A recent trend is developing globally that links marriage and having children with financial stability. The decision to marry and raise a family is increasingly tied to financial security, a trend that is also prevalent in Japan. The trend displays itself in various forms, including delayed marriages and declining birthrates, chiefly among those who experience financial instability or insecurity.

In Japan, the high cost of living, particularly in urban areas, has impacted people's decisions about marriage and childbirth. Japanese society highly values family, marriage, and children, and this trend reflects the challenges faced by many young adults in balancing cultural values with economic realities. This societal change is causing worry among policymakers due to its effects on Japan's aging population and the sustainability of the workforce.

Similar to Japan, individuals in the US and EU are also making decisions about marriage and family based on their economic circumstances. However, the extent of the trend varies. In the EU, substantial social welfare programs can potentially mitigate the impacts. Meanwhile, in the US, where welfare support is less comprehensive, economic factors might have a more significant impact on decisions about marriage and family.
