Sustainability of publicly-funded health care systems concerns governments worldwide as health care absorbs increasing shares of public funds and GDP. Planning future requirements for health care services, providers and funding is typically based on applying current supply by age to demographic population projections. Temporal changes in age-specific health undermine this ‘constant use by age’ assumption and drive expenditure increases. An approach to estimating future health care requirements is presented incorporating cohort trends in health. Although overall health care requirements increase as the size and mean age of the population increase, these effects are mitigated substantially by cohort trends in health.
