The number of people 65 or older expected to require nursing care is projected to grow by more than a fifth by fiscal 2025 to about 7.7 million, a tally based on prefectural data shows.

In fiscal 2025, social security costs are expected to grow sharply as the postwar baby boomers — the nation's biggest age demographic — form a stratum of people 75 or older. Those needing care as certified by their municipal governments stood at about 6.29 million in December.

The tally compiled and released by Kyodo News on Sunday thus says those needing nursing care will rise by 22 percent.
