REGIDOR, E. et al. Increase in differences in survival according to income per capita in Spain in the last quarter of the twentieth century. Gac Sanit [online]. 2003, vol.17, n.5, pp.404-408. ISSN 0213-9111. http://dx.doi.org/10.1590/S0213-91112003000500009.
Objective: To estimate probability of survival in Spain from 1975 to 1995 according to income per capita quintiles. Methods: The 50 provinces in Spain were ordered by income per capita in 1975, 1981, 1985, 1990 and 1995. For each quintile and year we estimated the probability of surviving 75 years from birth and the probability of survival in several age intervals in men and women. Probability was estimated by percentages. Subsequently, we calculated differences in the probability of survival between the highest and the lowest income per capita quintiles. Results: Differences in the probability of surviving from birth to the age of 75 years increased from 1.3 in 1975 to 3.1 in 1995 in women, whereas in men the increase was from 0.1 in 1975 to 3.7 in 1995. Conclusions: In Spain, as in other developed countries, socioeconomic differences in premature mortality increased in the latter decades of the twentieth century.
