EDITORIAL: Chronic Kidney Disease and the Aging Population

The proportion of older people in the general population is steadily increasing worldwide, with the most rapid growth in low- and middleincome countries.

However, population aging also has important implications for society—in diverse areas including health systems, labor markets, public policy, social programs, and family dynamics. A successful response to the aging population will require capitalizing on the opportunities that this transition offers, as well as effectively addressing its challenges.
