Žirmūnai is occasionally described as a "borough of elderly people" or even a "borough of elderly women". There is a certain statistical basis to the claim: according to the data of the April 2001 census, only about 43.5% of Žirmūnai's population were male, the second lowest percentage in Vilnius, after Žvėrynas (43.1%); 27.4% of the population (33.2% of women and 19.9% of men) were of legal retirement age, which was 57.5 years for women and 61.5 years for men at the time. This is the highest percentage in Vilnius; accordingly, Žirmūnai had the lowest percentage of residents that were statistically of working age (defined as over age 15 and up to the retirement age) in Vilnius, only 56.4% in total: 52.8% of women and 61.1% of men.
