How has military service changed geographically since 1973? Why?

Southern states have begun to contribute more and more since the time especially Texas.

Explanation:

It is seen in the trend that there are more southern people who have a culture of joining the army than any other and it is specially true for Texas.

One other state Colorado and a few other states that have actually begun to contribute more are on the west coast with the east coast contributing the least to the army and there being a lack of actual need to get in and get drafted.

This has come to be due to the increase in the Conservationism of the people in south and the disillusion of the urban with the army.
