Decrease In Total Fertility Rate Research Articles

Unmet need for family planning and related difficulties among married women of childbearing age in Bandung Slum, Indonesia.

This study was conducted to assess what factors cause women of childbearing age (15-49 years) who live in slums in Bandung City, Indonesia to experience unmet need for family planning. Unmet need for family planning is a phenomenon in the population sector that requires serious and immediate treatment because it can inhibit the increase in Contraceptive Prevalence Rate (CPR) and decrease in Total Fertility Rate (TFR). A cross-sectional survey was conducted from February to July 2021. 304 women were selected as respondents using a purposive sampling technique. Univariate and multivariate regression analysis was performed using STATA 16. The result is 29.3% of women have unmet need for family planning, while the factors that influence the occurrence of unmet need for family planning include marital age, family income, experienced a child's death, number of children living, women's decision-making power, and media exposure. Increasing access to information and free family planning services for married couples is important, especially for low-income families with many children.

PEMAHAMAN DAN DUKUNGAN SUAMI TERHADAP KEIKUTSERTAAN IBU MENJADI AKSEPTOR KB IUD DI KECAMATAN SECANGGANG LANGKAT

The decrease in TFR (Total Fertility Rate) will be closer to the condition of the population growing in balance, a strategy is needed in the implementation of the family planning program. Activities that can be carried out are promoting long-term effective contraceptive methods. This study aims to determine the understanding and support of husbands for the participation of mothers in becoming IUD KB acceptors in Secanggang District, Langkat Regency. The research design used in this study was an analytical survey with cross sectional approach. The sample in this study was 30 respondents who came and wanted to do family planning. The data analysis used was univariate and bivariate analysis. The results of this study indicate that there is a significant relationship between Husband's understanding of the participation of mothers in becoming IUD family planning acceptors in Secanggang District, Langkat Regency, with a pvalue of 0.000. And there is a significant relationship between the husband's support for the participation of mothers in becoming IUD family planning acceptors in Secanggang District, Langkat Regency with a p value of 0,000. It is hoped that it can increase respondents' knowledge about contraceptives so that they can support and understand their wives in choosing contraceptives.

Genetic load and biological changes to extant humans.

Extant humans are currently increasing their genetic load, which is informing present and future human microevolution. This has been a gradual process that has been rising over the last centuries as a consequence of improved sanitation, nutritional improvements, advancements in microbiology and medical interventions, which have relaxed natural selection. Moreover, a reduction in infant and child mortality and changing societal attitudes towards fertility have led to a decrease in total fertility rates (TFRs) since the 19th century. Generally speaking, decreases in differential fertility and mortality have meant that there is less opportunity for natural selection to eliminate deleterious mutations from the human gene pool. It has been argued that the average human may carry ~250-300 mutations that are mostly deleterious, as well as several hundred less-deleterious variants. These deleterious alleles in extant humans mean that our fitness is being constrained. While such alleles are viewed as reducing human fitness, they may also have had an adaptive function in the past, such as assisting in genetic complexity, sexual recombination and diploidy. Saying this, our current knowledge on these fitness compromising alleles is still lacking.

Adolescent motherhood in Bangladesh: Trends and determinants.

BackgroundWhile studies on fertility and contraceptives issues are available, until recently adolescent motherhood has not received enough attention among policy makers in understanding adolescent motherhood in Bangladesh. We aimed to examine the trends and determinants of adolescent motherhood among women aged 15–49 years.MethodsFor trend analysis we used all the 7 waves of Bangladesh Demographic and Health Survey (BDHS, 1993–2014) data but for multivariate analysis 4 waves of BDHS (2004–2014). Two separate analyses were carried out on ever married women aged 15–49: (1) teenage girls aged 15–19 and (2) adult women aged 20 and above.ResultsThe prevalence of adolescent motherhood had declined to a slower pace from 1993 to2014 (from 33.0% to 30.8%). Lower spousal age gap and higher education were found to be associated with lower likelihood of adolescent motherhood both among teenage girls [OR 0.447 (0.374–0.533)] and adult women [OR 0.451 (0.420–0.484)]. Teenage girls in the poorest wealth quintile [OR 1.712 [1.350–2.173] were more likely to experience adolescent motherhood than the richest wealth quintile. Teenage girls who had no education were found to have 2.76 times higher odds of adolescent motherhood than their counterparts who had higher than secondary education. Concerning the time effect, the odds of adolescent motherhood among adult women was found to decline overtime.ConclusionsDespite substantial decrease in total fertility rate in Bangladesh adolescent motherhood is still highly prevalent though declining from 1993 to 2014. Social policies including those addressing poverty, ensuring greater emphasis on education for women; and adolescent mothers in rural areas are needed.

