Rukia Rahmani, the general director of Mazandaran Welfare, wrote: Iran is on the brink of a great change. A change that may appear more than anything else in the country's demographic structure, but its effects go far beyond statistics and population numbers. The increase in life expectancy and the increase in the share of the elderly in the population means that Iranian society will face additional generations of elderly people in the coming years, and it is natural that many relationships, services and even the definition of our quality of life will have to undergo correction in the face of such a change.
