). A country whose development has yet to lead to the presence of welfare criteria that allow the country to be termed economically more developed. Terminology has changed to try and avoid unwarranted perceptions that people in different places may in some way be better than, or superior to, people in other places.
