Aging is a natural, lifelong process that starts at conception and concludes with death. Growing older and maturing is connected to aging. As a result, we have all aged since our birth [1] . Population aging is occurring around the globe at different rates. Regardless of a country’s degree of development, the share of the population aged 60 or over is predicted to rise significantly globally [1] . Longer lifespans and falling fertility rates together cause aging [2] . Education and technological advancements, as well as improvements in medical, food distribution, and public health, all played a role in people living longer [3] . On the other hand, as people age, their physical and cognitive abilities deteriorate and the prevalence of chronic diseases and disabilities rises [4] .

Individuals 60 years and older are considered older people in Nepal [5] . In the last couple of decades, the life expectancy of the Nepalese is increasing rapidly [2] [6] and the elderly population growth rate is higher than the total population growth rate [2] . A report shows that it is projected to increase rapidly in the coming days further [7] .

In Nepal, the family serves as the primary caregiver for its elderly members, assisting them with daily tasks and providing them with various forms of support [2] [8] [9] [10] . The latest situation shows traditional norms and values eroding [9] due to shrinking family size and increasing migration of youths for looking prosperous future. This article aims to analyze the aging trends and situation of older people in Nepal using the 2021 census data of Nepal.

This Paper has utilized the 2021 census data of Nepal and past data published by the Central Bureau of Statistics of Nepal [11] . Further, many published articles focusing on issues of older people from Nepal including the author himself are included. Past and present data on fertility, mortality, life expectancy, aging index, proportion, and population growth rate are utilized to discuss in this paper.

In Nepal, older populations are increasing rapidly [2] [12] [13] and show a tendency that will further increase in the coming days as well [7] . Studies show older persons have a low immune system and are vulnerable to different types of diseases with increasing age [14] . With the rapid increase of older people Nepal may face challenges in social, demographic, economic, health, and care of older people in the coming days.

During the 1950s, life expectancy of Nepal was quite low (about 28 years) due to a high infant mortality rate and high crude death rate. However, a continuous decrease in the infant mortality rate has led to an increase in the life expectancy of Nepalese newborn babies [4] [13] . Consequently, during the second half of the 20th century, life expectancy in Nepal increased from 27 to 60 years and now it is expected around 70 years [6] . In other words, a Nepalese baby born in 2021 has a life expectancy of more than 40 years greater than one born 65 years earlier. Advances in health care, access to antibiotics, and improved nutrition during the twentieth century all may have contributed to this improvement.

In Nepal, the family, as a social institution, is the main source of support and care for its older members, helping them with day-to-day activities and giving them all kinds of support [8] [15] . Most Nepalese people follow the Hindu religion. Nepali Hindu society, like Indian Hindu society, is structured partly by the notion of life that has four stages (ashramas) and that life is driven by four goals: Brahmacharya (sexual abstinence or the life of a student), Grihastha (Marital life or householder), Vanaprastha (life in the jungle) and Sannyasa (asceticism). Each life stage prepares for the next stage, with the final goal of attaining redemption, moksha, from the cycle of rebirth. In the fourth and final stage of life, sannyasa, an individual is expected to sever all worldly ties in order to realize full inner spirituality [9] [16] . Hinduism contributes to the Nepali value system through the goal of Dharma. Dharma means duty and refers to the responsibilities a person has in his everyday life according to his place in the life cycle [9] [17] . The values of Hinduism are embedded in everyday life. Knowledge of customs and norms and compliance with these traditions is expected not only by family members but by the surrounding community as well [9] [16] [18] .

Decreasing fertility is not taken seriously by Nepali policymakers. The latest estimates show that the TFR of Nepal is below the replacement level of fertility. Studies from many countries show that once fertility reaches below replacement level naturally fertility starts to decline. It may indicate that the child population will start to decline now. The population pyramid of Nepal also indicates that the child population is decreasing rapidly compared to two decades ago. Further different measures of the older population also indicate either aging is taking rapidly or in a state to take place rapidly. As the proportion of older people is increasing and the out-migration of the younger population is increasing rapidly, Nepali older people may face some challenges taking the traditional care system [7] [8] [19] .

Increasing life expectancy is also associated with increasing different types of diseases in later years of life [14] . Different studies from Nepal show Nepalese older people have problems with loneliness [20] , depression [21] , sleep disorder [22] , functional disability [4] [19] [23] , elderly abuse [24] [25] [26] , and suffering from different chronic diseases [27] [28] and older people have a low quality of life [29] [30] . Having different types of health problems is associated with an increasing tendency of functional limitations in activities of daily living. It will increase the caregiving burden of older people [19] .

On the other hand, the traditional living system of the Nepali elderly is also started to change [31] . The living arrangement of the elderly in Nepal is contingent on their level of support [2] [10] [15] . In particular, the availability of care from a spouse or child may be essential to the well-being of the very old or frail elderly [32] . The older people depend on their children, particularly sons, for support and security in their old age in Nepal. The latest community study from Nepal shows the highest proportion of older people were living with Son/daughter-in-law (66.3%), followed by 11.6% living with a spouse, 6.2% living alone, 6.1% with a daughter/son-in-law, 4% unmarried son/daughter, 2.3% with grandchildren, 1.4% brother/sister-in-law, 1.3% with other family members and 0.9% others. It shows the majority of older persons were living with family members (81.3%), followed by spouses (11.6%), alone (6.2%), and others (0.9) [31] . Further, as the social security system of Nepal is not well developed [15] [33] Nepal may face further problems to maintain the healthy aging [34] [35] quality of life of Nepalese older people [29] [30] [36] .

In recent decades, fertility and mortality are decreasing rapidly in Nepal. On the other hand, the proportion of older people is increasing rapidly. The total fertility rate of Nepal is below the replacement level and is expected to fall further in the coming days. The average family size is decreasing and traditional living arrangements and caregiving systems are also in crisis due to the migration of young people. The caregiving burden of older people is expected to increase in the coming days. Nepal needs to formulate some policies on how to care for older people can be provided so they can live healthy and quality of life in the coming days.
