"Population ageing is an increasing median age in a population because of declining fertility rates and rising life expectancy."
This type of demographic history looks at changes in the age distribution of a population, including factors such as the number of elderly citizens, the age at which individuals marry and have children, and the age at which individuals retire.
Demographics: The study of population statistics, including age, gender, race, and other characteristics.
Life expectancy: The average age to which a person is expected to live, which has increased significantly over the last century.
Population aging: The process by which the proportion of older people in the population increases, often due to decreased fertility rates and increased life expectancy.
Gerontology: The multidisciplinary study of aging, including biological, psychological, and social aspects.
Age-related diseases: The increased likelihood of developing certain diseases, such as Alzheimer's and Parkinson's, as a person ages.
Elder care: The provision of care and support for older people, including home care, assisted living, and nursing home care.
Social security and retirement: Policies and programs designed to provide income and support for older adults, including social security benefits and retirement savings plans.
Long-term care: The provision of care and support for people with chronic illnesses or disabilities who need assistance with daily activities.
Aging and work: The challenges and opportunities faced by older workers in the workforce, including discrimination and ageism.
Intergenerational relationships: The relationships between people of different age groups, including grandparents, parents, and grandchildren.
Age-friendly communities: The design and implementation of communities that support and accommodate the needs of people of all ages, including older adults.
Healthy aging: The promotion of physical and mental health in older adults, including exercise, nutrition, and social engagement.
End-of-life care: The provision of care and support for people who are dying, including hospice care and palliative care.
Ageism: Discrimination and negative attitudes towards people based on their age, including stereotypes and prejudice.
The impact of technology: The ways in which technology can support and enhance the lives of older adults, including assistive and adaptive technologies.
