Our study is US-centric and originated from discussions of the SOA's MP-2014 table. There was some
controversy that the scale excluded more recent trends, specically a slowing of mortality improvement

tables to the MP-2015 tables to include two additional years of mortality experience, and the new tables
did in fact re
ect a material drop in mortality improvement. In the interim, the CDC has also released
new data showing a continued decline in mortality improvement levels
