The world’s population is ageing: almost every state in the world is undergoing growth in the number and proportion of older persons in their population. The gradual change from a younger to an older population age structure is summarized by the term “population ageing”, which is increasingly becoming one of the most important social transformations in the contemporary society.
The increase in the median age may have implications for sustainable development policies in nearly all sectors of society and, as populations become increasingly aged, it is important that governments understanding their implications for present and future policies to achieve sustainable development through the design of innovative policies and public services specifically targeted to older persons, anticipating current and future demographic trends.
The California Department of Finance has recently issued population projections for the state’s counties to 2060 in which the state assumed to reach a population of 45 million by 2035, and 50 million during 2055. Between 2016 and 2060, the state is expected to grow by 30 percent: from 39.4 million to 51.1 million, adding over 11.7 million people. Within this population growth, in 2060 more than 30% of the population in California will be over 65 years old, with an increase of nearly 20% from the current 11%.
