Seeing your difficult situation, I really want to help you, but it's too difficult. The key factor affecting the solvency of insurance companies is the adequacy of various reserves. Only when experts come to a conclusion can we judge whether the reserves are sufficient, and ordinary people in the industry have no say. Since you have chosen this topic, let's put aside the above factors and only analyze the data in the financial statements. I think you are no longer an amateur, but this can only be an analysis of individuals and can only be done. Also, you should get at least one financial statement of the insurance company. The financial statements of listed companies are disclosed to the public. Please look for it.
Another way is to change the title to "Investigation Report on the Payment Ability of Social Endowment Insurance". At present, there are so many discussions on the ability to pay pensions in society that there are many opinions on delaying retirement age. You might as well search and see that this topic should be much easier to write. The survey objects can be retirees or employees, and their income and payment can be investigated by age group. I hope it helps you.
