Marriage rates are declining, especially in the richest countries

Marriage is experiencing a general decline

Marriage has taken drastically different forms than in the past. The transformation of marriage from a form of economic dependency for women to an equal partnership has forged demographic shifts. Richard Reeves, author of "Of Boys and Men," explains how economic and educational factors have potentially destabilized partnerships and changed patterns of “marriageability” for middle- and lower-class men.

Divorces in the US have been steadily declining over the past few decades

Despite these recent declines, divorce rates in the US remain between 40% and 50%. But there’s some nuance to those numbers. For instance, having a college degree makes individuals 30% less likely to divorce than those without one. People who attend church are also less likely to divorce. And prenuptial agreements are considerably likely to prevent contentious court battles.

South Korea has the lowest fertility rate in the world

If current birthing trends persist, every hundred South Koreans today will have only six great-grandchildren between them.

Marriages are more at risk when the woman is sick

A study tracking 25,000 copies over 18 years revealed marriages tend to end in divorce more often when the woman is sick. Conversely, men's health issues do not impact divorce rates.

Should married couples combine finances?

Millennials who live together are more likely to keep their finances separate than any previous generation.

Various pollutants may be contributing to a male infertility crisis

Male infertility, due to declining sperm counts or quality, accounts for about half of the cases of infertility among couples.

From 2000, this rate of decline accelerated to more than 2.6% per year. (Some users may encounter a paywall.)

Individuals typically spend less time with others as they get older

South Asia and sub-Saharan Africa are most at risk from falling pollinator numbers

Researchers at the Harvard T.H. Chan School of Public Health found that declines in pollinator populations would lead to higher rates of nutritional deficiencies, particularly in developing nations. Nations with large populations, such as China and India, would also be significantly impacted.

25% of US households had no regular income as of 2024

Some states had higher shares of no-income households than others: West Virginia, for instance, had a national high of 34% of households with no income. These states tend to have older populations, higher rates of disability, and lower median incomes overall. In such contexts, a larger portion of households rely on non-earned income sources or report no income during the survey period.

Falling demand and lower costs of production cause deflation

"Falling demand" refers to anything that changes someone's willingness to spend money on goods and services. Global recessions, fears of a worldwide recession, and a fall in the money supply are all factors that could lead to falling demand. Likewise, lower production costs allow companies to increase production, which can lead to a surplus in supply.
