Does Fitbit take into consideration your age for generating your data?

Does fitbit take into account your age?  Seems like it is the same for 20 year olds and 80 year olds.

Hi @normondo and warm welcome to the Community ! 
I appreciate your message. 
Your Fitbit device combine your basal metabolic rate (BMR)—the rate at which you burn calories at rest to maintain vital body functions (including breathing, blood circulation, and heartbeat)—and your activity data to estimate your calories burned. If your device tracks heart rate, your heart-rate data is also included, especially to estimate calories burned during exercise. The number you see on your Fitbit device is your total calories burned for the day.

Your BMR is based on the physical data you entered in to your Fitbit account (height, weight, sex, and age) and accounts for at least half the calories you burn in a day. Because your body burns calories even if you’re asleep or not moving, you see calories burned on your device when you wake up and will notice this number increase throughout the day.

Fitbit does take your age into account for several calculations.  The ones I can think of right now are heart rate zones, fitness levels, typical ranges for different sleep stages.  There are probably more that don't come to mind right now.
