According to the U.S. Census Bureau, the estimated population of the United States is approximately **336 million** as of mid-2024.

It's important to know that this number is constantly changing. The Census Bureau provides a "Population Clock" that shows these changes in real-time, based on the following projections:

*   One birth every **9 seconds**
*   One death every **10 seconds**
*   One international migrant (net) every **28 seconds**

This leads to a net gain of one person approximately every **21 seconds**.

### For Reference:

*   **Official 2020 Census:** The last official count, completed on April 1, 2020, was **331,449,281**.
