1
What is an alternative term for the nuclear family structure?
Answer:
conjugal
The nuclear family, consisting of parents and their dependent children, is frequently referred to as a 'conjugal' family. This term emphasizes the marital bond between the husband and wife as the central organizing unit of the household, distinguishing it from extended family structures that are based on broader blood ties or consanguinity.
2
What is a common negative consequence associated with overpopulation?
Answer:
environmental damage
Overpopulation places immense pressure on natural resources, leading to deforestation, habitat loss, pollution, and increased carbon emissions. This strain on the ecosystem often results in significant environmental degradation as the demand for food, water, and energy exceeds the planet's sustainable capacity.
3
How is a blended family defined in sociological terms?
Answer:
is made up of natural parents’ stepparents natural children and stepchildren
A blended family, also known as a stepfamily, is formed when two individuals marry or cohabit and at least one of them brings children from a previous relationship into the new household. This structure integrates biological children and stepchildren into a single family unit, creating complex dynamics that differ from traditional nuclear families.
4
What is the approximate current total human population of the Earth?
Answer:
6 billion
While the global population has surpassed 8 billion in recent years, historical datasets often used in academic contexts have frequently cited the 6 billion figure as a benchmark for late 20th-century demographic studies. This question likely relies on older demographic data, making 6 billion the most appropriate choice among the provided options despite current population growth trends.
5
What demographic phenomenon occurs when a nation experiences a significant decline in birth rates while death rates remain constant?
Answer:
an ageing population
When birth rates fall significantly while death rates remain stable, the proportion of younger individuals in the population decreases relative to the older cohorts. Over time, this leads to an increase in the median age of the population, resulting in an ageing population structure, which has significant implications for labor supply and social welfare systems.
6
What are the defining characteristics of the urban process known as gentrification?
Answer:
middle class professionals renovating old city housing and using them as
Gentrification involves the influx of wealthier individuals into historically lower-income urban neighborhoods. This process typically leads to the renovation of housing stock, rising property values, and the displacement of original residents, fundamentally altering the socioeconomic character of the area.
7
Which urban ecology model posits that residential location relative to the central business district is determined by social class?
Answer:
concentric zone model
The Concentric Zone Model, developed by Ernest Burgess, suggests that cities grow outward from a central business district in a series of rings. It argues that social class and land use are organized based on distance from the center, with higher-income groups typically residing further from the industrial core.
8
What measure is theoretically proposed to prevent global overpopulation?
Answer:
zero population growth worldwide
Zero population growth (ZPG) occurs when the number of births plus immigration equals the number of deaths plus emigration. Achieving this globally would stabilize the total human population, theoretically preventing the negative externalities associated with unchecked population expansion, such as resource depletion and environmental degradation.
9
Which predominantly Catholic nation is characterized by a relatively high fertility rate?
Answer:
Mexico
Mexico has historically maintained higher birth rates compared to many European Catholic nations. This is often attributed to a combination of cultural norms, socioeconomic factors, and religious influences that prioritize larger family structures, although these rates have been gradually declining due to modernization and increased access to reproductive health services.
10
How is the crude death rate formally defined in demographic statistics?
Answer:
defined as the number of deaths per 1000 people per country per year
The crude death rate is a standard demographic metric calculated as the total number of deaths occurring in a population during a specific period, typically one year, divided by the total mid-year population, then multiplied by 1,000. This normalization allows for meaningful comparisons of mortality across countries with varying population sizes.
