The elaboration contains a detailed description of the population and households by source of maintenance, in conjunction with demographic and socio-economic characteristics, including disabled persons and households with disabled persons, based on the results of the National Population and Housing Census 2011. It should be stressed that responding to questions on disability was carried out on a voluntary basis. Data from this area were derived by generalization of data collected in 20% of the sample (in the country) of people living or staying in randomly selected dwellings. In order to illustrate the changes occurring in the period between censuses basic information has been presented on the background of results of the National Population and Housing Census 2002.
