Residents of urban areas (OR = 134.9; 95%CI 78.0;233.2), Northeast macro-region (OR = 2.9; 95%CI 2.5;3.1), female (OR = 2.0; 95%CI 1.8;2.1) and age group 60 years or older (OR = 1.6; 95%CI 1,3;1,7) were factors associated with assistance benefits. Factors related to the area of residence, macro-region, sex and age group increased the chance of granting assistance benefits.
