Population Growth

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...

Longitudinal Research

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Infertility in Females

Infertility in Females

Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of endometrial...

Longitudinal Studies

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Emerging Adulthood

Emerging Adulthood

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during this...

Area of Science:

Demography
Reproductive Health

Background:

High-income nations face declining fertility rates.
Japan's population has been decreasing since 2015, following two baby booms.
Understanding fertility trends is crucial for demographic projections.

Purpose of the Study:

To investigate potential upward demographic trends in Japan after 1974.
To identify patterns that might indicate a future baby boom.

Main Methods:

Analysis of Japanese government data on live births, stillbirths, and induced abortions (1975-2014).
Comparison of two birth cohorts (1950 and 1975 baby boomers) across five-year age groups.
Examination of live birth rates, stillbirth rates, and abortion rates.

Main Results:

No overall increase in live births, stillbirths, or induced abortions was observed.
The abortion rate showed an increase between 1996 and 2002.
The second baby boomer cohort exhibited half the peak live birth rate and half the peak abortion rate compared to the first cohort, with abortions occurring at younger ages.

Conclusions:

Fertility trends in Japan, considering all pregnancy outcomes, have not shown an upward movement since 1974.
The study did not identify indicators of a future baby boom in Japan based on post-1974 data.
