The results of the multiple regression and correlation analysis between perinatal mortality and social and health care variables in Spanish provinces between 1975 and 1979 are presented. Although the perinatal mortality rates of Spanish provinces correlate significantly with a series of socioeconomic variables (family income available per capita, percentage of active population in primary sector, educational level of women at childbearing age) and health care variables (active obstetricians per 1000 live births and active pediatricians per 1000 live births), the multiple correlation and regression analysis has shown that the most important variable is the family income available per capita: 44% of the variability of perinatal mortality in Spanish provinces can be accounted for by this factor. By regression analysis, it is also possible to predict a decrease of 0.065 points in perinatal mortality for every additional 1000 pesetas in the family income available per capita.
