“…Death counts were converted to rates using person-years at risk (PYAR) from the Human Mortality Database (2015). Five-year groups (40-44,45-49,...,95-99) were used to smooth heaping on preferential digits of age, as is common practice (f.e., Ho and Fenelon 2015). The exposure (i.e., PYAR) data from the Human Mortality Database are an appropriate match for the MCD data, since the MCD data, collapsed to all causes, is the same as the HMD mortality count data (the HMD does not, as of this writing, include cause-specific data).…”
