The effects of minimum wages on teenage birth rates

Planet Earth, now home to about 6.5 billion human beings, has thus far disproved the doomsayers. In 1798, Rev. Thomas Robert Malthus predicted that population would outrun food supply on the assumption that human numbers would increase at a geometric rate while food would be limited to arithmetic increases. Then, in 1968, Stanford University professor Paul R. Ehrlich issued a similar warning in his book The Population Bomb, in which he predicted that hundreds of millions of people would die of starvation in the 1970s and 1980s. Both men underestimated humanity’s resourcefulness—as well as its scientific and technological acumen—in figuring out how to provide for its growing numbers. Still, there’s little doubt that the Earth’s human carrying capacity has a limit. And growth can’t continue indefinitely without more of the significant environmental health impacts we are already seeing. In addition to documenting exactly how much growth is occurring, scientists are now interested in trends reflecting where such growth is occurring and the effect of factors such as consumption rates and migration on sustainability of the Earth’s resources.

The goal of this research is to examine family structure due to the decline in birth rate in Tuva Republic and Republic of Khakassia in the early Xxi century. The authors attempt to reveal the factors affecting the decline in birth rate, and determine other components of the dynamics of family structure (number of families, family size, parenthood status). The object of this research is the transformation of the structure of family institution, while the subject is the dynamics of current family structure in the two republics. The article reviews the leading factor of the dynamics of birth rate. The authors’ special contribution consists in covering the problem of decline in birth rate as a result of transformation of family structure in the regions of Southern Siberia. The scientific novelty lies in studying the regional component of decline in birth rate under the influence of a set of factors, including the transformation of family structure. The area of application of the research results is the activity of ministries and departments, as well as special courses in the university on the discipline Familistic. The following conclusions were made: 1) birth rate is affected by various factors, such as education of women, urbanization level, financial situation in family, household structure; 2) state of the key components in the dynamics of family is characterized by the increase in a number of households, reduction in their size, complication or simplification of family structure, prevalence of one-child and growth of the portion of two-children families.

Decline in Birth Rate: A Growing Iran Concern In 2010-2015, the 83 countries with below-replacement fertility accounted for 46 per cent of the world’s population. The most populous countries with below replacement fertility are China, the United States of America, Brazil, the Russian Federation, Japan, Vietnam, Germany, the Islamic Republic of Iran, and Thailand, in order of population size

Dynamic adjustments could be a useful strategy for mitigating the costs of acute environmental shocks when timing is not a strictly binding constraint. To investigate whether such adjustments could apply to fertility, we estimate the effects of temperature shocks on birth rates in the United States between 1931 and 2010. Our innovative approach allows for presumably random variation in the distribution of daily temperatures to affect birth rates up to 24 months into the future. We find that additional days above 80 °F cause a large decline in birth rates approximately 8 to 10 months later. The initial decline is followed by a partial rebound in births over the next few months implying that populations can mitigate the fertility cost of temperature shocks by shifting conception month. This dynamic adjustment helps explain the observed decline in birth rates during the spring and subsequent increase during the summer. The lack of a full rebound suggests that increased temperatures due to climate change may reduce population growth rates in the coming century. As an added cost, climate change will shift even more births to the summer months when third trimester exposure to dangerously high temperatures increases. Based on our analysis of historical changes in the temperature-fertility relationship, we conclude air conditioning could be used to substantially offset the fertility costs of climate change.

The article examines key indicators of the demographic crisis in Ukraine, highlighting manifestations of the nation’s aging and natural population decline.It’s determined that understanding and analyzing the demographic situation allows for predicting changes in the size and structure of the student population, which is crucial for the effective development of higher education in Ukraine. Considering the trends of declining birth rates and an aging population, it is important to adapt admission strategies for students and educational programs accordingly. The examination of the demographic crisis helps identify key challenges, such as a decrease in the number of high school graduates, which can impact competition within the higher education environment.The trends examined in the article, including the decline in the birth rate of the Ukrainian population, the aging of the nation, the level of migration, and the loss of the civilian population due to the war, enable us to characterize the situation in Ukraine as depopulation. Notable changes in the demographic landscape and shifts in the population structure occurred after February 24, 2022, including irreversible human losses, population emigration (over 10 million people), and a decline in the average birth rate. A correlation was identified between the number of births each year and the dynamics of educational services’ capacity. It was observed that higher education in Ukraine will confront significant demographic challenges in the next 17 years. In the context of the strategic goal to restore Ukraine’s human capital, the article suggests viewing higher education as an effective instrument of state policy in a cyclical process: attaining higher education, integrating graduates into the national economy, ensuring financial stability, fostering active citizenship, and promoting loyalty to the state—all contributing to an improvement in the demographic situation.

