Many factors can affect population: people are born or die and people move around to find work or escape natural disasters and wars.

The fertility rate is the average number of children per family. The fertility rate in Europe is about 1.6. This number is calculated by dividing the total number of children by the total number of families.

Natural changes in population can happen when there are more births in a country than deaths.
This results in an increase in population. If there are more deaths than births, population decreases.

Migration is the movement of people from one area to another. People that live and work in one country, but are from another country, are called inmigrants. People that leave their country to live in a different one are called emigrants.
When there are more inmigrants than emigrants, population grows. If the number of emigrants is higher than the number of inmigrants population decreases.
