A more meaningful question would be to ask how much a person "wants to AVOID dying and continue LIVING". In many cases, a person won't fear dying as long as there isn't pain or misery involved that is most common.
An old mentally and physically diminished person, even not in pain, may welcome death while a fit, healthy, financially solid person, like I am, may have tremendous reasons for not wanting to die, possibly losing existence forever eternally. Thus a reason death is arguably the saddest reality for we mortals that love and enjoy life. I wish to exist eternally and could do so happily content here on Earth.
By asking "Are You Afraid to Die?", that tends to point to religious afterlife factors, being afraid of the unknowns, especially if wondering if afterlife is a possibility or not. Although I have unique Christian beliefs, I have little confidence in the way eternal life is framed with church dogmas beyond what Jesus actually related in the New Testament, that is very limited. Thus one needs to have HOPE and FAITH.
Those who lean towards narratives it will be life in a paradise of Heaven are doing so on considerable imaginative dogma not supported by scripture. For instance even if one receives some kind of eternal life after mortal existence, the form one exists in and what they may do, may be unequal depending on the evaluation of one's life when alive. And it may be as I tend to expect, that most humans just die ending existence and become dust without the Hell narrative much like a stepped on ant.
