Purpose The purpose of this paper is to gain a general holistic view of implications of the growing and highly relevant customer segment of elder consumers for the food demand chain (food retail, production, logistics, and business informatics) in Germany. Design/methodology/approach This paper takes a holistic demand-chain approach that is based on interviews with 36 German food consumers aged 65-87 and with 50 experts from manufacturing, trade, logistics, and business informatics as well as a survey with 1,288 consumers above 64 years of age and 682 consumers below 65 years of age. Findings Physical, statistical, psychological, social, and behavioural characteristics of elder German consumers may influence location, services, and layout of food retail, food variety, sizes, packaging, and labelling, food production, transportation, and storage volumes and capacities, as well as facility location, route, and inventory planning. The social function of grocery shopping especially for single consumers, intergenerational products and services, home-delivery services especially to rural areas, as well as decentralisation and regionalisation are expected to gain importance. Logistics and industry 4.0 can facilitate the efficient and effective supply of food. Originality/value This research is the first to investigate the needs and wants of elder German food consumers and their implications for the German food demand chain in a more holistic demand-chain approach.

Purpose Elder German grocery shoppers are a growing, heterogeneous, and highly relevant and attractive, but under-researched market segment. In order to understand them and their grocery shopping motivations better and target them efficiently and effectively, the purpose of this paper is to identify dimensions of their shopping motivations and segment them based on these dimensions. Design/methodology/approach In total, 26 grocery store-choice criteria were identified in a thorough literature review and focus-group interviews with 36 elder German consumers aged 65 and older. In a subsequent survey, the importance of these criteria was rated by 1,288 German shoppers of the same age group. A principal component and cluster analysis were performed to identify dimensions of store-choice criteria and segments of elder German grocery shoppers. Multivariate analysis of variance, analysis of variance and discriminant analysis were used to test for statistically significant differences between the clusters. Findings Basic quality considerations, shopping experience and social interaction, service and assistance, price consciousness, product orientation, convenient location and quick service and packaging requirements influence the grocery store choice of elder German consumers in decreasing order of variance explained. The cluster analysis revealed indifferent, leisure, convenience, assistance-oriented, no frills, product-oriented and service-oriented elder German shoppers, which differ in their shopping motivations statistically and significantly. These clusters are described and contrasted in detail to derive managerial implications. Originality/value This research provides the first store-choice component analysis and cluster analysis for elder German grocery shoppers. This can help food retail to reach this attractive target group more efficiently and effectively and improve the food supply of elder German consumers.
