The 50 US States Ranked by Popuplation Today - The Largest and Smallest

Unlike China and India, the United States population is expected to continue to grow throughout the century with no foreseeable decline. By 2067, the U.S. population is expected to surpass 400 million people.

The population growth in the United States is mainly attributed to high rates of immigration, which have decreased since 2016, and the natural increase (the difference between births and deaths).

The United States population grows on average about 0.9% every year. The population grew 0.60% in 2019; the lowest rate the U.S. has had in a century. This is because of a decrease in the number of total births over the year. Additionally, more post-World War II baby boomers are reaching old age, increasing the number of deaths.

Despite a decrease in the population growth rate in recent years, the population is still expected to grow continuously. Here are the 50 States in the United States ranked by population.
