The U.S. population growth is projected to slow significantly, with a peak in 2048, and a decline to zero by 2055. This is due to historically low fertility rates and an aging population. The country's population growth has been declining since 2005, with a 0.2% growth rate in 2025. By 2048, net immigration and natural population decline will cancel each other out, resulting in a peak population. In contrast, Singapore leads the world in math performance, with an average math score of 575. Asian economies dominate the global top five, with Macau, Taiwan, Hong Kong, Japan, and South Korea following closely behind. The United States ranks 33rd out of 35 countries, below the OECD average. Social trust is highest in Northern Europe, led by Sweden and the Netherlands. Middle-income countries tend to report much lower trust in others. This is reflected in the U.S. population growth projections, which show a decline in births and an increase in deaths, with net immigration becoming a more important driver of population growth.
