This paper describes and explains the recent trends in life expectancy at
birth in Spain from an interdisciplinary perspective. It is based on two
methods: segmented linear regression, and decomposition of life
expectancy. The study consists of three sections. First, a description is
provided of the demographic factors that explain the increase in the life
expectancy at birth of the Spanish population from 1910 to 2009, which
is in excess of 40 years. Second, the effect that changes in mortality
have had on life expectancy at birth during 1980-2009 is analysed by
cause of death of the population aged 65 and above. And third, the
social and epidemiological causes underlying that increase are
described. It is concluded that the increase of life expectancy at birth in
Spain is mainly due to the reduction of mortality at advanced ages and
a decrease in cardiovascular mortality.
