[Live-birth rates by age of mother and total fertility rates by urban and rural areas].

Live birth rates by age of mother and total fertility rates by urban and rural areas in Japan are generally decreasing. Japanese women ages 15-49 were studied. Graphs presenting fertility rates according to age in 1975 and 1980 in urban and rural areas show that fertility rates are considerably higher in rural areas than in urban centers (by as much as 20% for the 25-29 age group). In a table showing urban/rural total fertility rates and distributions among prefectures in 1975 and 1980, the prefecture with the highest total fertility rate (2.88495 in 1975 and 2.37804 in 1980) is Okinawa and the lowest total fertility rate is found in Tokyo (1.62287 in 1975 and 1.43693 in 1980). The average total fertility rate in 1980 was 1.82849; in urban centers it was 1.78919 and rural areas, 1.92105. Finally, a comparison of total fertility rates by urban and rural areas and by age shows that in 1975 the rural fertility rate was .16 higher than that of urban areas, and that in 1980 all fertility rates (total, urban, and rural) were lower, with the rural fertility rate decreasing at the same rate as did the urban fertility rate in 1975. It is interesting to note that between 1975-1980 birth rates have been decreasing in both urban and rural areas in all age groups except for the 30-34 year old group which in urban centers was higher in 1980 than in rural areas. This can be attributed to the recent trend among Japanese women of delaying childbirth.
