There are, very often, considerable discrepancies when countries are ranked according to the values of each of the common health indicators. By the use of computed linear discriminant functions the authors developed a single indicator designed to convey the information gathered from the following health indicators: life expectancy at birth (LE), birth rate (BR), infant mortality rate (IMR), quantified indicator of Guedes (GI), general mortality rate (GMR) and mortality rate (MR) by infective and parasitic diseases (MRIPD), the last two age adjusted. For the construction of this adjustment a median standard population was suggested and used, each age group contributed with the average of the percentages of participation of the group in the composition of the population of each one of the 44 countries studied. These were those for which it was possible to get reliable data for the years around 1980. The contrasted groups in computing discriminant functions, each one consisting of 12 countries, were defined according to a criterion based on the rank of the sum of the normal reduced deviations calculated for the distributions of the values for each indicator. For the computation of discriminant function equations by the stepwise technique, reciprocal transformation was used for the four indicators expressed as ratios and for the other two their face values were used. Critical analysis of results as shown that the formula: Z = 2895/IMR + 2060/BR + 1000/MRIPD, can be used as a comprehensve indicator allowing the ranking of countries in broad classes of health levels, as follows: A - 737 or more; Denmark and Sweden; B - 637 |- 737: Australia, Netherland, England and Wales, Iceland, Luxembourg, Norway and Switzerland; C - 537 |- 637: Federal Republic of Germany, Canada, Scotland, Finland and Japan; D - 437 |- 537: Austria, Belgium, United States, France, Northern Ireland, Italy and New Zealand; E - 337 |- 437: Bulgaria, Spain, Greece, Hong Kong, Hungary, Ireland, Israel and Singapore; F - 237 |- 337: Barbados, Costa Rica, Yugoslavia, Poland, Portugal and Romania; G - 137 |- 237: Chile, Guyana, Mauritius, Panama, Trinidad and Tobago and Uruguay; H - < 137: Egygt, Guatemala and Mexico.
