PIP: In 1991 in Denmark, there were 64,645 children born: 64,349 were born live while 296 were stillborn. In 1990, 63,731 children were born, 914 fewer than in 1991. In 1991 the number of births was 26.5% over the level of 1983, the annual rate increasing 3.4% since 1989. The number of live-born children increased by 3382 from 1991 to 1992 corresponding to rate of 5%. In 1991 the rate of perinatal mortality was 8.0/1000 born. The perinatal mortality of children weighing less than 1000 g was 7.5/1000 born in 1982, compared to 6.0/1000 in 1991. In 1989 the counties of Roskilde, Ribe, Viborg, and Nordjylland had a perinatal mortality over 10/1000; in 1990 only Ribe county had a rate over 10/1000; however, in 1991 the counties of Bornholm and Ribe had a rate over 10/1000. Until 1989 women in the 20-24 age group gave birth to more children than women in the 30-34 age group, but in 1991, 20.4% of children (13,208) were born to women aged 20-24 and 25.4% (16,409) to women aged 30-34. Most (42% or 27,160) were born to women aged 25-29. In 1991, 200 children were born with an extremely low birth weight (up to 999 g), the same number as in 1989. About half of these babies died during the perinatal period, and 15% died in the course of the first year of life. Consequently, infant mortality is significantly dependent on birth weight and it is the lowest for children with a birth weight between 3000 and 5000 g.
