From the data provided, China's undernourished population is on a decreasing trend over the five-year forecast period from 2024 to 2028. In 2023, the population stood higher than in 2024, but a consistent decline is forecasted. The percentage decrease year-on-year shows negative growth, illustrating an improvement in food security. The compound annual growth rate (CAGR) over this period reflects a sustained average reduction in undernourishment each year.

Future trends to watch for:

Continued policy efforts towards improving agricultural productivity and food distribution systems.
Impact of economic growth and urbanization on food accessibility and affordability.
Potential external factors such as climate change affecting food supply stability.
