Study Notes
Human Population
- Human population refers to the total number of humans living in the entire world, which is dynamic and continually modified by increases (births and immigrations) and losses (deaths and emigrations).
Importance of Studying Human Population
- The study of human population is important because it demonstrates significant quantitative and qualitative changes over time and space, impacting socio-economic development.
- Understanding population characteristics is crucial for adjusting to existing realities and for policy implications.
Characteristics of Human Population
- Population characteristics include population age distribution, race, gender, education, household income, poverty, life expectancy, and other aspects associated with community health.
Trends of Population Growth in Ethiopia
- Ethiopia is the second most populous country in Africa, with an estimated population of 114.9 million in 2020, ranking 12th in the world.
- The current population growth rate is about 2.6 percent.
- The population has been growing rapidly, with a doubling time that has decreased over the decades.
Historical Profile of Ethiopian Population Growth
- In 1900, Ethiopia's population was approximately 11.8 million, which increased to about 13 million in 1920 and 23.5 million in 1960.
- The population doubled in size between 1960 and 1990, indicating a doubling time of 30 years.
- The growth rate increased slightly after 1920, reaching 2.0 percent by 1950, and then rose to 2.8 percent in 1980 and 3.0 percent between 1980 and 1990.
Causes of Rapid Population Growth in Ethiopia
- High birth rates and declining mortality levels due to efforts to control diseases such as malaria.
Population Composition
- Population composition refers to the distribution of a population according to age, sex, occupation, language, religion, and other attributes.
Age Structure
- Age structure is the classification of a population into different age groups, revealing the pattern of distribution of members into different age categories.
- Age is a fundamental demographic characteristic of human population and demographic statistics.
Population Pyramid
- A population pyramid is a graphic representation of the distribution of a population by age and sex, providing a useful aid in examining the age and sex structure of a population.
