Abstract This paper reports on the food-related lifestyle (FRL) segments identified in Ireland, based on a nationally representative sample of one thousand households. The objectives are to use the food-related lifestyle instrument developed by the Centre for research on customer relations in the food sector in Denmark (MAPP) to segment Irish food consumers based on attitudes towards the purchase, preparation and consumption of food products and to profile these segments by attitudes and socio-demographic variables. The sixty nine FRL items were scored and scale reliability tested. The structure of the FRL dimensions was tested with exploratory factor analysis using principal component analysis and varimax rotation. Hierarchical cluster analysis (HCA) using Wards method was employed for market segmentation. Profiles of the clusters (segments) were achieved by comparing the mean scores on the dimensions for each segment with the population mean scores on the same dimensions. Six distinct food-related lifestyle segments were identified. The hedonistic segment, representing 28 percent of consumers was the largest group, followed by conservative consumers (21%), extremely uninvolved consumers (16%), enthusiastic consumers (14%), moderate consumers (13%) and adventurous consumers (8%). The segments were found to have different attitudes towards food and different socio-demographic profiles.
