Abstract:

As a whole the discussions in group three gave the following conclusions: 1. Independent from the methods, the organisation is the main problem of a multi-country survey; 2. Coordination must be done from one central point. Identical-sampling, coding a.s.o. are problems of second order, solutions must be found from case to case;. 3. One point Group III missed in all the papers: that is discussion on the possibility and the necessity of the central databank with all "official figures" of all countries, with identical classification.
