I don't think there is a list anywhere, but some states out east, and particularly those with heavy military population, like Virginia, are areas with particular competitive areas. Other areas my not be competitive at all. If you live in North Dakota , Montana, or states which are not heavily populated, there is a chance that your district may not have many applicants for Academy spots. If so, you may get in with just the minimal qualifications.
We live in mid Michigan, and I know my son was told during each of his moc interviews that 250 kids were being interviewed that day, which is, I suspect, average for the great lakes region. That included all academies.
It also is a matter of luck. If your MOC only has two applicants for one spot, but it happens that the other kid has a 36 ACT, is class President, all state football and baseball, second in his class standing, and saved three babies from a burning building, better luck next year.
Keep in mind, all these things are relative. Everything is compared against whoever the competition is. And usually there are very competitive candidates, so push hard on every single micro aspect of the application and process. Everything matters.
We thought my son was pretty solid with each Academy in terms of his resume. He was NHS president, five sport athlete in HS, including 4 years varsity soccer, three varsity baseball, All Dist and All Conf First Teams, top 15% class standing, and ACT scores of m34, e31, s34, and R30, but there were lots of very impressive candidates who he thought would get between him and an appointment. It worked out for him obviously, but I know other very qualified candidates missed out. My son was very motivated, and it kept him pushing hard with everything. He improved as a result. He ended with appointments to USMA and USAFA, but was only wait listed at USNA before dropping there.
Candidates should have a vision quest no matter what district they are in.
