Introduction: Diets must meet energy needs and provide a diversified diet that can be consumed without risk. The objective of this work is to carry out a typology of urban household diets. It is a cross-sectional analytical study. Methods: The methodology consists of a food survey of 220 households. The data analysis was carried out on SPSS, R and Minitab software. Pearson's chi-square, PCA and CHA tests were performed. Results: The result revealed that the food products most stored by households are cereals (95.7%) and oils (75.2%). The average food diversity score of the surveyed households is high and based on the six food groups: cereals, vegetables, meat, oils/fatty products, sugar/sweet products and spices. The food consumption score shows that 85.7% of urban households have an acceptable food consumption and that the food groups that influence this score the most are vegetables, fruits, animal proteins, milk/dairy products, oils/fats and sugars/sweet products. Thus, the study resulted in four types of diets, based on their level of diversity and energy density. The first is a simple diet composed of foods that constitute the basis of the traditional diet in Niamey and the other three are modern mixed diets composed of processed and traditional foods (fat and sugar) heralding the nutritional transition at the household level. Conclusion: the study shows an association of diets with diversity and household food consumption.
