Question

what are the determines of an increase in population size

Answer 1

Take a minute and think about all of the different people you interact with in a given day. For most people, this would include family, friends, co-workers, and strangers. A population is often described as a group of individuals of the same species that inhabit the same area. Therefore, all of the people you encounter each day are part of your population. Other examples of populations include the dandelion plants growing in a field or the cockroaches that inhabit a single house.

On a larger scale, you can think of all humans on Earth as the human population. As of 2011, the human population exceeded seven billion people! Although the human population has been around this size for most of us for our entire lives, the population has not always been so large.

Around 10,000 years ago, before the invention of agriculture, it is estimated that the human population was only a few million people worldwide. After the invention of agriculture,
the human population began to grow slowly until the 1900s, when a rapid increase in the human population began. With increases in technology and medical advances, the human population was able to reach three billion in the 1960s. Since that time, the population has more than doubled and continues to increase.

Answer 2

The major determinants of population growth are

1) Birth rate - Birth rate refers to the number of live births per thousand people in a year.

2) Death rate - It refers to number of live deaths per thousand people.

3) Migration - It is the movement of people across regions and territories.
