Special Collection 2: Determinants of Diverging Trends in Mortality is a set of papers stemming from the first seminar of the Committee on Emerging Health Threats (CEHT) of the International Union for the Scientific Study of Population (IUSSP), "Determinants of Diverging Trends of Mortality"....

Compression of mortality is measured here in four ways: (1) by standard deviation of the age at death above the mode; (2) by standard deviation of the age at death in the highest quartile; (3) by the inter-quartile range; and (4) by the shortest age interval in which a given proportion of deaths...
