United States Population is Expected to Grow Over the Next Decade

The population of the USA is currently over 326 million people, and it will grow by about 10 percent over the next decade. This growth will increase to about 33 million people, and the population will be around 359 million by 2029.

The population growth is not evenly spread throughout the country, however. Some states will see more increases than others. California, Texas, and Florida will gain several congressional seats, while the Northeast and Midwest will lose seats.

There are a few reasons why the Census Bureau projects the population of the USA to grow over the next decade.

The current population is aging

According to the Census Bureau, one enormous factor in the projected population of the USA is a significant drop in fertility rates. In general, there has been a trend in the United States for women aged 35 to have fewer children than those under age 35. The number of births by women aged 45 and older more than tripled from 1980, and the number of births by women under age 25 declined by 30%.

More immigrants are entering the United States than leaving


In 2011, approximately 40 million immigrants were living in the United States. Of those immigrants, 13.1 million were naturalized citizens and 26.4 million were not U.S. citizens. One factor in the population boom is an influx of immigrants.

According to the Census Bureau, net immigration accounts for about one-fourth (23.9%) of overall population growth and has accounted for a majority (55%-61%) since 1965.

It is not just births and immigrants

There are a growing number of people who are choosing to live longer. The number of centenarians (people over 100 years old) in the United States increased from 53,364 in 2010 to 72,197 in 2016. As the population of the USA continues to grow and age, the number of people over age 65 is projected to more than double, from 46.2 million to 98.2 million over the next 30 years.

The United States Census Bureau uses these projected population numbers to determine the number of congress members for each state.

There are both pros and cons to this population growth.


More people means more consumers and potential employees

More people may lead to more innovation and creativity

A larger population may make the United States more powerful politically and economically


The United States may not be able to provide enough resources for all of its citizens, such as food, water, and housing

The United States will need to invest more money into infrastructure, which could lead to increased taxes

The United States may see crowded roads and schools if the population continues to grow at the current rate.

The bottom line

While the population of USA is expected to grow by nearly one-fourth (23.9%) over the next decade, the population of countries such as Japan, Germany, and Italy is projected to shrink.

The Census Bureau’s projections are relevant for many reasons. States rely on these population numbers to determine how many congressional seats they will have. In addition, the data helps the federal government determine how much funding each state will receive for entitlement programs.

The jump in population of USA is a piece of splendid news, not only because of the additional tax revenue that this brings but also because having more people within our borders means more people are working and paying taxes. It’s an exciting time to be alive!
