To study the evolution of specific cases of fertility by age groups in the Autonomous Region of Valencia, between 1975 and 1990, and compare this development with the evolution on a national level.
The specific fertility rates were calculated for seven 5-year age groups within the female fertility period (15-49 years). The number of births per age of mother (Natural Movement of the Spanish Population) has been used and the denominator is the female population calculated be geometrical interpolation from the figures provided by different censuses and electoral roles for each one of the age groups. The study period is 1975 to 1990.
The evolution of the fertility rate in the Autonomous Region of Valencia is declining in all age groups except the 30-34 year age group, where fertility showed a slight increase at the end of the eighties, the same as in the rest of the country. Worthy of mentioned is the 15-19 year old group, with figures below the national level, and the 25-29 year old group, where the figures are greater than for the rest of the country as a whole. On a province (county) level, the development is similar to what has been described above. Alicante has the highest figure out of the three provinces (counties) for women in the 15-19 and 35-39 year age ranges.
The evolution of the fertility rate in the Autonomous Community of Valencia is similar to the development in the rest of the country, a slight increase being detected in women in the 30 to 40 year group, which is similar to what has happened in other European countries.
研究1975年至1990年间瓦伦西亚自治区按年龄组划分的特定生育情况演变，并将这一发展情况与全国层面的演变进行比较。
计算了女性生育期（15 - 49岁）内七个5岁年龄组的特定生育率。使用了每位母亲年龄的出生人数（西班牙人口自然变动情况），分母是通过对每个年龄组不同人口普查和选举登记数据进行几何插值计算得出的女性人口数。研究期为1975年至1990年。
瓦伦西亚自治区除30 - 34岁年龄组外，所有年龄组的生育率均呈下降趋势，该年龄组在80年代末生育率略有上升，与全国其他地区情况相同。值得一提的是，15 - 19岁年龄组的数据低于全国水平，而25 - 29岁年龄组的数据高于全国整体水平。在省（县）层面，发展情况与上述描述相似。在三个省（县）中，阿利坎特在15 - 19岁和35 - 39岁年龄范围的女性生育率方面数值最高。
瓦伦西亚自治区的生育率演变与全国其他地区相似，30至40岁年龄组女性生育率略有上升，这与其他欧洲国家的情况类似。
