Patternaof Mortality in Childhood rate was also high, larger proportions of mothers were young (24.2 per cent under 20 years and 30.0 per cent aged 20-24 years), while Monterrey had a lower percentage under 20 years (14.1) and a higher percentage 35 years and over (18.4). The pattern in Kingston-St. Andrew (with the fourth highest birth rate) was similar to that in El Salvador, with a predominance of young mothers but with an even lower percentage 35 years and over (11.6). Thus, even in these projects with high birth rates and probably only very limited family planning, the patterns for maternal age of deceased infants are different. The project in Bolivia" had one of the * Many famiiies could not be located in La Paz, and therefore the number of deceased infants for whom mother's age was unknown was large (855) and the distribution is based on those with ages known (1,935). The effect of this cannot be determined but is not believed to he sufficient to invalidate the findings. highest proportions of mothers aged 20-24 years-32.7 per cent. Higher percentages in this age group were noted only in tile three projects with the lowest birth rates (Sio Paulo, California, and Sherbrooke). Chaco Province was unique, having the highest percentage of mothers in the lowest age group under 20 years (26.7 per cent). Though there were similarities in the distribution by maternal age in the three projects with the lowest birth rates, there were marked differences too. The California project had a higher percentage of mothers under 20 years (23.7) than Sao Paulo (12.9), but only a very low percentage of mothers 35 years and over (6.1). In Sherbrooke, 37.7 per cent of mothers were in the age group 20-24 years but, only 7.7 per cent were under 20 years. Thus, the patterns of the age distributions of mothers of deceased infants differed markedly in thc 15 projects. NEONATAL AND INFANT MORTALITY BY AGE OF MOTHER To evaluate the implications of these wide differences among projects with respect to age of mother at birth of deceased child, the distributions of live births were obtained wherever possible so that death rates by maternal age could be calculated. Sufficient data on these (listributioins were available for only seven projects, five in Latin America and two in Northern America. Table 147 shows neonatal and infant mortality in these seven projects by age of mother in five age groups, while the rates in the five projects in Latin America are illustrated in Figure 119, in descending order of the infant death rates. In all five of the Latin American projects mortality was lowest for infants of mothers in the age group 25-29 years. It was excessive for infants of young mothers and for those of mothers 35 years and over. Death rates became very high for products of mothers 40 years and over but sufficient data for presentation were not available for all projects. From the data on the Chile project it is clear that when the infant death rates are lower, the curves for neonatal and infant mortality are closer t together than when the infant death rate is very high, as in the case of El Salvador. The neonatal rate for infants of mothers under 20 years in Chile--31.7 per 1,000 live births -was much lower than that in Sfio Paulo (52.3). Nevertheless, the patterns of neo
