Through Life expectancy, Saving and Present value

For example, as of January 2026, the estimated underfunding of the United States Social Security program is $29.3 trillion or 1.5% of GDP over the years 2026-2100. This has been increased from $25.1 trillion in the previous year's report of the Social Security Administration. This amount would have to be set aside today so that the principal and interest would cover the program's shortfall between tax revenues and payouts over the next 75 years.

Background

The ratio of workers to pensioners, the "support ratio", is declining in most countries. This is due to two demographic factors: increased life expectancy coupled with a fixed retirement age, and a decrease in the fertility rate. Currentlty, over 50% countries are below the replacement rate of 2.1 child per woman. Increased life expectancy (with fixed retirement age) increases the number of retirees at any time, as individuals are retired for a longer fraction of their lives, while decreases in the fertility rate decrease the number of taxpayers to fund pension obligations.

In 1950 there were 7.2 people aged 20–64 for every person of 65 or over in the OECD countries. By 1980, the support ratio dropped to 5.1 and by 2010 it was 4.1. It is projected to reach just 2.1 by 2050. The average ratio for the EU was 3.5 in 2010 and is projected to reach 1.8 by 2050. Examples of support ratios for selected countries and regions in 1970, 2010, and projected for 2050 using the medium variant:

Key terms

  • Participation rate: The proportion of the population that is in the labor force
  • Defined benefit: A pension linked to the employee's salary, where the risk falls on the employer to pay a contractual amount