Fertility change in the American Indian and Alaska Native population, 1980–2010

Background: Since 1990, Vital Statistics reports show a dramatic decline in the total fertility rates (TFRs) of American Indian and Alaska Native (AI/AN) women in the United States. Objective: We study whether the decrease in TFRs is due to a real change in fertility for a stable population; a compositional change in who identifies as AI/AN; or a methodological issue stemming from differences in identifying race across the data systems used to calculate fertility rates. Methods: We use data from the decennial US Census to study change in AI/AN fertility from 1980–2010. Results: We find declining TFRs when fertility is calculated within a single data system. Additionally, although TFRs are relatively stable within the subgroups of married and unmarried AI/AN women, the proportion of AI/AN women who are married has declined across birth cohorts. Conclusions: The decrease in TFRs for AI/AN women is a real change in fertility patterns and is not due to differences in racial identification across data systems. Contribution: We update knowledge of AI/AN fertility to include the decline in TFRs between 1980 and 2010.

Reckoning females’ education as a determinant of fertility control in Pakistan

PurposeThe purpose of this paper is to obtain empirical evidence on the impacts of socio-economic and demographic factors on the fertility decisions taken by a common family in developing countries like Pakistan. Also, this study contravenes the conventional orthodoxy of childbirth decisions of a family by enlarging the canvas and conjectures the fundamental nexus amongst female’s education, fertility and contraceptive use.Design/methodology/approachThe study is based on micro-level data, obtained from the Pakistan Demographic and Health Survey (2012-2013) which is the third survey carried out in Pakistan. Demographic and socio-economic profiles of 13,558 ever-married women, aged 15-49 years, were randomly selected from Gilgit Baltistan and the four provinces of Pakistan. Three dependent variables are used in empirical analysis i.e. current use of contraceptives, total fertility and cumulative fertility. In order to estimate the probability of contraceptive use maximum likelihood, Probit technique is employed with ordinary least squares on reduced form specifications of total fertility and cumulative fertility models.FindingsThe empirical results proved the hypotheses that educated females practice more family planning through modern contraceptives which leads to a decrease in total fertility rates. Some significant links among females’ education, contraceptive use and fertility define the quantity – quality trade-off and opportunity cost of time. Evidently, female education provides maturity and awareness of family size which is necessary to take crucial economic decisions.Research limitations/implicationsThe empirical evidence suggests that maximum efforts should be made toward women’s education. The current standard of education in Pakistan is not enough to overcome the long-standing problem of excessive child birth. This could be done with the help of public – private partnership as the measures taken by the government alone are insufficient. The government should initiate some adequate measures such as education and awareness about contraceptive usage at the secondary school level that could be a vivacious step to support fertility reduction.Practical implicationsThe framework used in this study provides a broader intra-household income–expenditure approach. With a smaller family size, the household’s income would be shared among fewer individuals. It is highly probable that parents would be more attentive if they need to look after a few children. That is the best way to progress their children with limited resources.Social implicationsFrom the socioeconomic perspectives, educated parents plan the ideal family size which allows them to spend more on their children’s upbringing.Originality/valueThis study captures the magnitude of fertility decisions with the relevance of the wife’s education because the present practice in Pakistan does not allow higher education for married women. This is why this study could be used as a benchmark for further study in the same area.

Fair Plan 9: Engineering Human Population to Help Safeguard Earth’s Climate

Our Fair Plan to Safeguard Earth’s Climate reduces the emission of greenhouse gases to zero over the 80-year time period 2020 to 2100. To accomplish this, humanity must reduce its carbon intensity—the amount of CO2 emitted per unit of energy—and its energy intensity—the amount of energy needed to generate a unit of Gross World Product. As shown in our Fair Plan 8 paper, reducing the future growth of the human population can also contribute to the reduction in greenhouse-gas emissions. Here, we explore this further. We project the historical decrease in Total Fertility Rate (TFR) across the 21st century toward its logistical asymptotic Reference value of 2.04 Births Per Woman (BPW). We then engineer the asymptotic TFR beginning in 2020 to 1.95, 1.85, 1.75, 1.65 & 1.55 BPW. We project the population across the 21st century for the Reference and engineered TFRs. We do so using the results of Basten, Lutz and Scherbov (2013) for the population evolution across the 21st century for 8 constant TFR values (=2.50, 2.25, 2.00, 1.75, 1.50, 1.25, 1.00 & 0.75 BPW). We find that purposefully engineering the asymptotic TFR can significantly contribute to achieving the reduction in greenhouse-gas emissions needed to transition to our Fair Plan to Safeguard Earth’s Climate.

