## 3 Results and Discussion  
Figures 1-4 show the results (maps) obtained using CA. Figure 1 shows maps related to the answers to questions about emptiness after the retirement (Appendix A, questions No. 21E and 18R). The structure of the maps for _males_ and for _females_ (top panels) are different. For _females_ (top right panel), the angles between the vectors CP-_employees_ and CP-_A4_, between CP-_retirees2_ and CP-_A2_ are small. Consequently, we can extract two clusters:  
* _employees--A4_,
* _retirees2--A2_. The lengths of all of the vectors CP-_employees_, CP-_A4_, CP-_retirees2_, and CP-_A2_ are large. Then, the two associations are strong. For _males_ (top left panel), the angles are nearly 180 degrees between vectors CP-_retirees_2 and CP-_A4_, between CP-_retirees_1 and CP-_A5_. Therefore, in this case, we have negative associations:  
* _retirees_2--_A4_,
* _retirees_1--_A5_. If the spread between the number of answers to different questions is large then the least common answers usually correspond to the negative associations. The least common answer about emptiness after retirement given by _retirees_2 is A4 \"I was not afraid\". The least common answer about emptiness after retirement given by _retirees_1 is A5 \"I was not afraid at all\". Depending on the lengths of the corresponding vectors, the strengths of the association may vary. In this case, the negative association for _males_ is weak since the lengths of these vectors are smaller than for _females_. The point representing _employees (males)_ is located close to the central point, so there are no strong associations of this group with any of the answers, while the most frequent answer for the _employees (females)_ is A4 \"I am not afraid\" (cluster _employees_--_A4_). Figure 1: Classification maps (questions No. 21E and 18R). Transition to retirement is a key moment when an individual must redefine his or her social roles, which is not always successful. Women more often define their social role as a family member: housewife and mother. After the end of their professional activity they find themselves in the role of grandmothers, participating in the family life of their children [51]. According to opinion polls in Polish society men are less involved in family life and performing household duties so after they terminate professional life they would stay without any activities and many of them may feel emptiness [52]. Figure 2: Classification maps (questions No. 15E and 15R). If we consider the marital status, we observe negative associations for _married_ (Figure 1, bottom left panel):  
* _employees--A1_,
* _employees--A2_,
* _retirees2--A4_,
* _retirees1--A5_. The angles between the vectors CP-_employees_ and CP-_A1_, between CP-_employees_ and CP-_A2_, between CP-_retirees2_ and CP-_A4_, and between CP-_retirees1_ and CP-_A5_ are close to 180 degrees. The least common answers for _employees (married)_ about emptiness after the retirement are A1 \"Yes, I am very much afraid\" and A2 \"Yes, I am slightly afraid\". The least common answer to this question of _retirees2 (married)_ is A4 \"I was not afraid\". The least common answer to this question of _retirees1 (married)_ is A5 \"I was not afraid at all\". As the lengths of CP-_A5_ and CP-_retirees1_ are smaller comparing to other vectors, the association for _retirees1_ is the weakest. Figure 3: Classification maps (questions No. 19E and 20R). For _others_ (Figure 1, bottom right panel), the structure of the map is different than for _married_. We observe different negative associations:  
* _employees--A5_,
* _retires2--A4_,
* _retires1--A2_. Analogously, as for _married_, the least common answer to this question of _retieves2 (others)_ is A4 \"I was not afraid\". The marital status is not an important factor determining the kind of answer to this question for _retieves2_. For _retieves1 (others)_ the least common answer is A2, whereas for married is A5. For _employees (others)_ the least common answer is A5, whereas for _employees (married)_ the least common answers are A1 and A2.
