Aging Population Not Exactly a Bad Scenario for Society

While population aging, i.e the rising average age of the population, is seen as a problem by many academics, a new study published in PLOS ONE suggests that it could have a positive impact on the society.

"In order to give a more complete picture of population aging, it is necessary to include both positive and negative effects of population aging," says IIASA researcher Elke Loichinger, who wrote the article in collaboration with researchers from the Max Planck Institute in Rostock, Germany, and the University of Washington.

The researchers chose to use Germany as a case study because the country is at an advanced stage of the demographic transition, with a current fertility rate of around 1.4 and the second oldest average population in the world (median age 44.3 years). They identified five areas in which population aging could bring net benefits, when considered in combination with other demographic factors:

Increased productivity: While population aging will likely lead to a decline in the labor force, expected increases in workers' education levels can partly compensate for this decline through higher productivity.

Aging could be good for the environment: Changes in the age structure and a declining population size are associated with reduced consumption of energy-intensive goods and lower carbon dioxide emissions.

Sharing wealth with the younger generations: As life expectancy increases, people would inherit, on average, at older ages and potentially use some of the inheritance to either fund their retirement or help their children financially as they become adults. Moreover, as families have fewer children, inheritance will be split between fewer people, so that, all else being constant, individuals would receive more on average.

Health: As people live longer, they also stay healthier longer. The results project that the average German man in 2050 will spend 80% of his lifetime in good health, compared to 63% today.

Quality of life: The study suggests that the relationship between leisure, work, and housework will change in the future, with leisure time increasing on average.

While the study focused on Germany, the researchers say that the findings are applicable across many aging societies. Loichinger says, "The particular context of another country will determine the degree of their relevance. For example, an increase in educational attainment levels can be found almost universally around the globe, and the finding that the elderly belonging to subsequent cohorts have better health has also been shown in other contexts. Depending on a country's stage in the demographic transition process, the results from the analyses of bequests and CO2 emissions are also generalizable." The study provides a new perspective at a time when population aging is spreading to many countries around the world. Loichinger says, "The extent of population aging that is going on and expected is beyond what has ever been observed before. Since there is no precedent to this development, there is also no blueprint how to deal with it."
