Objectives: This study measures the average per person and annual total costs of dementia in England in 2015.Methods/Design: Up‐to‐date data for England were drawn from multiple sources to identify prevalence of dementia by severity, patterns of health and social care service utilisation and their unit costs, levels of unpaid care and its economic impacts, and other costs of dementia. These data were used in a refined macrosimulation model to estimate annual per‐person and aggregate costs of dementia.Results: There are around 690 000 people with dementia in England, of whom 565 000 receive unpaid care or community care or live in a care home. Total annual cost of dementia in England is estimated to be £24.2 billion in 2015, of which 42% (£10.1 billion) is attributable to unpaid care. Social care costs (£10.2 billion) are three times larger than health care costs (£3.8 billion). £6.2 billion of the total social care costs are met by users themselves and their families, with £4.0 billion (39.4%) funded by government. Total annual costs of mild, moderate, and severe dementia are £3.2 billion, £6.9 billion, and £14.1 billion, respectively. Average costs of mild, moderate, and severe dementia are £24 400, £27 450, and £46 050, respectively, per person per year.Conclusions: Dementia has huge economic impacts on people living with the illness, their carers, and society as a whole. Better support for people with dementia and their carers, as well as fair and efficient financing of social care services, are essential to address the current and future challenges of dementia.

Background: The number of older people with dementia and the cost of caring for them, already substantial, are expected to rise due to population ageing. Objective: This study makes projections of the number of older people with dementia receiving unpaid care or using care services and associated costs in England. Methods: The study drew on up-to-date information for England from multiple sources including data from the CFASII study, output from the PACSim dynamic microsimulation model, Office for National Statistics population projections and data from the MODEM cohort study. A simulation model was built to make the projections. Results: We project that the number of older people with dementia will more than double in the next 25 years. The number receiving unpaid or formal care is projected to rise by 124%, from 530,000 in 2015 to 1,183,000 in 2040. Total cost of dementia is projected to increase from £23.0 billion in 2015 to £80.1 billion in 2040, and average cost is projected to increase from £35,100 per person per year in 2015 to £58,900 per person per year in 2040. Total and average costs of social care are projected to increase much faster than those of healthcare and unpaid care. Conclusion: The numbers of people with dementia and associated costs of care will rise substantially in the coming decades, unless new treatments enable the progression of the condition to be prevented or slowed. Care and support for people with dementia and their family carers will need to be increased.

This paper examines the factors affecting the receipt of informal care among older people in China. It uses the second wave data of the China Health and Retirement Longitudinal Survey, which collected ageing and health-related information on a nationally representative sample of 8,906 older people aged 60 and over in 2013. Apart from the factors that have been examined in the contexts of developed countries, the paper further investigates two factors specific to Chinese society: rural–urban residence and regular financial assistance from children. Based on binary and multinomial logit regression analyses, the research findings are threefold: the determinants of receiving informal care differ remarkably according to the sources of care; disability and living arrangements are the most important determinants; rural–urban residence plays a vital role in the Chinese context, but regular financial assistance from children makes little difference. It is estimated that 53 million older people are receiving informal care each year, a figure equivalent to the entire population of England. With continuous population ageing, Chinese society will face huge pressure to meet the demand for social care among older people in the future. The Chinese government needs to build a well-rounded welfare system that tackles this challenge from multiple dimensions. The formal care services should aim to complement informal care in the short run and reduce inequality in social care in the long run.

The long-term care system in China relies heavily on informal care provided by family members. This study makes projections on the demand for informal care among Chinese older people between 2015 and 2035 and quantifies the level of long-term care resources needed to meet their needs. The data come from longitudinal information in a nationally representative sample, China Health and Retirement Longitudinal Survey 2011 and 2013. The macrosimulation approach (PSSRU model) and the Markov approach are integrated into one Bayesian modelling framework. The Monte Carlo simulation technique is used to capture parameter uncertainty. We project that the demand for informal care will increase from 41.3 million people (95% CI: 39.9–42.7) in 2015 to 82.6 million people (95% CI: 78.3–86.9) in 2035. The long-term care system faces unbalanced pressure of demand for informal care from different groups of older people. The projected demand is sensitive to changes in older people’s disability trajectory and the availability of formal care provided by the government, but less sensitive to an increase in singleton households in the future. We discuss possible policy measures to alleviate the mounting pressure on the demand for informal care.
