Influences on Birth and Death Rates (Leaving Cert Geography): Revision Notes
Influences on Birth and Death Rates
Population growth patterns vary dramatically between countries due to several key factors that influence how many people are born and die each year. Understanding these influences helps explain why some nations experience rapid population growth whilst others face declining populations.
Four main factors affecting birth and death rates
There are four primary influences that determine birth and death rates in any country:
- Education and social status of women
- Standard of living
- Government policy
- Culture and religion
These factors often work together and can either reinforce or counteract each other's effects on population change.
Education and social status of women
The educational opportunities available to women and their role within society have profound impacts on both birth and death rates. This relationship demonstrates clear patterns between developed and developing nations.
Family planning refers to planning or controlling the number of children and the time period between having children, usually through means of contraception.
In developed countries
Women in developed nations typically receive comprehensive education and can pursue full-time careers. This educational access enables them to make informed decisions about family size through effective family planning. Educated women often choose to delay having children whilst establishing their careers, resulting in smaller family sizes and lower birth rates.
Additionally, educated women often possess better medical and healthcare knowledge. This knowledge significantly reduces infant death rates and increases overall life expectancy for families. The combination of career opportunities and healthcare awareness creates a demographic pattern of fewer births but higher survival rates.
In developing countries
The situation differs markedly in many developing countries where women may not receive formal education. These women frequently marry at younger ages and have more children. Without access to education, effective family planning sometimes does not occur, leading to continued high birth rates across generations.
Limited education also correlates with poor medical and healthcare knowledge, resulting in high death rates and low life expectancy. In some regions, cultural expectations further compound these issues. For example, in certain Islamic countries, women are expected to follow their husband's wishes regarding family size.
Case Study Examples: Education's Impact
Afghanistan demonstrates these patterns with a fertility rate of 5.6 children per woman. In sub-Saharan countries like Zambia, women often begin having children during their teenage years, contributing to high birth rates and significant natural increase. Zambia experiences a natural increase of 38 per thousand, with one-third of girls under 18 having given birth.
Standard of living
The economic conditions and quality of life available in a country create powerful influences on demographic patterns.
Standard of living refers to the quality of life and the opportunities available to a person in a country.
High standard of living (developed countries)
Countries with higher standards of living experience much lower birth and death rates compared to less developed nations. The economic reality of raising children creates significant financial pressure on families. In Ireland, for example, the estimated cost of raising a child to age 21 reaches £105,321, including expenses for clothing, healthcare, food, education, and other necessities.
This substantial financial commitment results in many couples choosing smaller families to manage economic pressures effectively. Additionally, developed countries provide better healthcare services, clean water supplies, and proper sanitation systems, which significantly reduce mortality rates.
Lower standard of living (developing countries)
In underdeveloped or developing countries, people lack access to quality healthcare services and financial support systems. Without adequate healthcare infrastructure, families often have as many children as possible to ensure enough survive into adulthood to care for elderly parents.
Child mortality rates remain high due to limited healthcare access. The absence of clean water, adequate food, and proper sanitation systems contributes to elevated death rates. In some cultures, having more male children is considered important for raising a family's social status, further encouraging larger families.
Government policy
Governments can actively intervene to control birth rates within their countries, either to reduce or increase population growth. These policies can have powerful influences on demographic trends through various incentives and restrictions.
Pro-natalist policies encourage population growth, whilst anti-natalist policies aim to reduce it.
Government interventions can include providing children's allowances, healthcare provisions (such as medical cards), and access to education. These factors can make countries more attractive for raising families. However, other considerations like high living costs and extended education periods can counteract pro-family policies.
Case Study: China's One-Child Policy (Anti-natalist)
China introduced its famous one-child policy in 1979 to reduce the country's rapid population growth. The government strictly enforced this policy, particularly in urban areas of eastern China like Shanghai.
Implementation methods:
- Families following the policy received incentives including higher wages and better educational opportunities
- Additional financial assistance was provided by the government
- Families violating the policy faced sanctions such as fines, employment termination, and withdrawal of government assistance including children's healthcare
Policy exceptions:
- Urban dwellers in the east faced stricter enforcement than rural western populations
- Couples where both parents came from one-child families could have a second child
- Couples could apply for a second child, more likely to be approved after waiting four years
Effects and consequences: The policy led to unintended consequences due to cultural preferences for male children. Couples began using scans to determine gender, often choosing abortion if the child was female. This created a significant gender imbalance with 117 boys born for every 100 girls.
The policy successfully moved China from stage 2 to stage 4 of the Demographic Transition Model very rapidly, dramatically slowing population growth. Birth rates fell below replacement level at 1.55 children per fertile woman.
By 2016, China removed the one-child policy to prevent rapid population ageing and further decline. However, the policy had created a cultural expectation of small families that persists despite policy changes.
Case Study: Romania's Pro-natalist Policies
Romania, with a current population of 19.8 million (declining by 0.29% annually), faced slow population growth during the 1960s. The government relied on a large workforce for industrial economic development and introduced policies in 1965 to increase birth rates.
Policy measures included:
- Making abortion illegal
- Making divorce difficult to obtain
- Introducing tax penalties for childless citizens over age 25
- Providing tax incentives and rewards for larger families
- Banning importation of contraceptives
Initial effects: The combination of financial rewards and restricted birth control led to a 93% increase in births between 1965 and 1967. However, this initial success was followed by significant increases in infant and maternal fatalities.
Long-term consequences: Despite early success, the total fertility rate had fallen to just 3.7 per 1,000 by 1975. The government failed to consider the relationship between socio-economic development and population growth. Money invested in agriculture and heavy industry rather than living standards meant the standard of living declined.
High poverty levels led many couples to place children in poorly-run state orphanages. By the mid-1990s, birth rates declined to more natural figures, currently averaging 9.27 per 1,000 whilst death rates average 11.9 per 1,000.
Culture and religion
Religious beliefs and cultural traditions can significantly influence population growth patterns, though their impact varies depending on a country's development level.
Religious influences on birth rates
Catholicism traditionally promotes high birth rates as the Catholic Church opposes artificial contraception and abortion. Countries with strong Catholic traditions historically experienced higher birth rates. In Ireland, family planning was heavily influenced by Catholic Church views promoting large families. However, as church influence declined and cultural attitudes changed, contraceptive use increased and family sizes decreased.
Hinduism, practised by the majority of India's population, does not oppose birth control methods. However, it does promote large families. Combined with India's cultural belief that having more sons brings economic advantages (through dowries from future wives), this has contributed to sustained high birth rates. Families view additional sons as economic assets, encouraging larger family sizes.
Development level and cultural influence
The impact of cultural and religious factors on birth rates correlates strongly with a country's development level. In highly developed countries, economic considerations typically outweigh cultural or religious influences on family size decisions. Conversely, in lesser developed countries, cultural and religious traditions often play larger roles in determining birth rates.
Key Points to Remember:
-
Education empowers choice: Higher education levels for women correlate directly with lower birth rates and better health outcomes for families.
-
Economics drive decisions: Countries with higher living standards see smaller families due to substantial costs of raising children, whilst poorer countries often have larger families for economic security.
-
Government policies work: Both China's one-child policy and Romania's pro-natalist policies demonstrate that government intervention can dramatically alter demographic trends, though often with unintended consequences.
-
Culture adapts to development: Religious and cultural influences on family size tend to diminish as countries develop economically, with practical considerations becoming more important.
-
Multiple factors interact: These four influences rarely work in isolation - they combine and sometimes conflict with each other to create complex demographic patterns unique to each country.
