The provision of sanitation is lowest in the Americas with 43% of health care facilities lacking adequate services.

It treats health as a stock that provides direct utility. Health depreciates with age and the aging process can be countered through health investments.
As of 2017, 22% of health care facilities in the least developed countries had no water service, with similar numbers lacking sanitation and waste management services. [18] The statistic in the 2017 baseline estimate by the JMP is that 4.5 billion people currently do not have safely managed sanitation. [14]
