Life expectancy in 1800, 1950, and 2015 – visualization by Our World in Data. Public health measures are credited with much of the recent increase in life ...
Between 2010 and 2014, babies in the United States had an approximately 70% survival rate when born under weight of 500 g (1.10lb), an increase from a 30.8% survival rate between 2006 and 2010. [15] A baby's chances for survival increases 3 to 4 percentage points per day between 23 and 24 weeks of gestation, and about 2 to 3 percentage points ...

Premature birth is associated with a 1.2x to 1.6x increase in all-cause mortality rates during early to mid-adulthood. Those born extremely prematurely (22–27 weeks) have an even higher mortality rate of 1.9x to 4.0x. [3]
