The United States population has increased significantly since the early 20th century and is projected to continue increasing in future years. As of October 2024, the U.S. has a population of more than 337 million residents, with a net increase of one person every 18 seconds.
As the U.S. increases in population, the country is also becoming more diverse. Currently, just over 75% of the population identifies as white. By 2060, the population of white Americans is projected to shrink to 68%, while all other racial and ethnic groups are expected to grow.
The most populated region of the U.S. is the South, with nearly 40% of all Americans. Approximately 20% of adults who live in the South report having fair or poor health. Obesity, diabetes and cancer are major health issues in the South and for the U.S. as a whole. Approximately 60% of adults in the U.S. have at least one chronic health condition, while 40% have two or more conditions. Opioid addiction and infectious diseases are other health challenges facing Americans.

Current Reports
America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.
We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
