Final answer:
A true statement about global population and workforce changes is that the world's population will continue to grow due to the large base population, despite declining fertility rates. Aging populations present economic challenges as fewer young people can replace the retiring workforce. Immigration and demographic shifts will further impact labor markets and ethnic compositions of countries.
Step-by-step explanation:
A true statement about global population and workforce changes is that despite a marked decline in fertility and family size, especially in developing countries, the world's population is expected to grow significantly due to the compounding effect of a large existing population. This phenomenon means that even with lower growth rates, millions more people will be born, mainly because the base population is so large.
Furthermore, as people move from agricultural jobs to urban areas, the decline in birth rates in developing countries continues. Demographers anticipate a stabilization of the world's population by the year 2100, followed by a slight decline. As mortality rates have halved from 1950 to 2023, population aging is leading to an increased demand for medical and social services, thus impacting economic development and labor markets.
Changes in fertility rates and aging demographics are causing challenges in the workforce population balance. With fewer young people entering the workforce, there are not enough individuals to replace the aging population heading into retirement, particularly affecting manual labor sectors.
Migrations are also contributing to changes in regional population densities and the ethnic compositions of various countries. Immigration and birth rate variations among ethnic groups will significantly reshape societies. As European populations decline, there is a growing dependence on immigrants to fill entry-level jobs, which exemplifies the challenges of globalization and its effects on populations and economies.
In conclusion, population pressures and trends are intricately linked to socio-economic development, connectivity, and global resource management, presenting both challenges and opportunities for the future.