In most industrial nations the long decline in birth rates has led to overcapacity of primary education; secondary schools are now cushioned against the same declines only by extending their services to a larger part of the population (King, Moor, & Mundy, I975). The consequences for higher education as a whole can be predicted on the same basis, but colleges and faculties of education are likely to confront an unusual and relatively prolonged decline in their enrolments. Those colleges which are most narrowly vocational will be more vulnerable than faculties of education which have significant liberal education, research, or graduate teaching programs. Of all Canadian provinces perhaps Ontario faces the greatest problem because of its concentration of research in the Ontario Institute for Studies in Education with the operation of many facilities essentially as post-degree certifying programs. Similar jeopardy may face particular institutions in several other provinces. An earlier paper (Ray, 1978) discussed reasons for the decline of teacher preparation in England and Wales, the United States, and Ontario. In that analysis the decline was termed a collapse because of the coincident effects of declines in birth rate, popular demand for more schooling, and short-term professional careers. Although there remain

Birth rates in Canada and the United States declined sharply in March 2020 and deviated from historical trends. This decline was absent in similarly developed European countries. We argue that the selective decline was driven by incoming individuals, who would have traveled from abroad and given birth in Canada and the United States had there been no travel restrictions during the COVID-19 pandemic. Furthermore, by leveraging data from periods before and during the COVID-19 travel restrictions, we quantified the extent of births by incoming individuals. In an interrupted time series analysis, the expected number of such births in Canada was 970 per month (95% CI, 710-1200), which is 3.2% of all births in the country. The corresponding estimate for the United States was 6700 per month (95% CI, 3400-10 000), which is 2.2% of all births. A secondary difference-in-differences analysis gave similar estimates, at 2.8% and 3.4% for Canada and the United States, respectively. Our study reveals the extent of births by recent international arrivals, which hitherto has been unknown and infeasible to study.

Incidence of teen births in the United States taking into account racial disparities

This paper documents a set of facts about the dramatic decline in birth rates in the United States between 2007 and 2020 and explores possible explanations. The overall reduction in the birth rate reflects declines across many groups of women, including teens, Hispanic women, and college-educated white women. The Great Recession contributed to the decline in the early part of this period, but we are unable to identify any other economic, policy, or social factor that has changed since 2007 that is responsible for much of the decline beyond that. Mechanically, the falling birth rate can be attributed to changes in birth patterns across recent cohorts of women moving through childbearing age. We conjecture that the “shifting priorities” of more recent cohorts, reflecting changes in preferences for having children, aspirations for life, and parenting norms, may be responsible. We conclude with a brief discussion about the societal consequences for a declining birth rate and what the United States might do about it.

We estimate the effects of temperature shocks on birth rates in the United States between 1931 and 2010. We find that days with a mean temperature above 80°F cause a large decline in birth rates 8 to 10 months later. Unlike prior studies, we demonstrate that the initial decline is followed by a partial rebound in births over the next few months, implying that populations mitigate some of the fertility cost by shifting conception month. This shift helps explain the observed peak in late-summer births in the United States. We also present new evidence that hot weather most likely harms fertility via reproductive health as opposed to sexual activity. Historical evidence suggests that air conditioning could be used to substantially offset the fertility costs of high temperatures.

The Indonesian Fertility Survey (IFS) was conducted in the 5 provinces of Java and the province of Bali in 1976 as a part of the World Fertility Survey. The IFS results compared with results from the 1971 population census and the 1973 Fertility-Mortality Survey provide the means for assessing changes in fertility and contraceptive use as well as program impact from the late 1960s to 1976. The decline in the crude birthrate using the IFS results is about 11% between the late 1960s and 1976 (from 38 to 34) again with the largest drop in Bali and no decline in Yogyakarta. More than 1/2 of the decline in the birthrate (and more than 3/4 of the decline in Bali and Jakarta) occurred after 1972-1973. Marital fertility over the 1960-1976 period declined for women in each age-group over 25 while increasing among younger women. The decline among older women is consistent with patterns of fertility decline found in other developing countries. For the sample as a whole the family size at which a majority want to stop childbearing is 3.4 children. There was a substantial increase in knowledge of contraception over the 1973-1976 period. In 1976 75% of of ever-married women knew of a method dispensed by the national family planning program (oral contraceptive IUD condom). 54% of currently married respondents to the 1976 IFS indicated that they knew of at least one place or person they could visit to obtain contraceptives. Among currently married women aged 15-44 there was a tripling or near tripling between 1973 and 1976 in ever-use of contraception (from 12% to 39%) in current use (from 11% to 28%) and in use of modern methods (from 9% to 23%). The use of OCs IUDs and condoms offered by the program more than doubled (from 9% to 21%).
