Participating households have been selected randomly, according to a statistical procedure designed to provide two representative samples of
i) all households in Luxembourg and
ii) all cross-border commuter households in the Greater Region.
Although participation in these surveys is voluntary, it is critical for the success of the surveys that the households contacted agree to participate in the survey.
The surveys contain two kinds of questions: some treat all household members as a single entity, and others are addressed separately to individual members of the household. Those concerning the household as a whole cover the following themes: real estate assets and their financing, other debts and credit constraints, private businesses and financial assets, intergenerational transfers (i.e. inheritances and gifts), consumption and saving. Questions concerning household members individually cover the following themes: demographics, employment, pensions and insurance policies and income.
