There are many reasons that could increase or decrease vital capacity in a person. Respiratory conditions are a major factor in how much air a person can take in.
The question is simply too broad, since "A tight sweater" and "OCPD" are equally valid answers to the question as asked.
Vital capacity can be decreased because of smoking. Smoking can cause emphysema which is a disease that makes it very hard to breathe.
Four factors that can affect the vital capacity of a person are age (vital capacity decreases with age), gender (males tend to have higher vital capacity than females), height (taller individuals usually have higher vital capacity), and physical fitness level (regular exercise can increase vital capacity).
It represents your maximum lung capacity minus the dead air space and the residual volume. It is the amount of air you can move after taking in the biggest breath you can and then blowing out all the air you can exhale. Some diseases reduce the vital capacity of the lungs and make it difficult to breathe.

My vital capacity is 1650cc (Yes, it's very low, but I'm twelve and I'm small). cc is used to measure vital capacity.
bigger body surface area = bigger vital capacity
A teenage girl will likely have the same vital capacity as an adult woman. About 5 to 6 liters of air would be the vital capacity for a 15 year old female.
Vital capacity is the amount of air you can breathe out after a maximum inhale. When it comes to determining vital capacity it’s basically calculated by the inspiratory reserve volume in addition to the expiratory reserve volume.
Vital Capacity (VC)
force vital capacity is measure when the patient is ecxhating with maximal speed and effort
higher vital capacity should help them to go to high pitch
