Editing Infant mortality (section)

==Classification==
Infant mortality rate (IMR) is the number of deaths per 1,000 live births of children under one year of age. The rate for a given region is the number of children dying under one year of age, divided by the number of live births during the year, multiplied by 1,000.<ref name="Andrews">{{Cite book |title=Encyclopedia of Infant and Early Childhood Development |vauthors=Andrews KM, Brouillette DB, Brouillette RT |publisher=Elsevier |year=2008 |isbn=9780123708779 |pages=343–359 |chapter=Mortality, Infant |doi=10.1016/B978-012370877-9.00084-0}}</ref>

Forms of infant mortality:
* [[Perinatal mortality]] is late fetal death (22 weeks gestation to birth) or death of a newborn up to one week postpartum.<ref name="Andrews" />
* [[Neonatal mortality#Neonatal mortality|Neonatal mortality]] is death occurring within 28 days postpartum. Neonatal death is often attributed to inadequate access to basic medical care, during pregnancy and after delivery. This accounts for 40–60% of infant mortality in developing countries.<ref name="Norton">{{Cite journal |vauthors=Norton M |date=April 2005 |title=New evidence on birth spacing: promising findings for improving newborn, infant, child, and maternal health |url=https://zenodo.org/record/1259057 |journal=International Journal of Gynaecology and Obstetrics |volume=89 |issue=Suppl 1 |pages=S1-6 |doi=10.1016/j.ijgo.2004.12.012 |pmid=15820364 |s2cid=26219456 |doi-access=free}}</ref>
* [[Postneonatal mortality]] is the death of children aged 29 days to one year. The major contributors to postneonatal death are malnutrition, infectious disease, pregnancy complications, [[SIDS|sudden infant death syndrome]], and problems in the home environment.<ref name="CDC-2022" />
