Abstract

The objective of this study is to determine the effect of cause specific death rates on age specific death rates for Tamil Nadu rural females during the period 1970-75 in various age groups. 2 regression lines have been fitted. The age specific death rates were taken as dependent variables and time as an independent variable; the age-cause specific death rates were dependent variables and time was an independent variable. In the analysis, the ratio of regression coefficients of 2 regression lines gives the effect of age specific death rates due to the j-th cause in the i-th group. The trend of mortality in the age groups (0-4) and (5-14) declines over the period 1970-75 and increases in the age groups (15-34), (34-54) and 55 and older. The causes of declining mortality in the 0-4 age group are cough, fever, other clear symptoms and other causes. The %s of contribution for this decline are respectively 14%, 41%, 21% and 72% to the overall decline in that age group. The cause group violence and injury, digestive disorders and causes peculiar to infancy have contributed to increase in the 0-4 age group death rates. Digestive disorders, coughs and other causes have contributed to declining mortality in the 5-14 age group. The cause group accidents and injury, digestive disorders, other clear symptoms, child births and pregnancy and other causes are promoted to increase the mortality of the 15-34 age group. The causes contributing to the increasing trend of mortality in the 35-54 age group are violence and injury, digestive disorders, coughs, other clear symptoms, child births and pregnancy. Digestive disorders and other causes contributed to the mortality increase in the over 55 age group.
