When the pyramid is triangular then the population is?
There are three main trends in populations that affect the shape of a population pyramid. The first is when there are both high fertility and high mortality rates among younger members. This type of population, known as “expansive,” creates a sharp triangle shape in the graph.
What does the shape of population pyramid indicate?
The shape of the population pyramid efficiently communicates considerable information about the age-sex structure of a specific population. A broad base and sharply tapering sides (a true pyramid shape) reflects high fertility rates and high mortality rates in younger age groups.
What are the 5 stages of population pyramid?
There are five stages of population pyramids: high fluctuating, early expanding, late expanding, low fluctuating, and natural decrease.
What are the 4 types of population pyramids?
And while every population pyramid is unique, most can be categorized into three prototypical shapes: expansive (young and growing), constrictive (elderly and shrinking), and stationary (little or no population growth). Let’s take a deeper dive into the trends these three shapes reveal about a population and its needs.
What are the three main factors that cause population change?
The three main causes of population change
- Births – usually measured using the birth rate (number of live births per 1,000 of the population per year).
- Deaths – usually measured using the death rate (number of deaths per 1,000 of the population per year).
- Migration – the movement of people in and out of an area.
How do the 4 major factors influence population change?
What we might talk about as population size is actually population density, the number of individuals per unit area (or unit volume). Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
What is population change class 8?
Population change refers to the change in the number of people due to birth, death and migration during a specific time. If the birth rate is more than the death rate, then there is an increase in population. If the death rate is more than the birth rate, then there is a decrease in the population.
What are the factors affecting the growth of population?

- Promote family planning.
- Make education entertaining.
- Government incentives.
- 5) One-child legislation.
What is carrying capacity and how does it affect the size of a population?
Carrying capacity can be defined as a species’ average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
Are humans at their carrying capacity?
Understanding Carrying Capacity Human population, now nearing 8 billion, cannot continue to grow indefinitely. There are limits to the life-sustaining resources earth can provide us. In other words, there is a carrying capacity for human life on our planet.
What happens when carrying capacity is exceeded?
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
