Which term describes the number of children who do not survive to the age of 1 per 1,000 live births?

The term that describes the number of children who do not survive to the age of 1 per 1,000 live births is "infant mortality." This statistic is a critical indicator of the overall health of a population and reflects factors such as maternal health, nutrition, access to clean water and sanitation, and healthcare quality. A high infant mortality rate suggests that there may be significant health issues within a community or country, while a lower rate typically indicates better healthcare systems and living conditions for mothers and infants.

Life expectancy refers to the average number of years a person is expected to live, which is not specific to infants. Rural-urban migration pertains to the movement of people from rural areas to urban centers, related to demographic studies rather than health metrics. Amenities refer to the desirable or useful features of an area or housing, which do not directly measure child survival rates. Thus, infant mortality is the most accurate term to describe the issue of child mortality before the age of one.
