Human Population - Coggle Diagram
Human Population
Birth & Death Rates
-
Infant Mortality Rate
the number of deaths in the first year of life divided by the number of live births, multiplied by 1000
-
-
Factors
Decrease in global death rates, while birth rates remained very high
-
Human Population Growth
Causes and Efffects
Technological Advancement : Better healthcare, sanitation, and agriculture increases birth rate and life expectancy.
Economic Development : Improved living standards and job opportunities contributed to life stability.
Urbanization : Migration to cities for better opportunity resuled in concentrated population and an increa se in population growth.
-
History
-
Agricultural Revolution (10,000 BCE) : Increass in food production through the agriculture reveolution led to gradual population rise.
Industrial Revolution (18th-19th century) : Significant population growth fueled by technological advancements and improbed living conditions during the industrial revolution.
Future Projections
Human Population Growth
Many countries are going through a demographic transition, characterized by a shift from high birth and death rates to lower birth and death rates. This transition is often associated with social and economic development, improved healthcare, and access to education.
Different Views
human ingenuity and technological innovation can overcome the challenges associated with population growth.
a rapidly growing population puts immense pressure on ecosystems, leading to deforestation, loss of biodiversity, and increased carbon emissions.
Proposed Solutions
Education empowers individuals to make informed choices about family planning and contributes to economic opportunities, which can influence decisions about family size.
Implementing community-based programs that raise awareness about family planning, reproductive health, and the benefits of smaller family sizes can contribute to voluntary reductions in fertility rates.
Policies that promote job creation, poverty reduction, and overall economic stability
Exponential, Logistic Growth, and Carrying Capacity
Explanation: Exponential growth occurs when a population multiplies at a constant rate over a fixed period, leading to a rapid increase.
Logistic Growth : Logistic growth considers limitations, such as resource availability, that eventually slow down population growth, leading to stabilization.
Carrying Capacity : Carrying capacity is the maximum population size an environment can sustain indefinitely, considering available resources and ecological factors.
Human Demography
Human demography is the study of human populations, including their size, distribution, density, growth rate, age structure, and migration patterns.
Key Components
-
-
Density : The number of individuals per unit of area, such as people per square kilometer.
Growth Rate : The rate at which a population's size changes over time, considering births, deaths, and migration.
-
Migration Patterns : How humans move around the world affecting the population. Example is the movement to urban ares.
Population Pyramid
Slow Growth
-
-
-
Slow population growth can reduce the strain on natural resources, as there are fewer people consuming goods and services.
-
Slow population growth may result in slower urbanization rates and less pressure on infrastructure development.
