In demography, certain terms which have been taken from everyday language are used to denote different stages of life 1 or an approximate range of years. At the beginning of life comes childhood 2. In general a child 3 is a person who has not yet attained puberty (620-2). In the very early days of life, the child is called newborn 4. The term infant 6 may be used to denote a child who has not reached its first birthday, though in colloquial language it may be applied to slightly older children. Children who have not yet reached the compulsory school age are called pre-school children 7, a school-age child 8 is a child at an age at which it is customary to attend school.
