Calcium is stored in the bone marrow until the body needs it, at which point it is removed and taken to the place in the body where it is required, such as at a blood clot. The amount of Calcium in one's bones is called their bone density, and when, women especially, grow middle-aged and become elderly, the Calcium is often lost from their bones, and this makes their bones porous and fragile. If they did not eat enough Calcium when they were younger, then this is far more likely and will happen far more quickly.
So, yes, osteoporosis is a deficiency disease of Calcium, but its effects tend to be delayed.
A lack of calcium causes the condition of osteoporosis (Latin for 'Holes in the Bones) making them brittle and easily fractured. Milk, cheese, and fortifies milk are good sources of calcium and vitamin supplements are not required for a diet rich in calcium. I recommend a child/teenager to drink at least a glass of milk a day, adults 1/1 and a half.

Calcium is essential for strong bones and teeth. Calcium deficiency can lead to disorders like osteoporosis (brittle bones)
Estrogen deficiency can increase a woman's risk of developing osteoporosis and ischemic heart disease.
It is called a nutrient deficiency, or starvation.
