Recent years have witnessed fundamental changes in the financial and retail service sector,
with competition among companies intensifying as a result of changing markets. The need
to address the specific requirements of the customer groups has become the guiding
principle behind the business strategies adopted by companies. These customer needs
and, subsequently, the provision of the appropriate products and services to the customer,
are dependent on where they live, their personal characteristics (e.g., age, education,
income, households etc.). Geodemographic systems take advantage of information
technology to analyze these types of data for a better understanding of the consumer
characteristics and improved performing of marketing strategies. In the present study, a
geodemographic system is implemented utilizing geographic information systems (GIS)
technology and artificial intelligence (AI). GIS technology offers a powerful set of tools for
the input, management, and visualization of data, while AI provides advanced analytical
tools such as the unsupervised fuzzy classification through the Fuzzy C-Means algorithm.
The proposed methodology is applied to the Attica region in Greece. It uses the official
socioeconomic data of the Hellenic Statistical Authority. The relevant database uses 78
socio-economic variables. The study area consists of 2500 area units, each one with more
than 1000 inhabitants. The results, ten socio-economic classes, are analyzed and
discussed. The project is funded by the Athens Chamber of Commerce and Industry (ACCI)
and the results of the analysis are open to all users by the official site of ACCI.
