birth

 [berth]
a coming into being; the act or process of being born.
birth certificate a written, authenticated record of the birth of a child, required by state laws throughout the United States. After a birth is registered, a birth certificate is issued which represents legal proof of parentage, age, and citizenship, and is of great personal and legal importance. A birth certificate is required for many legal and business or personal transactions. Whether the child is born at home or at the hospital, the physician, midwife, or other attendant must report the birth to the local or state registrar. The report becomes a permanent record, and a certificate is issued to the parents. If a child dies during birth, an immediate report and certification of the birth and death are required, containing a statement of the cause of death.
birth control the concept of limiting the size of families by measures designed to prevent conception. The movement of that name began in modern times as a humanitarian reform to conserve the health of mothers and the welfare of children, especially among the poor. More recently it has been superseded by the term family planning, which means planning the arrival of children to correspond with the desire and resources of the married couple. See also contraception.
multiple birth the birth of two or more offspring produced in the same gestation period.
premature birth (preterm birth) expulsion of the fetus from the uterus before termination of the normal gestation period, but after independent existence has become possible; defined as birth occurring before 37 completed weeks (295 days), counting from the first day of the last normal menstrual period. Approximately 6 to 8 per cent of all live births in the United States are premature, and premature births are the major cause of neonatal morbidity and mortality.
