How the U.S. Population Size Could Change

U.S. Population Expected to Reach 335.9 Million in 2024

As the United States bids farewell to 2023, the U.S. Census Bureau has revealed that the country’s population has grown by over 1.75 million people over the past year. With the arrival of the new year, the population is projected to reach 335,893,238. This increase represents a growth rate of 0.53% since January 2023 and a significant rise of 4,443,957 individuals since the April 1 Census Day in 2020. The Southern and Western regions have experienced the most substantial population growth, while the Midwest and Northeast have seen more modest increases.

Births, Deaths, and Migration: Factors Shaping Population Change

In the coming month, the Census Bureau estimates that the U.S. will witness one birth every 9 seconds and one death every 9.5 seconds. Additionally, international migration is expected to contribute to the population by one person every 28.3 seconds. When these factors are combined, the U.S. population is projected to grow by one person every 24.2 seconds.

Long-Term Projections: A Peek into the Future

Looking ahead, the Census Bureau has made long-term projections for the U.S. population. By 2080, it is anticipated to reach a peak of nearly 370 million people. However, after this point, the population is projected to gradually decline, reaching approximately 366 million by 2100. These projections are subject to various factors such as birth rates, mortality rates, and immigration patterns.

The U.S. Population on the Global Stage

In terms of global population rankings, the United States currently holds the third position, trailing behind China and India. According to the Census Bureau’s Population Clock, the U.S. is expected to maintain this ranking in the foreseeable future. Indonesia and Pakistan complete the top five countries with the largest populations.

A Global Perspective: Population Growth Worldwide

While the United States experiences its own population changes, the global population continues to climb. Just over a year ago, the world reached a milestone of 8 billion people, having surpassed 7 billion in 2011, as reported by the United Nations. As the clock strikes midnight on New Year’s Day, the global population is estimated to be 8,019,876,189, according to the Census Bureau’s calculations.

Officials predict that in January alone, there will be 4.3 births and 2 deaths every second worldwide. Looking ahead, the world’s population is projected to exceed 10 billion over the next 60 years, indicating significant growth on a global scale.


As the United States enters the new year, the Census Bureau’s data offers insights into the expected changes in the country’s population size. With a projected population of 335.9 million in 2024, the U.S. continues to experience growth driven by factors such as births, deaths, and international migration. While the U.S. population is set to reach a peak of nearly 370 million by 2080, long-term projections suggest a gradual decline thereafter. These trends highlight the dynamic nature of population changes and their implications for the United States and the world as a whole.
