ABSTRACT
PIP: In 1964 a 10 percent sample (5279) of all births registered in Rangoon was analyzed to determine fertility indices. The age specific fertility rate was found to be highest among ages 25 to 29; mean age for mothers was 27.5 years. The sex ratio of male to female births tended to increase with the advancing age of the mother with the exception of ages 40 to 44. Gross and net reproduction rates were 2.1295 and 2.0440 respectively, well within the theoretical range of value (0 to about 5). The margin between the gross and net reproduction rates indicates the extent to which mortality offsets fertility in population replacement; the net to gross ratio was found to be .96. Approximate length of generation was found to be 28.47 years. 46.2 percent of total births at first parity were attended by doctors; 75.2 percent of births for all parity were attended by qualified personnel, doctors and midwives while 1 in every 4 deliveries was attended by a "Lethe". As the number of births to a mother increased, the survival percentage declined sharply.^ieng
