This economic burden is mostly growing in Asia and Europe; most of the countries in Europe like the UK, Germany and France provide nursing homes, while other countries like Japan provide life-long health insurance. The negative effect of the nursing homes in most countries is the stains on the National Health System (NHS) and government money as more funds are needed to provide medical care to the elderly.

If the retirement age remains fixed, and the life expectancy increases, there will be relatively more people claiming pension benefits and less people working and paying income taxes. The fear is that it will require high tax rates on the current, shrinking workforce. As fertility levels decline, the dependency ratio falls initially because the proportion of children decreases while the proportion of the population of working age increases.
