The Dutch Government, before submitting their plans (policies) regarding Physical Planning to Parliament for approval, should give an opportunity to the people to react directly to these plans. The procedure followed is that of participation. One of the first subjects in which participation could have played a role in forming a central policy, was the urbanisation of the Netherlands. To help the participation procedure get under way, the Government conducted an informative campaign by means of the daily papers, the television and by radio. To establish the measure of effectiveness of this informative campaign, the Government decided to conduct a survey. After consideration it was decided to select an aim for the enquiry that would enable the fundamental variants concerning participation to be involved also. The research provided us with a number of results concerning public awareness of the campaign.