The Effect of Urbanization on China’s Fertility

The relationship between urbanization and fertility decline is known to be inverse in developed countries. However, the nature of this relationship in developing countries that already have relatively low fertilities is not well-understood. This study aims to illustrate how much urbanization contributed to China’s fertility decline between 1982 and 2008 and forecasts how much it can contribute to future reductions in fertility. The study examines changes in the total fertility rate (TFR) at both the national and provincial levels, given regional differences in the urbanization rate. The results show that changes in rural fertility behavior accounted for most of the decline in the national TFR between 1982 and 2008. This finding suggests that official birth control policies were instrumental in curbing China’s population growth. However, urbanization was responsible for about 22% of the decrease in TFR during this period, and its effect was especially important during the latter years (2001–2008). In most provinces, urbanization associated with a decline in provincial-level fertility. The forecasts indicate that urbanization will become the primary factor behind future declines in national fertility. Given the negative effect of urbanization on the TFR, it is possible to relax the one-child policy without having adverse implications for population growth.

THE EFFECT OF HOUSE PRICE ON FERTILITY: EVIDENCE FROM HONG KONG

This article extends a standard Beckerian model of fertility behavior to formulate the effect of house price (HP) on fertility. The simple model predicts a negative effect of HP on the number of children for a representative household not only through the income effect but also through the compensated substitution effect. The prediction is confirmed by a cointegration analysis applied to the annual data at the aggregate level covering the period from 1971 to 2005 in Hong Kong. It is found that a 1% increase in HP is significantly related to a 0.45% decrease in total fertility rates (TFRs), which is robust in sensitivity tests with an alternative model specification and alternative measures of TFRs. This implies that high HP inflation can account for about 65% of the fertility decrease in Hong Kong in the past four decades. (JEL J13, J11, C32)

Effects of Chemical Sympathectomy on Contralateral Testicular Histology and Fertility in Unilateral Vasectomy

Unilateral obstruction or injury to the vas deferens can result in significant injury to the contralateral testicle. Although various pathways have been proposed, the mechanism of contralateral testicular deterioration remains controversial. The present animal study was performed to evaluate the effects of unilateral vasectomy on ipsilateral and contralateral testicular histology and fertility in rats that were chemically sympathectomized neonatally. The study comprised 40 male albino rats: 20 received a placebo and the other 20 underwent chemical sympathectomy neonatally. When 60 days old, each group of 20 rats was divided into two groups that underwent either a sham operation or an operation to create unilateral left vasectomy. Eight weeks after surgery, each male rat was housed with two known fertile female rats for 25 days, and then their testes were harvested. Mean seminiferous tubular diameters (MSTD) and mean testicular biopsy scores (MTBS) were determined for each testis. Although MSTD and MTBS were not significantly different between groups, chemical sympathectomy prevented the decrease in total fertility rates of the rats with unilateral left vasectomy in our study. Prevention of this decrease by chemical sympathectomy suggests that the sympathetic nervous system may play a role in the testicular degeneration associated with vasectomy.

Extremely high fertility of a sedentarized Bedouin clan in south Jordan: a genealogical-demographic approach to long-term change

A Bedouin-origin clan with extremely high fertility in south Jordan sedentarized in a village in 1948. In this paper, based on our genealogical-demographic data collected from this clan, we elucidate the long-term demographic change that this clan has undergone. Our results highlight differences in fertility indicators among the early (1950–1969), middle (1970–1989), and late (1990–2004) periods. In particular, the total marital fertility rate (TMFR) was 4.756, 9.852, and 9.146, respectively, and the total fertility rate (TFR) was 3.589, 7.214, and 5.189, respectively. Taking age-specific indicators into account, the increase in TFR or TMFR from the early to the middle periods was attributable to increased rates of childbirth among middle-aged and older women, presumably associated with improvements in maternal nutrition and increased demand for children as agriculture labor, while the decrease in TFR from the middle to the late periods was caused by a delay in females’ age at marriage and an increase in the number of unmarried females. The fertility of this clan has been high, especially in the late period, and it is estimated that its population will double by 2030, implying the urgent necessity to reduce fertility to prevent overpopulation that threatens the people’s subsistence adaptation.
