|November 2019||Water Purification Efforts and the Black-White Infant Mortality Gap, 1906-1938|
with , , : w26489
According to Troesken (2004), efforts to purify municipal water supplies at the turn of the 20th century dramatically improved the relative health of blacks. There is, however, little empirical evidence to support the Troesken hypothesis. Using city-level data published by the U.S. Bureau of the Census for the period 1906-1938, we explore the relationship between water purification efforts and the black-white infant mortality gap. Our results suggest that, while water filtration was effective across the board, adding chlorine to the water supply reduced mortality only among black infants. Specifically, chlorination is associated with an 11 percent reduction in black infant mortality and a 13 percent reduction in the black-white infant mortality gap. We also find that chlorination led ...
|March 2019||The Phenomenon of Summer Diarrhea and its Waning, 1910-1930|
with , : w25689
During the first two decades of the 20th century, diarrheal deaths among American infants and children surged every summer. Although we still do not know what pathogen (or pathogens) caused this phenomenon, the consensus view is that it was eventually controlled through public health efforts at the municipal level. Using data from 26 major American cities for the period 1910-1930, we document the phenomenon of summer diarrhea and explore its dissipation. We find that water filtration is associated with a 15-17 percent reduction in diarrheal mortality among children under the age of two during the non-summer months, but does not seem to have had an effect on diarrheal mortality during the summer. In general, we find little evidence to suggest that public health interventions undertaken at t...
