Based on the census data, this paper estimates the O-D migration flow and migration rate between prefectures (cities) in China from 1995 to 2015. Applying the methods of GIS spatial analysis and social network analysis, this paper reveals the temporal and spatial variation characteristics of population migration in China in the past 20 years. It is found that: (a) China’s population migration has gradually moved from a relatively inactive “low activity era” with the participation of some regions to a relatively active “high activity era” with the participation of most regions. (b) The temporal and spatial evolution process of regional types of population migration shows the characteristics of continuous diffusion in active areas (cities) and significant reduction in inactive areas (cities). (c) The population migration network is bounded by the “Hu Huanyong line”, and the migration flows on the east and west sides are “dense in the east and sparse in the west” and have great gap. This spatial pattern has strong stability and tenacity. (d) Under the background of the continuous enhancement of population migration within the province, the “ebb and flow” of the attraction of the three coastal city agglomerations in the inter-provincial migration and the increasing attraction of the Southwest region, the flow field structure of population migration in the East, Central and West regions is as follows: the internal differentiation and influence scope of the main urban agglomerations in the coastal region are weakened; the Central region (except Hubei Province) has failed to evolve independent communities with provinces as units; in the West region, the Northwest is relatively stable and the Southwest is continuously changing.

The phenomenon of urban-rural inversion population aging is a severe issue faced by China in building a well-off society in an all-round way. Using GIS spatial clustering and multiple stepwise regression models, this paper analyzes the temporal and spatial evolution characteristics and driving mechanism of urban-rural inversion of population aging in China on a provincial scale. The results show that: 1) In terms of time series evolution, with the continuous higher level of China’s population aging, the phenomenon of urban-rural inversion is becoming more and more obvious. 2) In terms of spatial pattern evolution, from 1995 to 2018, the spatial agglomeration intensity of urban-rural inversion showed an inverted U-shaped change trend of “low—high—low”. It first appeared in the Eastern coastal areas, then gradually expanded to the Central and Western regions, and finally evolved into a national common phenomenon. 3) In terms of driving mechanism, there is a complex multi-dimensional and nonlinear interaction mechanism behind the phenomenon of population aging and urban-rural inversion. Among them, population and economic factors are the main driving factors of this phenomenon. For the western provinces with underdeveloped economy, serious population outflow and high level of rural aging, the phenomenon of “old and poor” in rural areas has become a key challenge in the implementation of strategies such as rural revitalization and targeted poverty alleviation.

This study aimed to compare internet use among African American older adults by gender and age group and investigate correlates of internet use by gender and age group. A total of 1117 African American older adults aged over 50 from the 2016 Wave of the Health Retirement Study were included in the study. Sequential ordinal logistic regressions were conducted to investigate correlates of internet use among older African Americans by gender and age group. Significant gender and age differences were identified in internet use frequency. Gender differences on correlates were revealed: being old-old and limitations on activities of daily living were only associated with decreased odds of more frequent internet use among women. In addition, higher depression was only associated with reduced odds of more frequent internet use among men. Age differences on correlates indicated that education and cognition were the only two significant factors pertinent to internet use among the old-old. By contrast, for young-old adults, retirement, poverty, education, cognition, and depression were also predictive. Practitioners should consider these gender and age differences when promoting internet use among older African Americans. The results presented in this study might also inform the design of future gender- and age-tailored interventions.

The purpose of this paper is to analyze the death rate of Mexican population from 1980 to 2015, and estimate the death rate according to the seven main causes of death in 2050. For this purpose, four data sources are used: Population and housing censuses, population and housing statistics and inter-country surveys (2015). In addition, specific rates of standardized mortality by age and sex were estimated, and death projections were calculated using gamma estimation. The results show that by 2050, the main cause of death will be non-communicable diseases, also known as chronic degenerative diseases. This may lead to increased economic expenditure on health care and increased adult care time. All of these may lead to changes in social roles and workload.

