In 2023, the number of subcontracted employees in public health and hygiene in Japan was ideally established as a baseline, given the context. Forecasts for 2024 to 2028 indicate a stable yet modest increase from 2.44 thousand to 2.45 thousand persons. The year-on-year growth from 2024 to 2025 shows no percentage change, while from 2025 to 2026, there is a slight increase. When viewed across this five-year period, the compound annual growth rate (CAGR) conveys a negligible annual increase, reflecting stability in this sector's subcontracted workforce.

Future trends to watch for:

Any shifts in public health policies or hygienic concerns due to possible global pandemics or environmental changes.
Technological advancements impacting the demands for human labor in public health tasks.
Societal attitudes towards health and hygiene, potentially increasing the demand for such services.
