Introduction: Retirement is a process that can last up to a year. It consists of stages that must be passed in order for a person to qualify for a pension. It is usually accepted as an event that requires planning and some adaptation. It is considered a transitional phase of life due to its duration, which can be extended even up to several years, and various interventions are also present for the best possible adaptation to life in retirement. Methods: Based on the collected data, an analysis of the adjustment of the elderly to retirement was made. The satisfaction of pensioners in the Republic of Croatia was examined through a survey. The survey included questions of a sociodemographic nature and the Retirement Adjustment Questionnaire, authored by Zvjezdan Penezić. Results: The research shows that the majority of retirees are not satisfied with their financial situation in retirement and therefore look for additional sources of income. They are additionally worried about long waiting lists for medical examinations. Also, they believe that there should be more organized social events for retirees. Discussion:. The acute demographic situation in Croatia and Europe points to the fact that the number of elderly people is increasing. Due to the increasing number of elderly population, the number of people who belong to the status of pensioners is increasing. Most of the research shows that retirees are not satisfied with their financial status, and they have a great turnout at social events that include them and their peers, which is confirmed by this research.
