The paper presents statistical and spatial analysis of ageing of rural population in Mazovian Voivodship. The analysis using population statistics from the Central Statistical Office of Poland, carried out on a local LAU 2 level, where rural areas were defined according to DEGURBA classification, and using classical measures of ageing proves that all rural LAU 2s in the region are old by UNO criteria, however those adjacent to cities and Ostrołęka town are relatively younger. Population of Warsaw is older than population of adjacent rural communes. In case of rural LAU2s there is a strong correlation between the share of the old and Sauvy’s index, while there is no linkage between the share of old and double ageing index.
