Household of retirees
Household whose exclusive or main (prevailing) source of maintenance is old age pension.
Additional sources of maintenance may include any other type of pension, other than pension unearned income (e.g. income from property, family benefits with supplements, gifts), hired work, a private farm in agiculture, self-employment outside a private farm in agriculture or free profession. The income gained from additional sources is lower than that from old age pensions and other types of pension.
