The article presents mathematical-economic methods for studying data on household consumption of four basic food products in Bulgaria for the period 2004-2020. The mentioned information concerning meat, yoghurt, potatoes and dry beans has been structured and saved in a built relational database. Certain sets of criteria are used to form queries from the database. Subsequently, the obtained information from the queries has been processed. The pace of growth, respectively decrease of the considered indicator for the listed products has been analyzed. Hierarchical cluster analysis has been applied to these data on household consumption, average per person. The results showed a relative increase of the indicator for two foods (meat and yoghurt) during the last five years of the period. The indicator values for potatoes declined significantly for 2012-2017. The same dependence has been established for dry beans from 2011 to 2015. Grouping the indicated foods according to the values of the household consumption shows two clusters. Three clusters are obtained by grouping the relevant years according to the values of this studied indicator.
