Pension system reforms refer to changes made to the way retirement benefits are structured, funded, and distributed, aiming to ensure sustainability and adequacy in the face of demographic shifts. These reforms often address challenges such as an aging population, increasing life expectancy, and a shrinking workforce, all of which impact the viability of traditional pension systems. By adjusting contribution rates, retirement ages, and benefit formulas, these reforms seek to balance the needs of retirees with the economic realities of a changing society.
