This paper aims to investigate the existence of a relationship between the electoral performance of state deputies, presentation, and the direction of individual amendments to the state budget. For this, data were collected from the individual amendments to the budget of the Legislative Assemblies of Minas Gerais and Paraíba, in the last two Legislatures (2011-2014 and 2015-2018). From the data collected, it was identified the vote of each deputy in each municipality, and the direction of the amendments, then we produced maps to illustrate the electoral vote and the allocation of resources, which allow the characterization of types of "informal districts" where the vote of deputies is predominantly in groups of contiguous municipalities. Moreover, the statistical tests allowed to adopt and measure whether variables such as concentration and electoral dominance have statistical significance in the destination of the amendments, as well as whether the amendments have an impact on the electoral success of deputies.