Through the construction of population actuarial model and parameter design, this paper studies the dynamic trend of China’s population structure development from 2018 to 2050 under the comprehensive two-child policy The study found that for every 0.1 increase in the total fertility rate under the comprehensive two child policy, the average annual growth rate of the total population will increase by 0.06%-0.07%, the average annual growth rate of population aging will decrease by 0.15%-0.19%, the average annual growth rate of the total dependency ratio will increase by 0.080%- 0.036%, the average annual growth rate of the elderly dependency ratio will decrease by 0.17%-0.23%, and the average annual growth rate of the child dependency ratio will increase by 0.09%-0.18%, The annual average decline rate of gender ratio between men and women will be reduced by 0.001% This shows that the increase of the total fertility rate under the comprehensive two child policy can significantly alleviate the decline rate of the total population, significantly improve the rising rate of China’s population aging, significantly reduce the rising rate of the elderly dependency ratio, but also significantly increase the rising rate of the total dependency ratio and the child dependency ratio, and significantly inhibit the decline rate of the gender ratio of men and women At the same time, even if every couple has two children from 2018 to 2050, China’s population change situation is still not optimistic Finally, based on the empirical results, policy suggestions are put forward.

The purpose is to analyze the level, trend and impact of external mortality in Colombia and Mexico from 1998 to 2015. The years of life loss of children under the age of 85 were calculated, and the trend was estimated by model regression analysis. These causes of death and age groups contribute to changes in life expectancy at birth. In Colombia, mortality from all analyzed external causes decreased significantly; in Mexico, the rising murder death rate and the rising suicide rate have reversed their downward trend. The mortality rate in Mexico is higher than that in Colombia, which clearly shows the different trends in the two countries.

Using the survey on aged population in urban/rural China from 2000 and 2010, we aim to achieve the following three objectives: First, to document the general trend in older adults’ worry about eldercare, their family relations, socio-economic resources, and the availability of community services; second, to assess if improving socio-economic resources and availability of community services reduce older adults’ worry about eldercare; and third, to examine if family relations are still important during such social changes. Results show that older adults’ improving socioeconomic conditions and expanding community services are associated with less worry about eldercare. Meanwhile, family relations, measured by the number of children, living arrangements, and children’s filial piety, remain important. Our findings demonstrate that while building social welfare programs, including providing community services, certainly alleviates older adults’ worry about eldercare; they are no substitute for family ties, which should be facilitated rather than overlooked by public policies.

Objectives: To determine the quality of life of the elderly in the social programs for the elderly in the two provinces of Ica, Peru in 2017. Methods: This is a non-experimental, descriptive and cross-sectional study. The population consists of the elderly in the provinces of Ica, Palpa (N = 65) and Nasca (N = 30) in Peru. The analysis unit is mainly the group of adult participants in the geriatric sociology project. The quality of life was assessed by SF-36 health questionnaire. Result: 90% of the elderly in Nasca province had a high-quality mental health life; And 60% people had a regular quality of life based on vitality. In the Palpa Social Gerontological Program, 81.5% of the elderly had a higher quality of life in terms of mental health, but a lower quality of life in terms of physical health (63.1%). Conclusion: The quality of life of the elderly in Nasca Social Gerontological Program is higher than that of the elderly in Palpa Gerontological Program.

Youth internal migration is seen as a solution to youth unemployment, and this has resulted in over urbanization and its associated negative effects such as congestion, pollution, unemployment, underemployment, and increased crime rates. The study aimed at examining the employment status of youth migrants, assessing the relationship between demographic factors and youth internal migration, investigating the association between socio-economic factors and youth internal migration, and evaluating the association between reasons for migration and migrant employment status. The study used secondary data collected in the youth employment and migration in Eastern and Southern Africa project. In Uganda, the project was carried out in nine districts. The study focused on both men and women aged 18-35 years and a total number of 1524 respondents were interviewed. Results of the study revealed that age, residence, and region had a significant association with migration status (p≤0.05). Age, sex, number of children, region, and reasons for migration had a significant association with self-employment status of the migrant (p<0.05). Marital status, sex, and reasons for migration had an association with the possibility of a migrant youth being employed (p≤0.05). The study recommends that local governments should provide the required infrastructures, social services, and amenities to encourage youths to carry out economic activities so as to develop their places of origin.

Based on the methods of the average period age ratio and the average cohort age ratio, this study systematically assesses age heaping or digit preference in all population censuses of China. Our study finds that the overall age heaping was relatively low in the Chinese censuses; however, there was a notable preference for ages ending with zero after age 50 in the first two censuses, despite a weakening trend over time. Our study further shows that age heaping in China’s censuses is likely associated with age-related policies such as those on late marriage and retirement. As shown in the study, the average age ratio method can be an alternative of the Whipple’s Index and be improved if the size of birth cohort was taken into account when the number of births is generally reliable.
