[[A dynamic model for populations reproduced by first marriage]]
Jinko Mondai Kenkyu. [Journal of Population Problems]
|January 1, 1992
Summary
Population models reveal that while delayed marriage can decrease fertility, it does not fully explain Japan's recent rapid fertility decline. Nuptiality and marital fertility are key factors in population trends.
Area of Science:
- Demography
- Population Studies
- Sociology
Context:
- Analyzes Japanese population data to understand fertility trends.
- Focuses on the impact of marriage patterns and marital fertility on population dynamics.
- Examines the relationship between nuptiality and population models.
Purpose:
- To construct a stable population theory based on nuptiality and marital fertility.
- To investigate the effect of the age shift in first marriage patterns on total fertility rates.
- To assess the contribution of delayed marriage to Japan's long-term fertility decline.
Summary:
- Develops a population model where childbearing occurs exclusively within first marriages.
- Demonstrates that stable population theory can be built upon nuptiality and marital fertility.
- Concludes that the age shift in first marriage patterns alone is insufficient to account for Japan's recent rapid fertility decline.
Impact:
- Provides insights into the complex factors driving fertility trends in developed nations.
- Highlights the limitations of focusing solely on marriage age in explaining demographic shifts.
- Offers a foundation for more nuanced population modeling and policy considerations.

Population Growth
28.7K
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.

Conservation of Small Populations
17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Population Genetics?
64.9K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Mechanistic Models: Compartment Models in Individual and Population Analysis
270
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Dynamic Equilibrium
63.1K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...
