Populations increase and decrease because people leave one country (emigration) and enter another (immigration). A rise or fall in either the birth rate or death rate in a country can also cause populations to increase or decrease.
From 1950 to 1990 the population of Country W increased by 40 percent. From 1990 to 2012 the population of Country W increased by 10 percent. What is the percent increase in the population of Country?
To calculate the total percent increase in the population of Country W from 1950 to 2012, we first consider the original population in 1950 as 100. By 1990, after a 40% increase, the population would be 140. From 1990 to 2012, a 10% increase brings the population to 154. Therefore, the total percent increase from 1950 to 2012 is 54%.
What could cause a decrease in insect population?
an increase in the spider population
What are immigration and emigration and how do they affect population size?
Migration can increase population size by speading the animals (or people) over a wider area where there may be more resources. Migration (compression) into a single habitable area will increase the population density, but could cause either a numerical increase (more breeding) or a decrease (from limited resources).
