Aging (and shrinking) populations

It’s most relevant to pensions/Social Security systems, so I’ll drop it here

Okay, this visualization is not so much about aging.

Here’s the text that matches the title:

In 2020, more than 147 million people around the world were between the ages of 80-99, accounting for 1.9% of the global population.
While that percentage may seem small, that particular demographic accounted for merely 0.05% of the population in 1950, meaning our world has a notably higher percentage of older people than it did 70 years ago.

Why is this significant? An aging population typically means a declining workforce and an increase of people looking to cash in their pensions. This can put pressure on the working class if taxes are raised.

Of course, an aging population can have positive impacts on society as well. For instance, elderly citizens tend to volunteer more than other age groups. And research has shown that older communities have lower crime rates. By 2050, the crime rate in Australia expected to drop by 16% as the country’s population gets older.

To mitigate some of the risks associated with a rapidly aging population, certain countries are working towards more sustainable pension systems, to support aging citizens while taking the stress off the working population.

Japan’s population figures have been on a troubling trajectory in recent years. A rapidly greying society, combined with low birthrates and virtually non-existent immigration, has put Japan on the path of significant population contraction. In 2018 the population declined by 449,000, the largest such drop since record-keeping began in 1968. Census figures show a population contraction of nearly 1 million people since 2010.

Compounding the issue is what Meiji University professor Hisakazu Kato calls the “pole society” phenomenon, wherein the poorer, rural prefectures with higher birth rates lose residents to the economically strong, but low-birth rate, metropolises such as Tokyo and Osaka. That one-two punch has contributed to the country’s chronically low birthrate, putting the country on the path of a projected loss of one-third of its population by 2065.

As a town’s older residents move to assisted living facilities or die, their homes pass down to their heirs. Younger generations, now increasingly located in Japan’s major cities, often have no interest in inheriting or maintaining the family’s ancestral home deep in the countryside, beyond paying the required property taxes. In other cases, officials are unable to locate or identify the proper heirs, leaving the fate of the property in a state of limbo.
