As of 2023, there are approximately 19 million veterans living in the United States. This number is continually changing due to various factors such as aging and mortality rates among the veteran population.

The U.S. Department of Veterans Affairs (VA) provides updated statistics regarding veterans, including their demographics and the number of living veterans. Overall, the veteran population has been declining over the years, primarily due to the aging of veterans from World War II and other earlier conflicts.

For the most accurate and updated figures, it's always best to refer to the VA's official resources or recent reports on veteran demographics.
