The Effect of Water Filtration on Cholera Mortality Daniel Knutsson

There is debate among researchers regarding the importance of water filtration in reducing mortality during the epidemiological transition. However, there is limited research on how water filtration affected cholera mortality during the second half of the 19th century.

Using historical microdata, this paper provides new evidence on the importance of water filtration in reducing cholera mortality during an outbreak. The results show that access to filtered water protected almost completely against cholera mortality. Water filtration could thereby have contributed more to mortality decline than what has previously been documented.

Interdisciplinary European Studies

The European Union and the Return of the Nation State


This book explores the complex and ever-changing relationship between the European Union and its member states. The recent surge in tension in this relationship has been prompted by the actions of some member state governments as they question fundamental EU values and principles and refuse to implement common decisions seemingly on the basis of narrowly defined national interests.

Seminars organized by IFN


To present ongoing research informal brown-bag seminars are held on Mondays at 11:30 am. This is an opportunity for IFN researchers to test ideas and results.

Academically oriented seminars are most of the time held on Wednesdays at 10 am. At these events researchers from IFN and other institutions present their research.

In addition, IFN organizes seminars open to the public. Topics for these are derived from the IFN research.
