This report deals primarily with the numbers and characteristics of visitors to the Oosterhof shopping center. An important subject is also the nature of the visit, i.e. which stores were visited, what was the main purpose, what kind of articles were bought. In addition, attention is paid to the scope of the shopping center and to traffic production. Finally, spending in the center is converted into purchasing power flows, both from the origin areas in the area and from the shopping areas of withdrawal.
