It's basal metabolic rate; the number of calories it takes to keep you alive and out of a coma. You can take your stats, weight, height, gender and put them in a bmr calculator to get yours. there are plenty of them accessible via google.
Your BMR (basal metabolic rate) is the amount your body uses each day just to keep you alive... your heart needs to pump blood, you need to breathe, you still need to keep warm (or cool down), all of these processes plus the multitude of others are using energy whether you're awake and moving or stationary in a coma.
Your BURN is the amount of energy you're using per day for everything combined, so your BMR plus any activities through the day from showering to working to exercising to laughing at that funny picture in your mailbox. The more you move & the more muscle you have, the more you'll burn.
The DEFICIT you have should come from the burn amount, not the BMR. It is generally advised that you eat at least your BMR and let your deficit come from your additional activities. For example, if someone burns 2200 per day and they're looking to lose 1lb per week, they could have a deficit of 500 per day, still leaving them 1700 to eat per day. These numbers are just a general, standard example, use the burn meter tool to get an idea of what your actual burn is per day.
1952 sounds about right for your stats. As a teen you'll naturally have a high BMR because you're still growing - that is the minimum amount you should be eating per day at the moment to keep your vitals functioning properly (heart, breathing, temperature regulation). Because you're still growing, you require more calories than an adult of the same stats - you may not be getting taller but bones, muscles, brain and internal organs are still developing.
A calculator to see your burn amount per day can be found here, it is a calculator specifically designed for those aged 2-20 years. The ones on CC are for when you're 21 or over :)
