The population growth in Lao PDR, along with its changing structure and regional distribution, will have decisive impacts on health services to 2030. As the population grows, the demand for medical services and for hospital beds increases. With the overall projected population increase, proportions in the total population vary. Changes in age composition are leading to a larger elderly population and growth in the share of females of reproductive ages from 15–49 years, with consequent change in demand for health services for each group population group. During this same timeframe, based on the the total fertility rate the population of the youngest ages (0–9 years) are projected to decrease.
