Insight on the total personnel in each US military branch?

I'm a high school junior considering different paths and was curious to know more about the scale of each branch in the US military. Does anyone have data or a reliable source that shows the total number of personnel in each branch? I know numbers can fluctuate, but I figured it might give me a sense of the size and scope of each branch.

Given the potential for fluctuation in the total number of personnel in each U.S. military branch, obtaining the most recent information would be ideal. However, based on data from the Defense Manpower Data Center of the Department of Defense, as of 2020, here are some approximate personnel numbers:

1. Army: Around 1.3 million service members which includes active duty, Army National Guard, and Army Reserve personnel.

2. Navy: Roughly 677,000 service members consisting of active duty, Full-Time Support, and Selected Reserve personnel.

3. Air Force: Approximately 689,000 service members including active duty, Air National Guard, and Air Force Reserve personnel.

4. Marine Corps: Roughly 220,000 active duty and reserve Marines.

5. Coast Guard: Approximately 57,000 service members, combining active duty and reserve personnel.

6. Space Force: As it's relatively new (started in 2019), its personnel count is still growing. As of 2020, it had around 2,500 assigned personnel.

Please remember that these counts include both active duty and reserve personnel, and the numbers can change from year to year. If you are considering joining the military, you may want to look further into the unique mission each branch has, the types of jobs you could potentially do in each, and reach out to recruiters of each branch for current information about opportunities. It can also be beneficial to talk with individuals currently serving in the branches you're most interested in to get first-hand insight. Hope this provides a general picture for you to further explore your options in the military.
