In human reproduction, a live birth occurs when a fetus, whatever its gestational age, exits the maternal body and subsequently shows any sign of life, such as voluntary movement, heartbeat, or pulsation of the umbilical cord, for however brief a time and regardless of whether the umbilical cord or placenta are intact.
This definition of the term "live birth" was created by the World Health Organization in 1950 and is chiefly used for public health and statistical purposes. Whether the birth is vaginal or by Caesarean section, and whether the neonate is ultimately viable, is not relevant to this statistical definition. However, the term "live birth" was in common use long before 1950.
In the United States, the term "born alive" is defined by federal statute.

—G.C. (Georg Christoph)
“I wouldn’t put it past God to arrange a virgin birth if He wanted, but I very much doubt if He would.”
—David Jenkins (b. 1925)
