This study aimed to analyze the multiple characteristics of the decentralization of the Brazilian National Food and Nutritional Security System (SISAN) in a period before the institutional dismantling. Data from the 26 Brazilian states were collected in two public information systems, referring to the years 2017/2018. An exploratory and descriptive study was performed using a hierarchical cluster analysis, based on an analysis model with multiple characteristics of the system decentralization. The results indicated the formation of three clusters, showing the similarity among states with greater intersectoral and participatory character, better relationship with municipalities, and allocation of resources. On the other hand, states with less intersectoral and participatory character, linked to the low allocation of resources, execution of food security actions, and municipal support were clustered. These clusters composed mainly of North and Northeastern states, with a lower Gross Domestic Product, average Human Development Index, and a higher occurrence of food insecurity, expressed characteristics that may be related to greater obstacles in the system decentralization process. This information can help in the decision-making about the SISAN in a more equitable manner, supporting the actors involved in its maintenance and defense, at a time when the country presents an austere political and economic situation, marked by the progressive worsening of food insecurity.
