The population of the United States is approximately 332 million as of 2023. This figure includes all individuals residing within the country's borders, regardless of citizenship status. The demographic makeup of the U.S. is diverse, with a significant portion of the population identifying as Hispanic, Asian, Black or African American, White, or belonging to other racial or ethnic groups. The distribution of this population is uneven, with certain regions, such as California and Texas, hosting larger populations compared to others.

The growth rate of the U.S. population has been gradually declining over recent decades. Factors contributing to this trend include lower birth rates and increased life expectancy. Despite this slowdown, the population continues to grow due to immigration and natural increase.

Urban areas often have higher population densities than rural regions. Major cities like New York City and Los Angeles are home to millions of people and serve as economic hubs for their respective states and beyond. However, rural areas also play a crucial role in the country's agricultural sector and provide essential services for their residents.

Understanding the population dynamics is vital for policymakers when addressing issues such as healthcare access, education, housing, and economic development. Accurate data on population size and composition helps in formulating effective strategies to meet the needs of all citizens.
