Insufficient birth spacing in families

Name(s): 
Reduced intervals between pregnancies
Incidence 
A survey of 6,000 women in India has shown infant mortality rates of approximately 80 per 1,000 where the interval between births was three to four years, rising to 200 per 1,000 when the interval between births was less than one year. A greater than 100% reduction in infant morality under age one is achieved in the following countries when births are spaced at least two years apart: Northeastern Brazil, Pakistan, Nigeria, Egypt, Indonesia, Turkey. In the USA, it has been estimated that infant mortality rates could be reduced by almost a third if no woman were to have more than three well-spaced births.
Claim 
Medical workers, when caring for a mother and her young child, have come to realize that delaying the next conception and extending the interval between births are quite as important a part of health care as seeing that the latest child is adequately immunized.
