Substantial Decline

SummaryAn analysis of Maori fertility shows that a transition from a high to a low level has begun. The crude birth rate has declined by nearly 28% during the period 1961–72; only a small part of this decline can be attributed to changes in the age–sex and marital status composition.A substantial decline in the fertility of older women has been observed and there are indications of the beginning of a major decline in the fertility of younger women. Since women aged 30–49 still account for 30% of total fertility there is enough potential for a further fertility decline in the later child-bearing years.Age patterns of fertility decline suggest that inter-marriage between Pakehas and Maoris is not a prime cause of the recent fertility decline. The factors which are thought to be responsible for this change in Maori fertility are rapid urbanization, a low level of infant mortality and an increase in the overall level of education.A further decline in Maori fertility will depend on the continuation of the tendency in fertility among the younger women.

Cash Benefits

In a period of very low fertility, effective family and childcare support policy measures are needed. From a wide range of instruments available to government intervention, we focus on public expenditures effects on short-term fertility. Using a sample of 28 European countries in a panel framework, we found that there is a small positive elasticity of crude birth rate to cash benefits related to childbirth and childrearing provided through social security system. Different public services provided to ease the burden of parents and all other benefits in kind, means or non-means tested, are found to be insignificant. These results are robust to alternative methods of estimation. Controlling for country heterogeneity by religion and by culture, some particularly interesting differences in birth rate determinants were highlighted as well.

Calving Intervals

Humpback whale mother–calf pairs from a currently unexploited population were observed in Massachusetts Bay between 1979 and 1985. During this period, 44 individually identified mature females were observed, with a total of 72 calves. Of the 20 mothers observed with more than one calf during the study period, 12 had two calves and 8 had three calves. The observed calving intervals were 1 year (n = 1), 2 years (n = 16), 3 years (n = 10), and 4 years (n = 1). The crude birth rate varied from a low of 0.045 in 1981 to a high of 0.103 in 1983 (mean = 0.075). An alternative calculation of reproductive rate yielded a range of 0.30–0.43 calves per mature female per year. Mature females were observed significantly more frequently in years when they had a calf than in years when they did not. Females with calves associate with other whales less frequently than females without calves. Observations of calves feeding suggest that weaning may begin when calves are 5–6 months of age. Forty-five of the 49 calves born before 1985 separated from their mothers during the calf's second winter, while 37 of the 49 were observed to return to the study area in 1 or more years after separation from their mothers. One calf is known to have died. Two females born during the study period returned with calves of their own in later years. The high return rate of calves in years after separation strongly suggests that the composition of a humpback whale feeding stock is determined matrilineally.

Indikator fertilitas, seperti Crude Birth Rate (CBR), Total Fertility Rate (TFR), General Fertility Rate (GFR), dan Gross Reproductive Rate (GRR), untuk mengukur kinerja pengendalian penduduk setiap tahun di level kabupaten/kota sejak otonomi daerah sering tidak tersedia. Aplikasi sistem informasi fertilitas Smart Fert sebagai alat untuk mengukur indikator fertilitas yang praktis, valid, dan mudah diaplikasikan sangat layak untuk dikembangkan. Tujuan penelitian ini adalah mengembangkan aplikasi Smart Fert serta menguji hasil perhitungan indikator fertilitas dari aplikasi Smart Fert dibandingkan dengan perhitungan dari hasil Sensus Penduduk 2010. Penelitian ini merancang aplikasi Smart Fert berbasis bahasa visual basic. Untuk mengukur ketepatan dan kevalidan hasil perhitungan fertilitas dari aplikasi Smart Fert, maka hasilnya dibandingkan dengan standar yang baik, yaitu hasil Sensus Penduduk 2010. Hasil penelitian menunjukkan bahwa hasil perhitungan fertilitas dengan aplikasi Smart Fert tidak menunjukkan perbedaan signifikan dengan hasil metode langsung Sensus Penduduk 2010. Dengan demikian, aplikasi Smart Fert dapat dipakai sebagai alat penghitung indikator fertilitas yang praktis, valid, dan mudah diimplementasikan untuk mengukur kinerja pengendalian penduduk di tingkat kabupaten/kota.

الملخص: تهدف الدراسة المعنونة بـ ((الزيادة الطبيعية لسكان محافظة دهوك للفترة (2007 – 2017) وتباينه مكانياً)) إلى بيان معدلات الزيادة الطبيعية أي الفرق بين الولادات والوفيات في محافظة دهوك حسب الأقضية بعد أن شهدت المحافظة زيادة ملحوظة خلال السنوات الأخيرة مما استدعت إلى الوقوف عليها، وقد تكوّنَ البحث من ثلاث مباحث: المبحث الأول تطرق إلى استخراج معدل الولادات الخام، والمبحث الثاني درس معدل الوفيات الخام، والمبحث الثالث درس معدل الزيادة الطبيعية (الحيوية) خلال الفترة حسب الوحدات الإدراية، وقد توصلت الدراسة إلى أنَّ معدل الزيادة الطبيعية في محافظة دهوك انخفضت من نسبة (3.3%) في عام 2007 إلى(2.1%) في عام 2017. Abstract:The objective of the study is to increase the natural increase in the population of Duhok governorate in the period (2007 - 2017) to indicate the rates of natural increase, i.e. the difference between births and deaths in Duhok governorate by district after the governorate witnessed a noticeable increase in recent years. The research may consist of three subjects: first, crude birth rate, second crude mortality rate, and third natural increase rate during the period according to administrative units.The study found that the rate of natural increase in Duhok Governorate decreased from 3.3% in 2007 to 2.1% in 2017.

A CONTINUED downward trend for births, slightly upward for marriages, and about the same rate as last year for deaths characterize the provisional vital statistics of the United States for 1965 (Table 1). Despite the falling birth rate almost 2,000,000 persons were added to the United States population through the excess of births over deaths. Births in 1965 were down about 7% from 1964, bringing the total number, estimated at 3,767,000, below 4,000,000 for the first time in 12 years. The number of births was the lowest since 1951, giving a crude birth rate of 19.4 births per 1,000 population and a fertility rate of 96.7.
